the zinger wood prop weighs a lot less than apc and winds up much faster and just as important it slows down instantly rather than gradual. I notice the difference while rolling harrier - at a high angle of attack my diablotin likes to stall or get stuck while rolling through inverted - I pump the throttle and down elevator at this point to keep it rolling smooth. the apc prop seemes like a slow servo, I could get use to it but the lighter wood prop makes it a lot easier because you instantly get gas or brakes at any angle.
