B50-7S Competition + 6,7:1 Kv 4720

Product description and features

The B50-7S Competition Kv 4720 with 6.7:1 gear drive is specially designed for hotliners, F5B and similar models with 3-4S LiPos.

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 external housing design with milled cooling grooves offers perfect heat dissipation with minimum weight. The B50-Competition is equipped with larger ball bearings than its predecessor, the Hacker B50. This significantly reduces friction and optimises service life. In addition, a stronger, internal shaft with a diameter of 6 mm prevents vibrations at extreme speeds. The front and rear end shields are bolted together. The shaft is equipped with an integrated pinion. The increased power output of the B50 Competition motors is ensured by a high-performance gearbox with a 6 mm shaft. As a further special feature, all B50-Competition motors are equipped with segmented high-performance rotors made from optimised magnetic material.
