HAHAHA! Thanks, I enjoyed your reply! Thank you. Can I comment on each of your points?
1. Yes, compass is in the leg. My bad; I am wrong, sorry, had in mind barometric sensor was in the other leg. But where it is, is irrelevant.
2. Good description of IMU! Did you read it?? Quoting "When used in orientation sensors, the term IMU is often (wrongly) used synonymously for
Attitude and heading reference system." You see,, an IMU does NOT include altitude control. Altutude sensing by barometric sensor is totally separate from IMU function.
3. Sorry to burst your bubble.
In discussing IMU and cooling, I stand by my premise that adjusting it at a wrong (cool) temp that is not reality while actually flying, is nonsense.
