I installed an Emax 32 motor GT3520/05. I'm getting 750 Watts @ 50 Amps static with an APC 11x8.5E prop on a 4 cell 3300 Mah 30C Lipo. 60 Amp ESC. the plane weighs 4.9 pounds. It balanced perfect with the Lipo about 1 1/2" behind the firewall. There are no bad traits even at low speeds, it flys great and floats in for landings. The instructions are a bit vague but all in all it was a simple build. I bring this plane with me every time I fly now, it is a very fun plane to fly.
