I designed a vtol plane like QuadRanger. Recently, I am tuning the pid parameters in multicopter mode.
According to the method as the website of px4 decripting, I fixed the roll axis to tune the pid parameters of pitch rate control ring in ACRO mode.I set the pid parameters of roll and yaw rate ring zero.However,whatever I increase the p of pitch rate ring with i and d zero,the plane always round down on roll axis.It make me very confused.any one has suffered this?And I didn’t make my px4 board placed on the gravity center,whether is the desperate phenoenon resulted from this?My beloved plane photo as followed…
