SunnySky motors sold by Buddy RC are manufactured by using quality materials and built to last. The motors are covered by a two year limited warranty against defects in materials and workmanship.
Motor bearings, shafts, and propeller adapters are normal wear parts, and as such, need to be maintained and changed periodically. Therefore these parts are not covered by the two year warranty, nor any subsequent damage caused to the motor or aircraft by these wear parts.
For maximum life, we suggest to install motors and accessories properly, and put a small drop of oil on each bearing every 10 flights. If phenomena of motor vibration, shaking, roughness, or notches in bearings are observed after a period of use, it is suggested to replace motor bearings immediately. It is the responsibility of the pilot to ensure that the bearings are maintained properly and periodically. For the best overall combination of performance, quality, and value, use SunnySky brushless motors in your aircrafts.

- This motor is a beast. Review by Dj All my reviews (1)
I started this airplane out with the SunnySky X2820 KV800 and wanted more speed and I got way more than I expected. The kv800 really does have all the power I needed, but now I have over kill.
This motor uses about 1700 mah in 4 minutes of hard 3d flying, where the kv 800 used about 1400 mah in 5 minutes of flying. I ran an APC 14x7E prop on the kv 800. Both motors and ESC's have stayed cool to the touch. Battery is warm but not hot.
If you need some high dollar power at a really fair price then you will want this motor. I am sold on SunnySky motors. (Posted on 7/18/16)
