1. Battery type: lithium battery / NI-MH battery 2. Battery low -voltage protection mode: When the voltage reaches low voltage protection, the throttle is limited to only 40 %. 3. Early angle: Divided into low, neutralization. Generally, low advanced angles can accommodate more motors. However, because the motor structure is completely different, try each angle in advance to achieve satisfactory driving effects. 4. In order to improve the speed, the forward angle can be set to a high -level angle. After changing the angle close to the angle, it is recommended to test each other on the ground 1. Ensure that ESC is the highest quality and high reliability 2. It can withstand higher current 3. It can set up throttle strokes, compatible with various remote controls. With a smooth and delicate feeling of speed control, first -class linear speed adjustment. 4. The maximum speed can reach 210,000 RPM (2 motors), 70,000 RPM (6 pole motors), and 35,000 RPM (12 string motors). ) Class The above software packages, other products are not included.
