That reminds me of how I "tared" our camera servos. I plugged them into the RC
before building the camera mount, then set the pan servo to PWM=124 and the tilt servo to PWM=144. (These are the default center values in Kevin's cam code.) I then removed them from power so they'd stay in that position and built the cam mount.
Since you already have the mount built, if you think setting resetting the servos to allow more useful angle might help, just remove the retainer screws on the servos and lift the "PT-HORN" off. Then you'll probably want to remove the whole PT-MNT piece also. Then run code to set the PWM values I said above, remove power, and add the PT-MNT at whatever angle you want and rotate the PT-TILT-BRK however you want. Press them back onto the servos and replace the retainer screws.
(I got the "PT-HORN" type names from the official Mount Assembly instructions)
