A short slide show about how to upgrade a KingKong 95GT quadrocopter.
Probably also suitable for the 90GT/110GT.
We're adding a low voltage (or rx signal lost etc.) beeper and we get a full featured OSD by the upgraded omnibus STM32F4 flight controller.
The F4 flight controller is way more performant than the stock F3 flight controller, 8K/8K gyro/PID frequencies in combination with DSHOT600 ESC/motor protocol work fine.
It's recommended to use at least BetaFlight 3.1 firmware and also to update the 4-in-1 BLheli_S ESCs to the latest firmware version.
