Jeff said, "Gyros are heavy and require a vacuum source with a lot of associated heavy plumbing. Mike Stirewalt has his Dynon D2 for sale for a very reasonable price."
I did have it for sale . . . but within minutes of listing it on Vansairforce I had two buyers. I sold it to the one whose email came in first. I can't recommend the Dynon D2, although it worked exceedingly well on the recent ferry flight for which I bought it. The attitude information it displays is dependent upon receiving a GPS signal. It has it's own internal GPS and gyros it's true but for some inexplicable reason if it loses a GPS signal - it happens - you lose your horizon. For a low-cost attitude instrument I highly recommend the TruTrak ADI. Used ones sometime show up on eBay in the $500-600 range. They used to make the 3 1/8" ADI which is the one I have in the KR. Currently their ADI that looks like mine is a 2+ inch instrument, which is fine. I just prefer the larger one. They do make a couple newer instruments which do the same thing as their ADI but look a little different. The name Gemini comes to mind, but check out their website. These instruments by TruTrak, the ADI, Gemini and I think a couple others they make are self-contained attitude instruments. They do connect to a GPS puck but that is strictly for ground track (heading) information. The D2 is very smooth and usable. I liked it. However, just imagine being totally dependent on it when in IFR conditions - cloud or on a very dark night without any outside reference. I don't like the idea at all of its dependency upon a GPS signal. Thanks Jeff. Mike KSEE ____________________________________________________________ Experience Threedom $49.99/mo 3 years.
