The Hacker A50-V4 motors are 14-pole external rotor motors whose efficiency has been further improved through continuous development. The A50-V4 series features a new rear bearing shield with a fan, which enables even more efficient internal cooling of the entire motor. The various lengths and windings allow for precise adaptation to the model and enable a power range up to 2000W.

The primary application range is for sport and scale models from 2.2 kg to 6.0 kg, and for aerobatic and 3D models up to 4.0 kg takeoff weight. For electric and scale gliders from 7.0 kg to approx. 15.0 kg. The A50-V4 also fits perfectly in 500/550 and 600-class helicopter models.

This weight-optimized high-end motor, weighing just 289g, fits perfectly in model aircraft up to 2.5 kg with 4S or 5S batteries.
