RedFox baby is a high quality electirc motor with gearbox. Its used for F5J models where high performance is crucial, which is one of the reasons its also used for competitions.
This powertrain can be used for models up to 1200gr. The power unit is capable of delivering 500W constant power. The unit has a gear ratio of 4.7:1, featuring 3 planetary gear sets and ball bearings.
At about 900gr model weight, the climb rate is 15 - 17 m/s, and with 1200gr model weight, the climb rate is 11 - 13 m/s. The data is calculated with 3S 500mAh LiPo batteries.
