Speedybee F405 V4 Flight Controller for 3-6S FPV 4-5 Inch Racing Drones

The new V4 stack circuit design has been significantly optimized, with PCB copper thickness upgraded from 2 ounces to 3 ounces, and MOS transistors upgraded to higher specifications. The continuous current of a single circuit has been upgraded to a total of four circuits of 220A, and the peak current has been further increased to 280A for 10 seconds. Easily drive any of the most violent 6S/4S motors. Add aluminum alloy heat dissipation fins to quickly evacuate MOS tube heat, making the output of the electrical regulator more stable.

Using well-known brand power supply chips to independently power the onboard ICM42688P gyroscope, the anti surge capability is increased by 320%; Equipped with a 100uF ultra large filtering tantalum capacitor, it protects the gyroscope data from power interference and allows you to fully experience the pure beauty of flight!

The F405 V4 flight control supports 8-way motors, so it can be used on your X8, Y6, fixed wing, and other models that require more than 4 motors. Now open the SpeedyBee app and adjust the parameters immediately.

The package contains: - SpeedyBee F405 V4 Flight Control x 1 - SpeedyBee BLS 55A four in one - electrical regulation x 1 - 35V 1000uF high-frequency low resistance capacitor x 1 - M3 nylon hex nut x 5 - M3 silicone rubber ring x 5 - M3 * 8mm silicone sleeve (for flight control) x 5 - M3 * 8.1mm silicone sleeve (electrically adjustable) x 5 - SH 1.0mm 8pin 15mm flat cable (for connecting to flight control and electrical control) x 1 - SH 1.0mm 8pin 75mm flat cable (for connecting flight control and electrical control) x 1 - M3 * 30mm hex socket screw x 5 - For DJI 6pin flat cable (80mm) x 1 - XT60 power cord (70mm) x 1

We suggest connecting the TX and RX of the EL RS receiver to the T2 and R2 of the flight control. When using for DJI sky terminal, some ELRS receivers may not be able to be recognized by flight control normally. If this problem occurs, you need to disconnect the SBUS signal cable of the sky end cable from the flight control. You can use tweezers to pick out the SBUS cable head from the 6PIN cable terminal (Alternatively, cut the wire directly) and properly insulate the wire ends.
