Hi
I built an RV7 panel using an AFS-3500 EFIS with engine sensors, GNS 430, Trutrak autopilot from AFS all powered through Vertical Power VPX pro. Everything works beautifully as expected.
I'm concerned about having some kind basic back up flight instruments. I started with a basic/cheap airspeed and altimeter from ebay. I lucked out on the altimeter but found the airspeed indicator had leaks when I went for the IFR pitot/static test. For $170 an inexpensive new Falcon non-tso'd airspeed indicator from Spruce can be had.
The one that has been giving me frustration is finding an inexpensive but reliable electric attitude indicator for less than $500. Truktrak has them for 1300, occasionally something used might be found for 700-1000 on ebay. Anything new is 2000.
I'm just looking for something basic and simple to get me out of the clouds should there be a failure of the EFIS or electrical system. I have been experimenting with a Samsung Android S2 phone with a attitude app. Sensors seem to be slow to react. Considered experimenting with an IPhone.
Anyone find an inexpensive solution to the electric backup attitude indicator?
