Great Motor

Got this for my FMS Red Tail Mustang cause the stock one in it was a little slow. If you want a faster mustang I would highly recommend this motor.

Replacement motor

MRC sent this replacement motor to replace the bad one that came on my Freewing P-51 Old Crow. So far it has been performing flawlessly. So far I am very satisfied with this motor.

Big improvement

Just changed out the stock motor and ESC from the FW Mustang "Iron ***" and WOW!!!! what a big improvement on the top end speed. Much Faster. will also handle the 4 blade prop as well, but is much better with the two blade prop and more efficient. Highly recommended upgrade!!! Motor and ESC change out took less than 5 minutes. Took an already great flying plane and just made it better. This could easily be added to the FMS planes as well Note: you will also need to upgrade the ESC to something 85A or bigger. I chose the Geko series 85A ESC from here. OUTSTANDING ESC.
