Hi

That seems a bit complex.
1/ You'll need to switch something to make the plane record the PF side, as it changes. What about "quick" changes? "My aircraft" (time sensitive situation): do you...

Hi wallybird7

Never did I say that one can recover an out of control plane with trim alone.
And I do agree that the (auto) trim seems weird, based on the may 27th note : why did it go (almost)...
