SunnySky X3108S KV720 Brushless Motor

The SunnySky X3108S KV720 brushless outrunner motor is specially designed for multirotors, and is recommended for use on aircraft that weigh up to 520 grams per motor. To power this motor, we recommend a 3S-4S LiPo battery and a 20A or 30A ESC. Use 10x3.8, 11x4.7, or 12x3.8 inch propellers for the best results.

We have tested this motor thoroughly, and you can find test data and product images on our website.

At SunnySky, we manufacture motors using only the highest quality materials to ensure that they are built to last. That's why we offer a two-year limited warranty against defects in materials and workmanship. Please note that motor bearings, shafts, and propeller adapters are normal wear parts and are not covered by the two-year warranty. Any subsequent damage caused to the motor or aircraft by these wear parts is also not covered by the warranty. We recommend maintaining and changing these parts periodically for maximum life. 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, choose SunnySky brushless motors for your aircraft.
