I start the drone as usual with FM2. But no response from the drone. I put FM1, then lights flashes and I can trim, emergency... Put FM2 or FM3, nothing happens. How come FM2 is now disabled??? Any hint?
Do not change the 1000000 value - it is there to workaround 100m altitude limit bug in sketch. If you change that to 0 your altitude will be actually limited to 100m.
If you can trim in FM1 it means you have you 3-pos switch setup incorrectly on DX7 and your LAND/FM1/FM2 positions mixed up as triming can only be done in LAND. Fix that in SETUP mode first.
EDIT: Also make sure your throttle stick is centered when launching.
