SunnySky X3508S KV580 Brushless Motor

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.

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.

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.
