My Align 450 FBL is running APM 2.5 with Copter fw v3.2 which is the last version supporting APM2.5.
On bench, when I switch to Alt Hold, the CP increase to over 12 deg. Is this NOT acceptable ?
Is the CP supposed to remain the same as when mode is switched to Alt Hold ?
I spent a week to try various setting on H_COL_Max (and Mid, Min) without success. The setting of 2, 3 and 4 for H_SV_MAN do not work except 0(Disable) and 1(passthrough) for setting the collective pitches.
I have no problem setting the CP in another ALign 450 (a flybar) running Copter 4.0.5 and managed to have the CP REMAIN THE SAME when switched to Alt Hold.
Can anyone please help to walk me through the proper procedure for the outdated FW Copter 3.2.
