will roll and loop very well, but I can't get it to snap! I have to move some equipment aft to move the CG aft, but I haven't yet figured out what! With a flat -bottom airfoil (stolen from Bob Kopski's Revolt), it will fly very, very slowly and is very maneuverable. I originally used an APC 10X6 prop on the Snapdragon, but found the 11X5 better matches the low top end speed of the model, plus it gives better acceleration in the low and slow aerobatics I prefer. I will be providing plans for the Hot Dawg to Elliott Boulois (Institute Of Silent Flight). Due to his medical problems, I don't know when Elliott will be able to make the plans available for sale, though. He has already started making Hot Dawg kits, but their availability also depends on his health. As I said above, DesignCAD ate the Snapdragon plans (actually, it only ate the fuselage plans. I was able to salvage the wings and horizontal stab). I still have most of the printouts I used to build the existing Snapdragon, but I'm keeping those in case I want to build another.

Hot Dawg & Snapdragon William J. Bowne email: beaglvr@erols.com
Both models are scratch built, all-wood, drawn via CAD, and both have the same wing area - 450 sq. inches. Unfortunately, I no longer have the complete plans file for the Snapdragon, due to a fault in DesignCAD 2D. The Hot Dawg started out as a low-winged Ol' Dawg, but I changed the airfoil from a Clark YH to flat-bottomed one to make the landings even more gentle. The aspect ratio, span, etc., are the same, although I made the tips a little more rugged as they are more vulnerable to hitting the ground than on the Ol' Dawg. The Hot Dawg has a geared Astro C05 (brushed) on 8 1400 SCRs, turning a Master Airscrew 11 X 6. It weighs 54 ounces RTF. The black area on the fuselage top is the battery-changing hatch. Covering and trim are Monokote. The graphic of a dog chasing its tail was done by printing a reversed clip art image on an overhead projector acetate. I cut out the image, sprayed the BACK with white paint (to match the Monokote), and then glued the image in place with 3M-77. The Snapdragon was inspired by my seeing several airplanes with laminated, curved surfaces. In almost 30 years or R/C flying, I'd never built any laminated surfaces, but I have now! I was very happy with how the laminated wingtips and horizontal stab came out. The Snapdragon is powered by an Astro 035, turning a Zinger 11 X 5 via a Master Airscrew 3:1 gearbox, and powered by 10 SCR 1000 cells (Thanks to Ken Myers for the idea!). It weighs 48 oz, RTF. All covering (including the numbers) is Micafilm. The only non-Micafilm covering is the red trim striping, found in a bargain bin at a closing discount department store (another benefit of oil-less electrics <G>). Where I screwed up was in making the nose too long and the elevators too small. Nose-heavy, Snapdragon

1/4 scale Scheibe Tandem-Falke Gudmund Thompson Email: Gudmund@aol.com Ottawa Remote Control Club
I thought that you may be able to use a short note and picture from me showing an electric project. Last fall I ordered, from Tom Hunt, a T-1000 motor/belt drive system, with the suggestion that I would mount it in a 1/4 scale Scheibe Tandem-Falke, to be built from Cliff Charlesworth's plans. Well, the project has been a success. The dewalt motor, on 24 cells, has sufficient power to effect the type of flights that I want. The model weighs under 17 pounds in the electric mode and just continue
