This has probably been asked before, but I can't seem to find it.
So I mistakenly bought a 9 x 6 "E" prop (packaging says "thin electric", manufactured by APC), instead of 9 x 6 "SF" (slow flyer).
Will that be OK for my SuperTigre 400 motor?
It is clearly heavier and seems to be much stiffer (blades barely bend), but it's the same diameter and pitch, so maybe it's OK???
