BERKELEY DeHAVILAND BEAVER

This is a laser cut reproduction of King size line kit 3-2 by Berkeley Models the U.S.A.F. liaison aircraft. This original kit used a high lift, under camber airfoil on the 48 inch wing span and was designed for radio, free flight or controlline. The repo is designed for .049, or R/C .099, in radio control configuration, but the new plans are for the Norvel .074 R/C. This reproduction was one of a group made up a few years back. You get sheets of more than 280 high quality laser cut balsa and plywood parts, plus ones not originally in the kit. This has every die cut part in the original kit, plus numerous other parts that were only pictured, like all the numerous gussets which the builder was to cut from scrap wood. (Lets face it, is simplier to cut the scallops in the wing faster using the laser than by hand. See pictures linked below) The parts came off a quarter million dollar machine, not a cheapo engraving machine as a few famous, but small outfits are today advertising with much ballyhoo. Much of the cut-to-fit shown on the original plans is eliminated, and replaced with notched trailing edges, complete laser cut horizontal stabilizer sized to the optional "radio control" as per plan, all formers for the fuselage, fuselage sides, doublers, tips, gussets, and a beautifully shaped rudder which fits the model, not the plan. Assemblies have mortised ends so that even a poor builder will end up with a straight product. This reproduction contains the modifications which were shown on the original plan that were to suit radio control, such as notched floor for servos, elevators, a quick fit on/off wing mounting, the floor & firewall are cut for hardwood engine bearers (instead of a hard to locate aluminum mount per original), Nyrod mounts, rudder spars are slotted and centered for DuBro hinges and many other little ease to building design changes and extras. If you intend to power by electric, say so, and will substitute in a blank firewall instead of one meant for glow. Pretty easy using Autocad now, but time was spent to ensure that the parts to this model FIT better than the original die cut ones did. Plywood and balsa parts have been toleranced and shaped to fit the model within 0.010" of the final shape. This is a Semi-kit, not a complete kit. For completion, you will need to obtain items not in this kit like stripwood, a sheet of 1/16" balsa, a couple of 1/2" slab blocks, dowel, celluloid, metal landing gear and wheels, engine cowl, covering, bolts and several other small items. A big plan resembling the original is included, drawn to same outlines, but hass been redrawn to strainght lines, and radio configurations. This is a model for a BUILDER/FLYER, not a collector.

The Semi-kit with plan costs $55 each and will be sent via U.S.P.S. in a triangular shipping box, to ensure the model is built and not stored. This model has a large amount of room for electric propulsion, but builder will need to move floor further down so as not to ruin the C.G.

Berkeley Cessna 170

This is a reproduction of the once popular glow powered kit number 2-3 in the Berkeley lineup from the 1950's. Again, all laser cut wood which has been slightly altered to fit properly and eliminate much of the sand papering of the original kits. This is at about 1/6 scale and has a 72 inch span kit with copious room inside the fuselage for radio control gear. The original kits were designed for single channel and a .35 glow engine which it is doubted that anyone will consider. There is room for most any obsolete radio you may have. Not only will all the original die-cut parts be included in this semi-kit, but extra parts for control surfaces are now included. At this time, the original five piece wood block cowl is not included, which enables the aircraft to compete in the SCALE catagory at V.R.C.S. events. You will need to craft one, or substitute a fiberglass one like from Stan's FiberTech of Oregon. The original model wing was made up from custom milled leading and trailing edges, which are not availabe at commercial outlets, and thus ribs have been altered to accomodate more easily obtained shaped wood. Copies of original plans are available here also, however the set of redrawn plans are more popular and contained with each order. About 300 laser cut balsa and plywood parts on 14 slabs of wood, plus the two big sheets of plans, and shipping will be $88 and available with some 3-5 week delay occasionally as obtianing plywood seems to be a problem often.

