We are the original manufacturer, and we offer wholesale prices for each item.
The flight controller has already flashed the BF firmware before leaving the factory
Support customized functional solutions, OEM production, support for secondary development, and 100% full inspection for shipment.

Powerful functionality:
1: Support full protocol firmware ground station: BF firmware, INAV firmware, APM firmware, Pix or PX4
2: Support secondary development and customization of flight control ground station model names.
