Cant see Advanced checkbox under Tuning

Hi. I would like to know how to access the advanced tuning tools using QGroundControl. I am using the Convergence Airframe on a convergence RC model. Under Tuning (Vehicle Setup), I do not see the “Advanced” checkbox which would allow me to access the advance tuning tools. Can anybody help. Thanks

Also can anyone explain the difference between “Tuning” and “PID Tuning” in QgroundControl. Thanks

Advanced Tuning is only available with multi-rotors. If you want to know what PID Tuning is I’d search the PX4 User or Dev web site.
