for my money, if youve got an experimental glider, go for the Dynon
10A flight display. the power draw is low and you get a lot more info
than just an AI.

The spec at Dynon says 8 watts, which translates to 670 mA, which
doesn't sound low to me, at least for a glider. Or is the actual draw
less than the spec? Admittedly a lot less than a mechanical gyro, but
not something I could run continually for any time. I tried to find
the current draw of the TruTrak units, but couldn't. I think they're
better, but does anyone know for sure?

This probably won't be much help, but.....

There is no manual for the Tru-Trak T&S on their site - at least I
couldn't find one, but I did find one for the ADI, which is somewhat
similar. It didn't quote actual drain, but did say that the wiring and
fuse should handle 2 amps.

OTOH, instruments that I actually have the manual for (SDI C4, Filser
ATR-500) both ask for fuses that are rated well above actual current drain.

Has anybody got experience with the Tru-Trak ADI that they can share?
Would it be any better in a glider than their T&S, bearing in mind that
its twice the price?
