Hey Folks,

What's the largest blade I can turn safely with a Century Hawk? I just installed a new Thunder Tiger .39 in it, and power is not a problem with this engine. I ma concerned about blade flex and chopping off tail. I don't do 3D, but I would not mind a bit more blade energy for autos.

Thanks,

ApacheDave

Like he said 550 mm with 30-40 size engine. stretched boom and put a 50 in it you could run 600mm but think it also requires a ratio change

wife says if i'm going to be an addict at least its to a heli
