FT Gremlin firmware and setup betaflight 4.1 Femto F3 FC ?


New member
I don't know if this is the best place in the forum for this question.

Is the femto F3 FC supported by beta 4.1 Just wondering what ESC flash and protocol, FC firmware everyone was using?
The issue I am having only motor 2 starts up the other 3 motors just kind of jump and twitch. I have tried a few different flashes since I can't go back to the beta 3.3. My gremlin is also setup for turtle mode and worked great before now . I thought maybe it was and fc issue but same response with all modes I also swapped to a new Femto with the same results I'm sure it is a setup issue. Thanks in advance
