Plane is far from following the path mission

Hi  all

I have an homebuild vintage plane (all wood and fabric) were i added two aileron to improve flight performance.

it's 2,4mt wigspan  and it flight very fine  in all modes : manual stabilize, fmwa, rtl... BUT. in auto mode

it doesn't follow very well the desired path  , also if i have a high value  for roll angle (65°)  seems that it doesn't want to turn in short space (and when i fly  in other modes he can !) i made autotune on different level from 6 to 8. I  set  stall prevention to 0  but with no effect on turn radius.... i havo no more idea what to  try to change for improve my plane characteristics in automode.

I attach a parameters and a log

thanks for help

  • I changed navl1 period to the value of 10 (from 15 that i belived was already low) and now the plane follow much better the  programmed path, still some small errors in turns , but much better... i was afraid about lowering that number ... this one for me has been the right number. Just to know for someone  that could have mine similar problem

    Ciao