The Berkeley Helioplane type YL-24

Not too popular any more, but back when helicopters were short legged, slow and fragile there were several variants made of S.T.O.L. aircraft. The most famous of the S.T.O.L. aircraft were made by Helio, and this particular version was of the earlier four seat version. The model, like the original, is built for going out taking off and landing in a short confined space like the end 15 feet of your home concrete driveway. No need to travel a distance to a suitable flying site. This 1 inch scale model A/C is complicated and equally rugged representation of the original kit, except that it includes all those parts which were only drawn onto the plans. Many prototypes were made before the new reproduction kit and CAD plans were completed. The builder was then expected to fabricate those parts, but now they are actually included in this new kit. Those parts which the builder was expected to originally fabricate or hog out of blocks of balsa wood are now efficiently cut to shape, eliminating much weight and time. When you receive the semi-kit, it may look like fewer parts, but there are SUBSTANTIALLY more now, and easier to install.

It will be available as a semi-kit, electric drive version. A glow version is designed around the Norvel 061 is no longer available after Sept. 2007. Each semi-kit will come with operating rudder, elevator, aileron and large flaps for those short take offs and landing. It will require at minimum a five channel receiver of light weight construction, 2 or 3 miniature servos and two more standard sized servos. The new Helioplane is designed around the 1 3/32" diameter by one inch long popular "Outrunner" brushless electric motor of the 100-200 Watt range, and requires a suitable electronic speed control of 20 ampere or so. The plans now explain how to construct alterations noted on the original design, and features like a new one piece wing, simplified motor mounting, and drop out floor for access to the interior radio gear. This modern electric engine version containing laser cut parts and plan sheet is $51 (less shipping) for a limited time only.

Jetco Mooney Mite

This was one of the earliest kits in the C.A. Zaic Jetco Model Company line up. It is a near scale kit of the little 65 H.P. single seat performer. The Mooney company got off the ground with this very small and light aircraft produced from 1947 through 1954 as the model M-18 and a singular model M-19 built for the military.

This model aircraft is HUGE for a light weight 1/2A powered model, and the plans are very detailed. The wingspan is about 45 inches, and the plan has been revised in respects to parts which are now available and those not during the era of the original. It has non-retractable landing gear as in the original kit. The semi-kit features more than 230 laser cut parts, built in mounts for a Norvel .074 engine, removable wing and many of the parts needed to build the dummy engine. This non-retractable gear version is still set up like the original kit for rudder, elevator, plus throttle and steerable nose wheel. A later retracting gear version will feature everything working and a different wing. Due to the narrowness of the fuselage, this is NOT a good choice for those thinking of converting to electric.

This version semi-kit is $51 which includes new CAD drawn plan, parts and comes your choice of shipping via U.P.S or U.S.P.S. based upon a 1 3/4 pound package.

Berkeley Cessna Bird Dog

A very popular model of the Cessna Army Liason and Artillery Spotting aircraft of the Korean War era. The original plan also indicates it to be used by the New York Air National Guard. The Berkeley kit 4-1 was later picked up by Fox models in 1960 and kept in production for yet a few more years. The original 1 inch scale kit was for a free flight or controlline with 36 inch span model using .049 glow power. The semi-kit was developed for Scale Squadron of Southern California and has a few laser cut parts revised especially for three channel radio control purposes. The delicate fuselage is not as large as many models of the era, however it is more than adequate for late model radio gear with small sized servos. The current version is modified to fit the popular Norvel .061 glow power, and will be only available until late spring of 2007. Thereafter the Berkeley Bird Dog reproduction is to have firewall parts modified for installation of new brushless electric power. The original rubber and OK Cub powered Bird Dog reproduction of 2002 is still available at BH Plans. Due to the laser cutting process, this later version has some weight reduction to benefit those using rubber power, electric or glow. A one piece window frame is included now as an extra, which speeds things up for the builder, and eliminates the lumpy-bumpy, made up from parts type.

The new electric version will not cost any more than previous versions but will be in and out of stock about every three months. The wood for the semi-kit, a new plan, and shipping via U.S.P.S. will be $44. If ordered in combination with a Butterfly noted below, the box weighs the most, and you then only need to add in one dollar for shipping when in combination with it. Thissaves you a few dollars in shipping then.


