Hacker C54-2Y L Acro 6.7:1 Competition Geared Innrunner For F3A_1

Details

C54-2Y L Acro 6,7:1 Competition
The C54 4 pole inrunner is one of Hacker’s newest, first introduced at the 2015 F3A World Championships.
4 pole rotor design offers improved torque for more power at lower overall rotor RPMs.
Hacker engineers meticulously optimize the design and materials to decrease weight. The cooling fan has been reworked to maximize cooling.
The goal for C54 motors was to spin a larger prop than the C50 of similar size
. More power is always better, but sometimes similar power for 80 grams less weight is preferred. C54 can save up to 80 grams over a 2 pole geared installation!
Always use E-Calc to confirm your choice of motor, prop and batteries is right for you.


Hackers R&D department has made another quantum leap developing the all-new C54 Acro Competition motor. Many detailed innovations have finally resulted in unmatched high standard in design, quality and performance. Our competence in electric motor simulation of both, the magnetic flux, as also with regard to the mechanical
design, lead to an entirely new 4-pole motor concept. In conjunction with the robust and precise Acro Competition gearbox we achieved an unreached power to weight ratio.
