The B50-11S Competition Kv 3000 with 6.7:1 gearbox drive is specifically designed for hotliners, F5B and similar models using 5–6S LiPos.
The integrated high-performance fan cools the B50-Competition motors in the most efficient way. In addition, the running noise is minimized through asymmetrically placed air outlet holes. The external housing design features milled cooling fins for perfect heat dissipation with minimal weight. The B50-Competition is equipped with larger ball bearings than its predecessor, the Hacker B50, which significantly reduces friction and improves service life. A stronger internal shaft with a 6 mm diameter prevents vibrations at extreme speeds. The front and rear bearing plates are screwed in place. The shaft comes with an integrated pinion gear. The increased power output of the B50-Competition motors is delivered via a high-performance gearbox with a 6 mm shaft. As a further feature, all B50-Competition motors are equipped with segmented high-performance rotors made from optimized magnetic material.
