I got this drone a few days ago and after turning on NAZA mode, I'm having trouble getting ioc to work. All S1 switches work, but S2 is not. What can I do? Also, is there a way to set up manual mode to the S2 switch?
+1If the switch is not working, as verified in the RCAssistant, it is typically a hardware problem with the switch itself.
You can Google/YouTube for vids on how to replace it. (You may consider doing S1 as well while in there.)
"Manual" mode can only be assigned to S1.