The Prettner Curare'

This is a reproduction of the once popular International glow powered, F3A style aerobatic model airplane. The new CAD plan and parts developed here are compiled off of four sources of original plans. These plans vary in age, one set is an early style obtained from German source, another from Sweden, one from the orient and the basic design from Model Airplane News. The model evolved over the years, and none of these agree with any version of currently available plans nor one another.

The winning version is to be initially offered, which is based mainly upon the plan shown in the Model Airplane News article of 1976. This version had a 64 1/2 inch wingspan, and used a Webra Speed 10ccm glow engine. The PassTime design is different in that it is revised for an all wood wing (like as used on the earlier version) making it lighter than the foam wing version, it uses the now more easily obtainable Hobbico retracting landing gear units (at about 1/5th the cost of original units), modern radio gear, a not-so expensive (Asian or domestic) 10ccm glow motor, and popular hardware like from DuBro, C-G and others which are shown on the plan for the wing and other locations. All of which is aimed to allow the builder to fly a famous and winning design, but not show in the wallet. Now please note here too, that this aircraft was intended for power by a very hot 10ccm (or .61 Cu.In.) glow motor. Anything else will be mediocre performance.

At present time, kits from the Orient, like from M Kato of Singapore, are currently going for more than $200, but with some judicious planning here, plus lower cost (and currently available) hardware, your model will will be in the air for even less. If you have ever tried to build this well known model from the original plan, well rest assured, for errors in original plans have been discovered, adjusted and even corrected. This also means the PassTime parts will not fit any model made off the prior plans, no matter what version you may have. It will however be to the same outlines, but the insides are different and it will be a bit lighter than the kit version. The builder may need to add in some ballast if using modern radio equipment.

Two prototype models were constructed in summer of 2006. One for fit and the other for flying. On a follow-up weekend, the flying version when flown by two neophytes had whacked the ground so hard it bent the crankshaft. I do not have an extra Webra 10ccm to experiment with, so a lesser expensive glow engine is being designed in to the model. The new Curare' will be not be a complete kit, but released as a semi-kit, being the customer will obtain only the laser cut parts and the mentioned CAD drawn plan. At this time there looks to be more than 165 laser cut parts on sixteen sheets of wood that vary of 1/16", 3/32", 1/8", 3/16", 1/4" balsa, with aircraft grade plywoods of 1/32", 1/16", 3/32", 1/8" and 1/4" used in construction. No shortcuts here, for all parts will be full length and to proper size. You will notice from enclosed picture that the original wing required 1/16" shear webs which are also now being laser cut in order to save some building time. To cut each of these by yourself, will take more than one hour, but allow about twenty minutes to pop out and glue into place the pre-cut ones. For that thin beam of light is so much faster than the razor blade. The builder will also need to obtain some standard flat balsa sheets and some triangular strip stock to finish off building. In looking over the quantity, it best to consider your skills before sending off remittal for it takes a lot of sandpapering here too.

A preliminary picture of the plan and when about 60% of the parts involved were done as of third week of May 2007. Price at present time is $79 per semi-kit and for a copy of the CAD plan. Due to oversize, shipping is to be via United Parcel Service from zip code of 92410 on a parcel of 4 3/4 pounds, size of 50 by 7 by 7 inches.


ATLAS

by Wolfgang Matt

This is a reproduction of parts for the once popular International glow powered, F3A style aerobatic model airplane. Plans for this model aircraft vary in age and are still available via Model Airplane News, and none of these agree with any version of currently available plans nor one another.

The winning version is to be initially offered, which is based mainly upon the plan shown in the Model Airplane News article of March 1976. This version had a 65 inch wingspan, and used a Webra Speed 10ccm glow engine. The PassTime design is not like the modified version once available as foam wing and fiberglass fuselage from Southern R.C. but is like the original all wood wing making it lighter than the reproductions. In addition, this varies in design from the kit once available via Kato of Japan, especially in the nose area. These parts are aimed to allow the builder to fly a famous and winning design at present time, with some lower cost. Your model will will be in the air at an even less cost.

