@kennykingcodes you mean when you do motor tests - they works, but when you disconnect -and try to launch via RC control - motors don't react?

In fact time to time I have the same issue:

FC: SpeedyBee F4V3, SpeedyBee F405 Wing

1. Reciever is ok
2. Mixers is ok
3. Outputs is ok (outputs are enabled and motor test is ok when device is connected by wire)

When we try to connect by RC control then 1 motor or all motors don't launch

Could be fixed by flashing firmware again

Actually I came here to review maybe somebody else have the same issue

Do you have an OSD?
If so, put "system messages" on the OSD and you'll probably get some useful information.
