Hati ... go with a 380KV motor and turn a 16x10. That is more fun to fly. No point turning a small prop at a very high RPM. Ideally, you want to match the pitch speed with the speed of the plane and the amount of thrust you wish to have. In a small prop, it will spin like mad to create the thrust, that causes a high pitch speed and if the thrust does not pull the plane at that pitch speed then its all wasted. I hope I am right on this! Hahahahaha ... No more Angels in Singapore and Malaysia, all sold out.
