I seem to have encountered some weird camera gimbal operation with APM 2.5 and MP 1.2.22. I have used the APM 2.0 before with camera stab fine with pitch and yaw. This is the first time I have used all three camera axes - pitch, roll and yaw on APM 2.5. I have configured the pitch, roll and yaw for Aux Ch 11,10, and 9 respectively. All 3 RC input channels for these ACs have been disabled. If I disable pan stab, the pitch stab and roll stab servos work correctly. However, if I enable pan stab, the pitch stab and roll stab servos reactions become exhanged (i.e. the pan stab servo reacts with rolling action and vice versa)! The MNT_MODE is set at RC_Targeting. I tried other modes but the only ones working are RC_Targeting and MAVLink_targeting which have the same reaction. There also doesn't seem to be any docs on the these MNT_Modes so I am just guessing. Shouldn't the pan servo react to a heading (change) as it should be? Any of you guys had the same observation? Thanks for any help.
Since no one has replied to this thread, it looks like nobody has really tried using the pan servo output of APM or attempted to enable it in the code. :(
An additional observation is that the pan stab servo is not responding at all to any motion of the APM. There seems to be no servo signal to the motor since I do not encounter resistance when I try to rotate it slightly. And the pan servo works when I switch it with the others.
Btw, I am using the latest ArduPlane 2.67 code
