I run iPads with an iLevil AHRS. I cannot trust the iLevil unit, it does the occasional gyro wobble even to the point that it may go upside down on me for no reason, but for VFR it's great, it didn't cost a lot, has ASI, Alt, VSI, ball, compass, G meter etc. U/L, you should have contacted me about it and I would have told you all of this... don't bet your life on it if you need to, even in a bind
PS: I hope you don't have to move those 208's on float out of the hangar to get yours out! (assuming that's what they both are)
