The Hacker A50-V4 motors are 14-pole external rotor motors whose efficiency has been further improved through continuous development. The A50-V4 series has a new rear end shield with fan, which enables even more efficient internal cooling of the entire motor. The different lengths and windings allow an exact adaptation to the model and allow a power range up to 2000W.
The main range of use is for sport and scale models from 2.2 kg to 6.0 kg, for aerobatic and 3D models up to 4.0 kg take-off weight. For electric and scale gliders from 7.0 kg to approx. 15.0 kg. The A50-V4 also fits perfectly in helicopter models of the 500/550 and 600 class.
This weight-optimised high-end motor with a weight of only 445g fits perfectly in motor models up to 4kg or gliders up to 15kg.
