RE: Just picked up a GP Big Stik 60! Engine Recommendations?
I have a Hangar 9 ultra stick .60, which is almost the same plane. I have a OS .61fx with some minor mods, and a 12*6 apc prop and this plane has loads of power. It will do anything you want it to. And it is still light and no clearance problems.
I am usually the guy with .25 size plane with a .46 in it, and the stick is not hurting for power.