A prototype model was constructed and plan sheet has been mailed out for inspection as you read this. The new Atlas will be not be a complete kit, but released as laser cut parts only from PassTime. At this time there is not as many laser cut parts as on the previous Curare' but they will be of 3/32", 1/8", 3/16", 1/4" balsa, with aircraft grade plywoods of 1/16", 3/32", and 1/8" used in construction. No short cuts here either, for all parts will be full length and to proper size. The original wing required 3/32" shear webs which are also being laser cut in order to save some building time. If you were to cut each of these by yourself, it would normally take more than one hour, but instead the pre-cut ones allow just a couple minutes to pop out and be glued into place. As that thin beam of light is so much faster and accurate than the razor blade. To complete, the builder will also need to obtain some standard flat balsa sheets and some triangular strip stock in order to finish off building. In looking over the quantity, it best to consider your skills before sending off remittal for it takes a lot of sandpapering here too. This model was originally designed for a 10 ccm glow engine with a muffler, but was more often flown with a tuned pipe. No provision for pipe mounting or ducting has been done.

Price at present time is $63 per semi-kit, and is available on a monthly basis. A whole new plan has been prepared, and unlike the plan offered via M Kato of Japan, this one is full size and whole wingspan. The original article about the Atlas which mentions some tuning information is noted too. Shipping weight via United Parcel Service is expected to be about 4 2/3 pounds. The laser cut wood alone weighs in at about 3 lbs. 4 oz. and then add in your glow engine weight, the radio gear, retracts, fuel tank, covering and even using today's heavier wood, it still comes out lighter than an original. You can calculate the shipping cost via their on-line computing methods.



Ecktronics Butterfly

The Butterfly is a small 1/2A racer that was designed back in 1963, and even today is not for simple weekend flying. It has a one piece 36 inch wing and is built to light weight standards (like how the F3A pattern aircraft builders of the 1970's used to do). If unfamiliar with this style of construction, read up in some of the older R/C Model Builder magazines of the 1980's. The somewhat square fuselage has a lift off top to access everything inside. It was originally for one channel radio gear but three channel is more appropriate today. You will need to install a DuBro L215 Vee tail mixer. This does not mean heavier, but things have been redone inside the cockpit area. It was initially set up for a Norvel .061 Big Mig or AME glow engine using beam mounts, or per plan the K&B .049 Stallion, Fox .07 or Cox Baby Bee. However, the cockpit interior measures 2 1/2" by 2 1/2" by 2" as to benefit those thinking of electric conversion. An extra vented, firewall in now included for those wanting to go the electric conversion route (preferred). Annoying, is that the builder must supply some large sheets of acetate for the square and ugly looking canopy, and a flat dural aluminum 1/2A size landing (appropriate looking) gear. Either of these usually can be obtained for about $1 each at swap meets. Plus then a couple of nice light sheets of balsa wood for finishing off the flat areas. You will also need a pair of the light weight Robart foam tires which need to be trimmed and sanded to streamline. Original colors was of a golden-bronze with bright gold pin striping. These are not easy to find today, due to them not being popular colors, seems ever.

Cost will be $29 per semi-kit, which includes a copy of original plan. Shipping cost is generally $10.50 within the U.S.A. via Priority mail offered by the U.S.P.S.


Berkeley Piper Tri-Pacer

This is a whole new version of the Piper Tri-Pacer which was offered by Berkeley Models during the 1950's as their kit 3-1. The new model is of the familiar 44 inch span, but now a bit more sturdy than the original design. This does not mean heavier, but things have been redone inside the cockpit area and the wing is now one piece. It is currently been redesigned for modern radio control, and some weight savings. It was originally designed for .10 -.20 glow engines, but the plans have been revised for an electric brushless outrunner motor, of about 150 to 250 watts, making it a VERY GOOD choice for that power. There have not been any problems with progress, except that other projects have scooted in front of this one and a Beta kit is now offered as of August 2007. The Prototype model of 2007 revealed a tendency of the wing to "flap" and thus a major deviation from the original is that of a one piece wing about 44 inches long is to be built now.

This project contains about 110 parts overall. The parts for the model will be available in a version with ailerons (as per detail on original plan) or without, but the customer needs to specify which version before ordering. Same cost of $48 for either version. Be sure to visit shipping to determine a cost there.


