Hacker A50 12S

The A50 series motors are designed to for the very popular .46 to .90- size class models. Intended as a direct replacement to power your model with quiet and clean electricpower. Engineered to deliver high power for sport and scale airplanes weighing 6 to 13-pounds (2,7-6,0 Kg). Extreme perfomance can be achieved on .46 to .60-size 3D airplanes up to 8,8-pounds (4 Kg), or models requiring up to 1600 watts of power. The 14-pole Outrunner type design creates MASSIVE TORQUE, therefore larger direct drive props can be used without the need for a gearbox. This motor features Oversize bearings, Curved Neo-magnets and High efficiency stator design. Additionally, you will find a Special Large Concentric bearing located in the rotor to support the rotating mass during extreme 3D-manouvers. Propadaptors and mounting screws are included.

The new V4 Series A50 Brushless provides increased efficiency. Through a newly designed rear end plate and the improved fan a higher power throughput is possible and the continuous load is again improved.
