Newly improved X-III motors provide higher performance and better cooling at the same great price point as the original X series motors. X-Airplane motors offer some of the best bang per pound you can find for radio-controlled model aircraft.

Superb new X series III motors from SunnySky have improved heat dissipation, better efficiency and greater power output over the original X series. These are genuine new SunnySky motors including standard manufacturers fittings. We use the 1250kv motor with the optional short shaft in the Big Crack Yak, the Edge 540T and the Revo P3 models from RC Factory and Twisted Hobbys. The 1250kv is recommended for use on 3 cell batteries (3s) with 9×3.8 propellers or similar. If you are careful with throttle management and know what you are doing you can get away with a 10×3.8 or 10×4 propeller but you run a high risk of burning the motor windings and destroying the motor. A lower 980kv version is available which provides adequate power for mild 3D flying in the aforementioned models but the 1250kv variant provides plenty of power and efficiency for its weight class and comes highly recommended for small foamies.

Included in the box with all X2212-III motors:: -

  • 1 x Genuine SunnySky X2212-III outrunner (Choose kv and shaft options before adding to basket)
  • 1 x Prop driver with screws and nut/washer.
  • 1 x Cross mount

The accessories included are the same regardless of whether you choose the short shaft or long shaft version. The short shaft version is more convenient in foamies as it means you do not need to drill a hole in the fuselage to poke the motors internal shaft through when mounting on the included cross mount.

The 1250kv is also an excellent choice of motor for the Flash 39" Reloaded planes.

Recommended setups

For higher cell counts, use smaller props. For larger props, use lower cell counts!
