I just got a Hanger 9 Arrow with an evoloution 46 engine and radio at a price I could not turn down I have always run OS in the past and never considered an Evolution engine but now I have one.

The engine with the 3 bladed training prop sucks[:@] It runs very well but power is almost non existant, long takeoff roll that barely gets out of the grass, and almost no speed in flight. im hoping that is just the prop causing this poor performance.

I want to put an APC on there, does anyone know which size APC gets the most performance out of the Evo 46 ???

Thanks !!!!
