Based on The DJI-intended spot on the S1000 for the IMU (exactly opposite the front of the S1000, ast the back),  am I assuming correctly that ALL users have to set the "mounting" of the thing at "-11" ?

PLease see picture.

Thanls.

(...and of course, and why show a B2 Stealth bomber image instead of a S1000 image?)

I've seen Z at -11 and -12.....are you measuring from the center of the IMU? although I don't think 1 cm would make a difference....This is what Im running with camera and gimbal:
IMU:
X -9
Y 0
Z -12

GPS
X 0
Y 0
Z -30

I heard from someone that the "Z" reading meant nothing, because the whole drone is moving along the same plane, and the variations in the "sideways" COG are un important.  He suggested setting the Z at (e.g. "-9" when NOT carrying a full 6 pound payload, and leave it at -9 even WITH the 6 pound payload attached.   Not sure if he is correct...

measure from the center of gravity (usually where the GPS puck on an A2 is) back to the center of the IMU. So...-9 would be fine either way

Many thanks for the response.

I am looking for signing for my custom data with SHA256withRSA (2048 bit key) digital signing scheme by Mavlink 2.0 signing so my question is can I digitally sign the A2 pull the flight logs from the fc and can I upload the pre-planned mission.
