Motor Review

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.

New motor for Ferocious Frankie

After many great flights the motor on my P51 1400mm began to make an unusual noise. Ordered new motor. Did quick easy install and I was back in the air. Love this motor and the FMS P51.

Great power

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.

Increased performance

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.
