sensors

I've posted a few times and I appreciate the responses.  I'm planning to launch a high altitude vehicle (rocket or glider) that is actively stabilized (not guided ;) using ardupilot.  To be clear, this is a really small vehicle that will fly for a very short time above 100,000 feet and come down via a parachute.  Its not a UAV.

I'm in the process now of building a gimbal motor mount similar to this one - http://www.criscaso.com/images%20exp%20rocketry/Casimiro%20elementi/Gimbal%204%20e%20on%202004.gif

Mine will be smaller and lighter. 

Assuming I have just the ardupilot main board and the 4 horizon sensors....

From my reading it seems like it will be reasonably easy to set ardupilot up in STABILIZE mode.  I don't need or want any other functionality running. 
Would this be done in the events.pde file? 

I presume it will run just fine with no other boards or sensors attached.


Regarding calibration - I am guessing I am venturing into uncharted territory here but on the off chance anyone knows....

I'll do a calibration on the ground which I understand will be stored in memory.  Three hours and 100,000 feet later.  Any clue as to how this calibration will work?  Frankly close is good enough for what I am doing.

    If this is a rocket, the IMU might not be able to withstand the G forces. An IR sensor would work fine however.
    If you reworked the control loop you could get a much faster response than 50 hz.
