What makes this FC different from others?

1. Solder pads are the largest compared to other mini FCs in the market.
2. Proper solder pad spacing to avoid solder bridges and facilitate easy soldering.
3. TVS Diode for Reverse Polarity Protection and Voltage Spike Suppression.
4. Powerful BEC to supply all your electronics.
5. The Pads arrangement is executed in such a way that when you twist the wires of the camera VTX and RX you don’t get any wire overlapping this gives you a uniform twist and clean look.
6. DJI connector on the bottom side, power supply by BAT.
7. Two stages of Quality check to reduce any faulty electronic.
8. No power lines near Gyro to avoid any EMI interference.
