I generally followed your plans with the exception that the nose cone is one piece 1/32nd sheet molded over 9 stringers, and the wheels are open cell foam which I glued to a 1/16 plywood disk and sanded to size in a Dremel tool. The floating axle bungee works great! The airframe, wheels, prop and two servos as shown in the photos weighs 102 grams. I'm estimating a 203 gram total flying weight. That's about 5 grams over your high-end weight. Maybe I can try a lithium battery to get some weight reduction. I'm planning on coverlite and glue stick, and haven't allowed for the weight of pilots or motor details.
I had five good flights of 3 minutes or so without a recharge, and there was still 10 minutes at full power after I got home before the Pixie 7 BEC cutoff motor power at 6.05 volts. It flew well. Not as much lateral stability as my GWS Tiger Moth but observably slower. I'm looking forward to a windless dry day to try it outdoors. Thanks for a good design. Thanks again for your help. PS - That's me and my wife in the cockpits. |
