Works as per specifications. Reliable
Works as per specifications. Reliable and adequate for the aircraft.
Had plenty of power, but motor shaft is on the small side, with no replacement shaft available, and it is bent now after a very mild nose skid landing. I am now going to have to buy a Horrizon Hobby motor cause they offer replacement motor shafts.
Exact replacement motor but is much smoother and quieter then the one it replaced
The set up is very easy. The power to drive my 1200mm plane was a breeze for this engine. At half throttle the engine had no problem, and at full throttle the plane was a blast. I would recommend this engine, highly.
Upgraded my version 6 FMS Mustang with this new motor. Wow, what a difference. Now, even at half throttle the Mustang is fast, smooth and stable.
Powerful and great price
Maybe there was a bad batch??
Bought this as a replacement for the original in my Petie 2nd. Third time out it started making clicking noises and every magnet had come loose. It appeared that the epoxy did not stick to the magnets, like they didn't clean any residue off them while building the motor.
