Warranty: 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 aircraft.

Excellent motors

I have these fitted to a HK Alien 560 with 15 x 5.5 props. I am using extended arms on this quad. The motors are fabulous and operate very efficiently. Plenty of lift and I get 26 minutes endurance with an 8000 Mah battery. These run fine on 3S which is what I am using. Can't go wrong with Sunnysky, my motor of choice for multicopters.


I'm running these with both 15x5 CF and 14x5.5 APC props and BLHeli-flashed Turnigy Plush 40A ESCs and could not be happier. My quad is a Tarot 650 Iron Man loaded down with an APM 2.6 including sonar, GPS, FPV, telemetry radio, and a 3-axis gimbal, and even with a heavy 8000mAh 35C 4S battery they still run surprisingly cool.

Unbelievably happy with these motors!! A must have.

I put these motors on a custom built OV3RQUAD and I am so extremely happy. The motors are dynamically balanced and worked as advertised. I am spinning some DJI 15x5 carbon fiber propellers on a 4s setup. The quad is surprisingly quiet and is extremely efficient. I have not run the system to its extreme as of yet since I am still tweaking it. I did however achieve 18 minutes of flight on a 4s 5000mah battery. I fell pretty confident that I should be able to get 20+ minutes. You won't be disappointed with these motors nor will you with any Sunnysky X or V series motors.

High Quality

This motor is of the same high quality standards that all SunnySky motors are made from. It has a lot of power. I am using 14X4.7 inch GemFam props along with these motors. My only real complaint is that the motors didn't come with bullet connectors to plug into my ESC's.
