Very good motor, installed on a funjet with a 6x6 prop, 60amp ESC and 4 cell LiPo. Very good speed, set-up is adequate, light and a bit faster than the original funjet set-up. The downside is that you can only go full throttle few seconds at time, as you will burn the motor, just as I did... Smoke came out in flight and the whole inside of the motor looks like a charcoal! I'm buying another motor just like this and will keep the full throttle shorter.
