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. If you are looking for something certified then you
got to stick with a Attitude Indicator. Lots of avionics and
instrument shops sell them. www.oxaero.com is glider oriented and has
TruTraks for about a thousand bucks.

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?

I don't have the numbers but the TruTrak drain is very low. I am
running my TruTrak from the same 7AH battery as my transponder and it
is good for at least 6 hours. You can also add an on/off switch and
turn it on only when it may be needed, as it starts instantly.

I couldn't find the current draw of the TruTrak on line either, however I
remember when installing it that it draws just under .120 amps (120
milliamps). I have mine switched so it's only on when needed.

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?

I tried one a year ago but eventually had to pull it out because it
wouldn't stay calibrated. The lightness of the glider seemed to make
it too sensitive to bumps, and when I pulled out of thermals it would
be off kilter. Sometimes it would do the same flying straight and
level.

The dealer worked with me to try all the various software settings for
sensitivty and calibration to make it work but couldn't.

I was looking at the same issue a while back and among others ran
across the MGL system:

http://www.mglavionics.co.za/singles.html

It looks very interesting, Craggy Aero is selling this one along with
the TruTrack system (http://www.craggyaero.com/solidstate.htm). I
don't have any experience with it, anyone like to comment on the MGL
system?

There was a similar thread a while back which you can find here (with
no info on the MGL system):

That's the one I tried unsuccessfully last year.

Which one?
