RE: which prop: APC or Master Airscrew
I use both and Zingers if its wood. I use MAS or Zingers on my more scale aircraft and APC on any performance aerobatic scale or not. APC seams to have a lot more of the lower pitch props for snappy performance but I used a 11x9 MAS with an OS 50SX on a 40 sized sport trainer and it was flying faster than the monocoat could keep up with. So It really depends on what you end up liking. I actuall own Fords and Chevys as well.
