2 STCK. 7*20 mm 3,7 V 4,2 V 50000 U/min High Speed Mini kornloser Motor für RC Hubschrauber
4,80 €
Motor length: 20MM. Speed: 45000 RPM. Speed: 50000 RPM. This is a rare motor, and the small motor torque is very large, can not hold with the hand ，which is the value of it! We afford all cost if it's our fault.
