So you guys think something like a .61 fx is gonna be too much for this bird?
Tram,
I have an OS .61FX in mine with a 13x4 APC prop and its fine, I have never flown this plane with a 4 stroke then cannot tell the difference but mine hovers slightly above half throttle. The only noticeable problem I have is the fuel dripping from the carb because of the engine mounted upside down, and the tank too high, this resulted in several dead sticks.
Chris.
