A50-12L V4

The new V4 series of A50 brushless motors offers increased efficiency. Thanks to a newly designed  rear end plate and the improved fan, a higher power throughput is possible and the continuous load is also improved.

Also ideal as a nose drive for large gliders (example: Ventus 2CX, 6m wingspan, 11.5kg to approx. 15kg)
– with e.g. 6S-5000mAh and Prop 18.5×10 (approx. 60A)
– with e.g. 8S-3800mAh and Prop 14×10 (approx. 55A)

Front Electric Self-launcher

Also ideal in combination with the FES Ex UNI8 system (see “Accessories” tab).