Livewire Specials

For the parts/plans on the Livewire Kitten and The original Livewire Trainer you now need to go elsewhere. Full set of parts are currently available at BHPlans.com. Should you need plans, originals can be obtained via Fran Ptaszkiewicz of Tonawanda New York. Or vist the web-site at: http://www.deboltplans.com/

The Interceptor Mark Five, 68 inch wingspan, 50-60 power. New plans from the old plans as published in American Modeler 1966, but now with revisions for more modern radio gear. This was sort of an advanced aerobatic aircraft for the era and it was the first model aircraft to be within four points of a perfect score in 1965, only foiled by faulty soldering within the receiver. If you missed reading about the development of the 'Ceptor Five, then a reprint of the text from the original article is printed on the plan. A remarkable story in itself. A full set of more than 150 laser cut parts on fifteen big sheets of 1/16", 1/8", 3/32", 3/16", 1/4" balsa, 1/16" A/C plywood, 1/32" A/C plywood, 1/8" A/C plywood will make for interesting construction but at only $49 per set plus shipping. The new CAD drawn plan is available for $15 each which shows late model radio gear and glow engine, but still makes it still acceptable for PATTERN competition at vintage events. Note, that this is not an easy assembling model and will require the builder to have some skills, plus the fuselage requires a fiberglass nose piece not available through DMECo or Hartman any more.

The Stit's Playboy This is a model which had been planned to be included in to the DMECo series of boxed kits, but it just did not happen. In correspondance with Hal DeBolt before his death, there really wasn't a reason or good memory as to why it had been axed at the last moment. Low wing models were still a bit new to the international community in aerobatic events, but now within the U.S.A. there where many models resembling the Astro Hog and had been sucessfull for a couple of years. The prototype model was taken to Berne Switzerland, in 1960 and competed in the first ever World R.C. Championships on behalf of the U.S.A. team. Due to the high winds, Hal Debolt crashed it on the first day of the event. He had to finish up the second day of competition with a more familiar biplane. For a better read on this, refer to the November 1960 issue of Model Airplane News magazine.

However, the original plan has been located, plus a couple of blueprints showing variants. From those originals, another plan was drawn up in CAD using details off of each plan. Each of the variations and much of the original construction items are noted on the plan. The model features a wingspan of 66 inches and a broad chord of 13 inches. The model had originally been designed and equipped with one of the first K&B Green head .45 glow engines back in 1960. However, one of the more modern .40 sport glow engines would provide equavalent power today. This not an easy model to build for it is of light wing construction, along the lines of modern competition models. The fuselage is a rather straight forward box construction, and can be built without any unusual problems.

The Stit's is of standard radio control construction, except for the wing, and the builder will need to supply some vintage looking 3 1/2 inch diameter wheels, a broad and flat dural landing gear, a 1/6 scale Hellcat celluloid canopy, and some 48 inch long wood strips. The semi-kit will consist of twelve laser cut sheets of balsa and aircraft plywood, plus the noted CAD plan all for $66. This model additionally has laser cut plywood wing jigs in order to ensure straightness.

The Viscount, 59 inch wingspan, 29 to 45 power. The DMECO Viscount is significant in flying model history in that it was the first model airplane to be designed with retracting landing gear in mind, plus other subtle features. The original model had incorporated air brakes, large area ailerons, swept back fin, and other features before they became popular on purpose built competition models. The Viscount was active in International aerobatic competition from about 1961 through 1964.

As can be seen right here, the reproduction model is of standard radio control construction now. Of interest is that the builder will need to supply some vintage looking wheels, an over the counter canopy, and some 48 inch long wood strips. If also using a vintage glow engine, the builder will need to install brakes (similar to DuBro) on the wheels. The more than 80 piece semi-kit will consist of nine laser cut sheets of balsa and aircraft plywood, plus the noted CAD plan all for $62. These parts require a large shipping container for total weight of three pounds, and must be sent via United Parcel Service. The single engine plan will shown three variants, but parts will only be available for the most popular version, the type two. The new Viscount reproduction is a much easier to build than the Playboy, or the Interceptor.

