I am working with a pixracer and a Qbrain 4x25A ESC. I tried doing the ESC calibration through QGroundControl but got the message "calibration failed timeout waiting for bat". I measured the voltage across the battery pack and it seems ok.
I haven't configured the RC because I don't have the receiver yet. Should I configure first the RC? Or should I be able to do the ESC calibration right now?
Thanks in advance and apologies for opening two threads in such a short timeframe.
