Flew my new GEPRC CinePro 2" 4K F405 FPV Drone for 4 or 5 times, now there is 0 rssi shown on osd and motors won't start. Checked on betaflight and controls still respond correctly. I'm new to fpv, been flying fpv quads for 6 months now so not super knowledgable about a lot of the technical. Since the controls still work on betaflight I shouldn't have to bind again, right? Could it be the receiver is cooked? It's a DSMX receiver and my other quads are fysky - would there be something about that receiver that could be giving me problems? Thanks in advance for your help.