The Tom Brett Perigee, a DMECO favorite as per below advertisement. New parts to fit old plans, but with revisions for more modern radio gear and ease of construction. These plans are from BOTH the article of American Modeler in January 1963 and directly off the mylar original which was actually drafted by Tom Brett as modern radio gear has upset the C.G. and it is being brought back into configuration again. The original ran in competition with a modified K&B .45 but the plans call out for a more popular K&B .35 series 62 in R/C version. The DMECO kit called for .19 to .40 engines, but the builder may not want to go that small. This is one of those advanced aerobatic aircraft which pre-dated the more popular Top Flite Taurus. It is very tricky to fly, and should only be attempted by those with experience in such A/C. Laser cut parts are available, but must be ordered in sets of three due to shipping size problems. This kit also incorporates ribs with "feet" in order to get correctly aligned wing surfaces, and plywood fuselage jigs to ensure that is also being built straight.

The Sorcerer. A 63 inch wingspan swept wing model of 1961 (see below, left). This was an advanced airplane during the time it was available. It was also one of the first model aircraft to use a plastic/mylar film for covering that predated the more common Monocoat. It is very fast, designed for aerobatic competition using 40-45 glow power. This model is a handfull to fly and if not familiar with flying a swept wing model aircraft of the early 1960's then pass this one up. Choose a more respectable aerobatic flying model like the Interceptor Five, for this aircraft had a tendency to snap roll without warning.

The Primer by Gerald Nelson (see above right). All new plans and laser cut parts for this sturdy .45 sized trainer have been generated from a 1965 edition of American Modeler. It was a favorite trainer using ailerons back then, and a good introduction into vintage aircraft today. Plan is completed and laser cut parts are available. A new CAD drawn plan is included with each semi-kit. The original fuselage siding was one piece nearly 48 inches long, (see remarks on shipping via the M.A.N. Curare' noted above) and this size is not always held in stock here. Visit shipping for final estimated shipping costs based upon a 3 pound parcel though.


Half-Way Done Projects

To which you can provide the finished touches and complete

The XD-7 Hustler-Delta

This was a design by Weldon Smith about in 1962 that became a legend. It is a total redraw of the original plan, plus parts, and I flat have not had enough time to really wring it out. It is designed (via wing area) around a .19 Cu. Inch glow engine. Not a hot .15 or a hot .21 or something else, but a .19 like a Veco. Long before the rules got revised, this was the model airplane to own if you wanted to go Pylon racing and it was later on kitted by Midwest Models also. It is 44 and 5/8 inches wide overall, and designed for three channel radio gear (which was quite expensive back when) and the whole development article is reproduced on the new plan, (but near useless to a builder). The article goes into ways as how to bend the cap strips such that no rib is required, however I have included a few four gram ribs of 1/16" in the parts pile to make this easier for me and you to bend to correct airfoil instead. Cost and availability for this one are estimated to be near $43 each semi-kit (less shipping).

The Aristo-Cat

This was a design by Bud Atkinson about in 1964 that became a legend. It is a class two aerobatic model airplane(, that as per rules of that era consists of working rudder and elevator and optional engine control). The original plans were done by good friend Ron West, but as he mentioned were rushed and then contained several errors or omissions. Everything was sort of rushed through to be printed up in a Model Airplane News magazine article. Those errors and omissions on that original plan have been found now and have for the better part corrected. The whole project is sort of half way done now, the prototype flown, and all of the parts shown on reproduction and original plan are completed and laser cut, but again I do not have the time to wring it out. It has a near to 790 square inches of wing area over a 63 inch wingspan, and is now designed for one of the modern .45 to .47 glow engines (with muffler), instead of the original Veco .45 glow engines.

The Propo-Cat

This was a design by Bud Atkinson about in 1966, sucessor to the Aristo-Cat. It is another class two aerobatic model airplane(, that as per rules of the era consists of working rudder and elevator and optional engine control). This aircraft was featured in American Modeler magazine during 1966, and the new plan has the text laid out also. The whole project is done, but half way done like the Aristocat noted here. All parts shown on original plan and the reproduction are completed and laser cut, but again I do not have the time to wring it out. It has a near to 61 inch wingspan, and works best with one of the obscure but modern .45 to .47 glow engines which has a muffler, instead of the original Veco .45 shown.

