Pitch reversed in 3.53

I’ve seen different posts about this, but the only response I get is “Reverse pitch in remote control”. What I did. But I do not understand HOW can the Pitch be Reversed only by upgrading to the latest firmware. As I didn’t made any other modifications with my config, I think… I did a radio calibration also, but didn’t changed my parameters.

I have to addmit this is very surprizing if you do not pay attention before you take off!

Using Pixracer.

Nothing has changed in that regard with Arducopter firmware from one version to the next.

I believe you, but believe me, for the first time I had to reverse this axis in my remote, and the relative parameter is always on 0 in MP…
