Hi, I'm fairly new to the world of racing drones but I've hit a wall! I'm using a flysky-i6 transmitter with an FS-IA68 RECEIVER. It's been working without any issues until today. It binds without any problem, the flashing red light changes to a constant red and the transmitter shows the voltage readings etc. Unfortunately thats all it does! I can't control the drone and it's not showing up on betaflight. AFHDS is switched on as is PPM output, VTX displays a clear image so I'm not sure how to troubleshoot this. As far as I can tell the fc works fine, I can still test motors manually on betaflight manually. Any suggestions would be welcome. The fc is an Omnibus F4 V6
