  1. F3_EVO_Brush V2.0 revision is out of the F3 EVO SP RACING based on is based on a SP RACING F3 EVO firmware 32 brush flight control.
  2. the flight control support 1S (4.2V) and 2S (8.4V) power supply, 2S power can bring flying experience more violence
  3. using STM32F303CCT6 + MPU6500, advanced hardware platform F3 guarantee more stable flight
  4. with a large current NMOS transistors, operating current of up to 10A or more. Each machine is equipped with freewheeling diodes.
  5. support for PPM, SBUS, DSM receiver input signal.
  6. with battery voltage detection and buzzer interface.
  7. PCBA dimensions are: 22MM * 32.5MM, PCB thickness: 1.2MM.

Considerations before applying power: battery voltage selection, the default shipping is 1S (4.2V); 2S first need to disconnect the short contacts 1S, 2S and then connect two pads short. Prohibit the same three pads shorted together.

Receiver configuration:

  • DSM DSM receiver soldered directly to the interface 3.3V, GND, RX3, CF the software configuration UART3.
  • PPM and SBUS receiver welded to the UART2 GND, + 5V, RX2 above, SBUS signal CF in the software configuration UART2.

 Packing Include :


  • 1 x 90mm Frame Kit
  • 2pcs CW, 2pcs CCW 720 Coreless motor
  • 2 pairs propellers(balck+white)
  • 1 pcs F3 EVO V2.0  flight control
