any idea on prop for the us 25cc? Would 16x8 be ok
Got mine mounted in a Great Planes Super Stearman. Initially ran an APC 17 x 8 which is fine but going to try a 16 x 10 as it gets more run in. Very scale like performance, ie fairly lazy and gutless, but great for stooging around. Spring starter is a nice idea and works well but no choke is a pain on an enclosed engine. Even going full throttle with ign off for a few turns will not put enough fuel into the motor to get it started. Midway through swapping the original carb for a Walbro clone with a choke.