The 1/2 Wave

This was a 1954 design and is an antique, but very classic design of the era. I first flew mine back a couple years ago at the local dry lake. It only takes a Cox Baby for power, one channel of your radio gear for rudder only control too and optionally the other channel for the engine speed control, but it better be aimed the correct direction for the nose wheel is not steerable. And I did not like that. Maybe you will not either. It also takes some strange width wood for the fuselage sides that cannot be easily obtained anymore. But I recently came upon some here.

The Wave has a 38 inch wingspan, and is suitable to electric power for those thinking of such. For there must be near to one cubic foot of room in the cabin area. The covering has been pealed back some to reveal a system of construction on this very early PassTime Reproduction. New plan has been created in CAD to benefit the customer if no original can be located. It is done now, flown in original format and will be later on offered in combination with the Blippy by Aubrey Kochman circa 1957, for they resemble one another.

TheRadio Roger

I flew a reproduction to this very simple model of circa 1958 back many a few years ago, using a very tired Cox Baby Bee engine and a Cox two channel radio. Although a fresh and tight Cox glow motor would have performed better, this made my whole flight a bit harrowing, for it hugged the ground. But flew just the same. The original design was for an OK Cub .075 diesel. However there are plenty of glow motors that can be obtained across the counter today which can outperform the diesel. The original design was also flown with B batteries, and on single channel and escapement. Via the (illegal) Cox radio gear this gave reliable right and left control. Which is reccomended today, unless you desire to go the Original, and risky route involving an escapement. A whole new plan has been made up based upon the old one, plus there are reproductions of the balsa and plywood parts already laser cut out and available. Not, many of these for there is not a lot involved here either. The majority of the cost for a copy here involves the weight in shipping the box to you. It has a 50 inch wingspan, and is suited for (at minimum) a fresh Cox Baby Bee glow engine, and one or two good channels with servos on an obsolete and small radio. And fly in a BIG FLAT area like a dry lake as I did if you choose to under power it. Expected retail price for the semi-kit is to be less than $20, plus shipping costs on a near two pound package.

Berkeley Models power boats

Right now I got about four of the Berkeley Model Chris-craft power boats completed and tested. Aiming for eight soon too. Problem is that many of these had specified an electric outboard motor, and I only got one, and it is near fifty years old. I can't find a suitable replacement today, and thus do not list these as being available. A few of the original boats had inboard electric drives shown, and this has been tried also, but my motors are obsolete Mabuchi (of which I have a few extras here) and the place that sold them is no longer in business any more. So can you see my point here. I do not want to list these items as being available, unless the customer is able to supply the now obsolete powerplants and I hope you see the point here.

Right now have done and ready to ship without correct powerplants: The Chris-Craft Cruiser 22, The Chris-Craft 21 Cruiser (rescaled up a bit for inboard uses), The Chris-Craft 18' outboard cruiser (scaled up to 18 inch long), The Chris-Craft 16 foot long open 16" runabout.

The Berkeley Cessna 172

This was a modernized version of the original Cessna 172 by Berkeley (see notes on Piper Tri-pacer above). If you have never seen them before, just take a look at the rear section to a 1950's era American Modeler magazine. That classic Cessna near vertical fin is promenently shown in these old advertisements. When Berkeley Models was bought up by the three, it survived a few more years past 1960 under the SIG models of Iowa banner.

