RE: BJ Craft - Nuance 120
Terry
The motor is a Purple Power pro series 5065-380Kv, prop is an APCE 17x10 drawing around 80amps at max power on a fresh lipo, the power does fall off slightly near the end of the flight but the Otop is a full 2 metre model and I think I am really pushing things at 6S on this model, however I do like to experiment!

I would think your motor could probably stand the extra 10amps on the 18x10 in short bursts, I suspect from what Andy says this model does not need 2000watts to fly well, that is going to be over 220 watts per pound.
