ULTRA PRO 2206 2650KV brushless Mot. Lg Graupner S7121

ULTRA PRO 2206 2650KV brushless Mot. Lg Graupner S7121 High performance motor for professional use on multicopter
Hand-wounded, brushless out-runner motors with a special multi-winding for optimal filling degree of the winding and thus optimum efficiency and optimized cooling.

Specially shaped, thicker and larger N52H magnets for up to 30% more torque and good temperature resistance.

Particularly stable and thicker motor shaft. 2206 motor stator installed. The motor size corresponds to the previous Graupner 2806 sizes, 28 mm outer diameter with 6 mm stack height.
Optimal weight/performance ratio.

Less mass inertia thanks to the new M3 prop mounting.
PCB for easy soldering of the connection cables.

Enclosed to the motor are a set of screws and a prop adapter for mounting the Graupner 3D-PROP and also for prevent slipping on the hub.