The problem was not in the original design, but in the available equipment of the era. For the radio gear shown was of early 1950's vintage single channel with a whole bunch of items the model builder was expected to fabricate. From elevators, to ailerons, motor controls, flaps etc. and all on single channel. Today we have "cheap" radio receivers that do all of that and one function at a time, too, and part of the original problem was in the three piece flapping wing. I think that I got this all got resolved now with a one piece 54 inch wing, new parts just for multi function operation, modern .15 glow or electric sized motors, cheap but powerful receivers and radio servos, and a smaller amount of "sanding to shape" as noted on the original plan. I built this from personally owned airplane kit and plan which have been owned since the early 1960's when things cost less. Only over the past few years has it been tested (and all original flaws discovered again) updated and a new plan made off the old one. Due to other pressig projects I just do not have the time to complete testing and evaluation of the semi-kit now. I warn you though, this one takes some 1/20th balsa to complete, and that is hard to find, plus the C.G. is located in a place that is tough to adjust to. It worked OK with heavy B batteries and a tube radio, but with today's light weight equipment, you are going to have trouble shoving all the weight up near to the plywood firewall.

The DeBoltSpecial

This was a 1967 design by Harold DeBolt who died in 2004 and was featured on the old ABC television Wide World of Sports circa 1965. It was a state of the art model airplane Pylon racer and WINNER. The original plans were sort of done in pencil on vellum, contain very few details and was sort of rushed through for the aircraft to be elegible with the A.M.A. and the network. The new plan contains the text from the article as printed in American Modeler in 1967 plus notes from Hal when he flew the creation. The original plan had notations as to airfoil, for Mr. DeBolt was an early advocate of airfoil testing and this is the version included on the plans and parts. Not the version as shown on the later "Hobby-Helpers" plan. There were no errors or omissions in the magazine plan as done by Hobby-Helpers but the original version was a bit different in that it showed details to a Midget Mustang model, which is hereby omitted and so is the secondary wing and airfoil. This new/old Pylon Racer plan contains a few modifications as on the original as already mentioned by Mr. DeBolt, plus all parts shown on original plan and most of the laser cut ones, but again I do not have the time to wring this model out. There was a kit version offered for a brief time and they pull premium prices today, but if all you want is a reproduction, and one in that the parts fit, this is the way to go then. It has a near to 50 inch wingspan and used one of the original K&B Torpedo .40 glow engines which are now hard to find today, the plan has been modified to show one of the more modern series 75 K&B front rotor glow engines (without muffler) like from the 8011 series by MECOA. If you are in to aerobatics, get the Interceptor noted above. If you are in to old time Pylon Racing, try the Special.

The Stark-Shark

This was a 1964 design by Dick Allen who currently lives in Florida and aided in the reproduction of plans and parts. It is a class two aerobatic model airplane WINNER. The original plans were sort half with and without ailerons, contain several errors and was sort of rushed through to be printed up in a American Modeler magazine. The new plan contains the text from the article plus that of Art Shroeder when he flew the recreation for the quarterly of the Vintage Radio Control Society. There were no errors or omissions in the original plan but the overlaying of the different building methods takes up a lot of space. The Class Two version of Elevators, Rudder and Motor control plan is now sort of half way done, it contains a few modifications like nose gear and firewall treatment as offered by Mr. Allen, plus all parts shown on original plan (for the Class Two version) are completed and laser cut, but again I do not have the time to wring it out. Mr. Allen made yet even more modifications to the original long after the original airplane became obsolete and these are to be shown on a Class Three version plan, not yet completed. It has a near to 60 inch wingspan and originally flew with a hot Veco .45 but now one of the modern .45 to .47 glow engines may be more suitable.

The Windmill

This was a 1966 design and is a class three aerobatic model airplane WINNER. It is a handfull to fly also, for it only has engine and rudder control. The original plans were sort of half given in an American Modeler magazine. The new plan contains the text from the article. This aircraft originally flew with a biggie K&B Green head .45 glow motor of which can easily be outdone by one of the cheapo O.S. Max .40 LA glow motors today.

This Class Three version has an unusual UP canted glow motor and only has controls for Rudder and Motor control which make it a handfull to fly today. It has about 49 inch wingspan with a broad chord and uses one of the modern .40 glow engines. If you have never flow such a rig, it is best to read up on how to handle one today.



I have a few more "Half-Done Projects" needing a bit of development time and will be listing them, or possibly taking certain ones out of that page and putting them into the actice catagory. Also take a look at the attached "Old or Former Projects" listing here. If anything shown gives an interest to you, contact me at the below note, and can then further inform you of the circumstances.
