The YUKI MODEL SUMO-Combo of type B4 is a combination of LiPo controller and brushless motor for RC cars on a scale of 1:10. The controller offers a constant current of up to 60 A with short-term peaks of up to 380 A. It is designed for operation with LiPo batteries (2S-3S) or NiMH packs (6-8 cells). An integrated switching BEC provides up to 3 A current at 6 V voltage, in order to save a separate power supply for the receiver. The controller generates a resistance of only 0.7 mOhm. Its dimensions are 42 x 34 x 35 mm, the weight is 107 g. The motor has a specific speed of 3,900 rpm / V (KV) and a standard shaft diameter of 3.175 mm. Its diameter is 36 mm, the length 50 mm and the weight is 179 g.
