RE: engine for my new 60-91 ugly stick
I just repowered mine with the DLE 20cc gas. It has ENDLESSPOWER and thats just in the first few flites. I had to move the rudder and elev servos to the tail. I took the gas tank out of the front and moved it back under the wing just over the landing gear. I also moved the batteries (2 4.8v 2000mah nimh) to the back of the under the wing compartment.I built a nice rack to hold the batteries in and installed thepush pull switches for the engine and radio powerin that location also. The front compartment where the gas tank was is where the engine electronics, 42% kill switch, plug in type fuel filler and throttle servo are all mounted. this setup allows you to balance the weight without adding any. Because of the larger prop and ground clearance,I extendedthe landing gear and used4inch wheels. They look like they came off a bush plane. When I get achance I'lltryto post pictures.
