The AHRS500 would be the best The AHRS500 would be the best choice because of the functions it choice because of the functions it provides and its serial interface, provides and its serial interface, but it might cost way too muchbut it might cost way too much
The tilt sensors would be cost The tilt sensors would be cost effective but there was no effective but there was no indication if they would work at indication if they would work at altitudealtitude
