B50-8S Competition with 6,7:1 Gearbox
area of application: Hotliner, F5B…at 4S LiPo
The integrated high-performance fan cools the B50 competition motors in the most effective way. The running noise is also reduced to a minimum with asymmetrically positioned air outlet holes. The outer housing design with milled cooling grooves offers perfect heat radiation with the lowest possible weight.

The B50 competition motors are equipped with segmented high-performance rotors made from optimized magnetic material.

The B50-Competition is equipped with larger ball bearings than its predecessor Hacker B50. This significantly reduces friction and optimizes service life. In addition, a stronger, internal shaft with a diameter of 6mm prevents vibrations at extreme speeds. The front and rear end shields are screwed together. The shaft is equipped with an integrated pinion. The increased power output of the B50 competition motors is guaranteed by a high-performance gearbox with a 6mm shaft.
