naturally was pretty cool to see my arduhexa run a simple flight plan. i used 40 ft for my home and waypoint altitudes, but the heli easily hit 100 ft. quite disconcerting, as it gets small pretty fast.
in all GPS modes, loiter, rth and auto, the heli will climb to about 80 or 100 ft. for example, even if i start the loiter at an alt of 30 ft, the heli will start to ascend.
the pressure sensor on the board is exposed to open air, so would that cause the problem?

Yes, you should cover the pressure sensor as shown in the manual (bottom of page):
