This kind of modification is more violent, and the wind pressure is very high. Suitable for customers who require high performance improvement Speed: 35000 rpm; Input Voltage: DC 12V; Maximum current: 24A Maximum power: 380W; Maximum thrust: 1200g; KV value: 3100 Notice:Don`t wiring the turbine directly to Power.This have to connected up Driver ESC electronic speed control.Don`t Let the turbine contact with car iron part(because of other iron part also negative electrode "-") Please operate according to the following operation mode: a. Power off first b. Esc switch knob is screwed to the minimum position. C. To connect dc 12 volt battery. Step The first step is to insert the three-needle plug into the out position of the tester. The white line is on the s-pole. There are three rows of arbitrary plugs in one row, and the knob is set to the minimum position. The second step is to weld the three rows of motor wires with the three wires adjusted by electricity without any color difference. After welding, tape should be wrapped to prevent short circuit. The third step is to connect a DC 12 volt power supply to an electrically regulated red connection positive pole and a black connection to the negative pole. After power on, the motor make a sound, stop ringing after a few seconds, then slowly twist the knob of the tester to start the motor, the normal operation of the wind is from the motor tail discharge, if not to indicate that the motor reversed, the need to remove two of the motor wires to adjust and then welding,then the motor works properly.
