Great all around motor, have upgraded and used this motor in many planes. (Posted on 7/30/2018)
not so good Review by Ronald G. Bouslaugh

we ordered the 650 kv motor and was sent the 500 kv motor. I would have tried it but it was ordered for a friend and he doesn't think it will work. It is impossible to get ahold of Grayson so we were not impressed. (Posted on 6/22/2018)

This is a strong motor for a 13 around inch prop. Was gonna get a tomcat 600kv but this is stock for my plane. And if that one doesn't die, it's going in the Fred Glover P51 (Posted on 4/6/2018)

Great value Review by Todd

This is my go to motor for several of my planes. I run 12x6 up to 14X7 props on it and it performs just fine. It's been the motor I've used in several Multiplex planes (Extra 300, Fun Cub, Solius, Rockstar) I have that call for a much more expensive brand. (Posted on 8/7/2017)
Good bang for the buck. Review by Scott Benedict

I have many of these motors in RC planes, so far without a mishap. The latest one is in a scratch built air boat running a 13x10 prop. No problems. I have one in a 4 pound plane running a 13x10 prop. it gets warm but performs perfectly. I am pulling 36 amps and 559 watts out of it. These motors can be a little noisy, and sometimes have shaft endplay but for the money I can't beat them. (Posted on 7/14/2017)
