Have you considered Phoenix from http://www.o-navi.com/products.htm
It seems to have everything (6DOF, GPS, static/dynamic pressure, servo outputs, and on top of that it is a software development platform of its own). I don't know more about it, than you can read on their home page. Has anybody experience with it?
Anyway, I am working on an (ever changing) UAV autopilot project based on gumstix. So far I have reproduced the results by firstname.lastname@example.org
, and I am able to control 6 servos with a X-box controller.
At present I am making a coanda flying saucer (http://jlnlabs.imars.com/gfsuav/index.htm
) and control it with a X-box controller through a gumstix.
I am still looking for a sensor package. I might go for SparkFun IMU ans GPS.
