I hope someone will find the solution to this:
Arducopter 3.1 (latest). APM 2.
A try to calibrate spektrum dx6i (ar6200 receiver) transmitter. Calibration goes well, but after this, in mission planner flight data panel shows Prearm: RC not calibrated.
A tried to run wizard many times from the beginning calibrate everything, but at the verify step "have you configured yout rc transmitter" displayed in red box.
I tried both above many times without luck.
I tried to switch off rc prearm check, I was able to fly, everything worked well, but not after a small crash I might have some other problem to find (not able to arm), I wanted to switch off every prearm functions to find the possible problem, but this rc not calibrated error is stil there.
Can you explain, what this alerm really means? There are values (good values) in the parameters, so what this function checks at all?
I don't really like just saying "switch off prearm check" because I want to understand what is happening, why is it?
