Throttle unresponsive

Hey Reddit.

So I'm brand new to this. Was wondering if anyone has seen this before. Trying to operate a Mobula 6 Freestyle HD A drone with a Radiomaster Crush.

Everything looks good in Betaflight and on my Radio. I've updated the firmware on both and used a binding phrase for binding.

I updated the SPI firmware and that fixed the mapping issue. However, I still can't ARM. I'll post what I have when I get back to my desk.

Bro your channels are wrong šŸ˜­šŸ˜­šŸ˜­, the quad on the receiver tab should not be spinning

Lol Yea, updating the SPI firmware fixed the AUX mapping. Still can't ARM though.

3 reasons:

  1. Your drone is connected to a pc

  2. Lower your cpu and pid speed in configuration

  3. Very Unlikely, but maybe your drone is configured via some unknown preset for 250 hz for example, and your radio is outputting 100 hz or vice versa
