> "I am using a GRT Mini as the control head for a remote mounted Trig TT22 transponder . . ."
Thanks for the suggestion DJ but at $2500 from Gulf Coast (usually the cheapest source) I'm thinking I can find an ADS-B out solution a lot cheaper than that. With the TT22 we're paying a premium for it's very small size and minimal weight. That's a very nice specialized piece of kit, ideal for sailplanes. I'm thinking inexpensive ADS-B in/out solutions will be popping out of the woodwork from now until 2020 and beyond so I'm going to just bide my time and live with Mode C. In fact, having all that traffic cluttering up a moving map screen is probably more of a distraction than a help. I can easily envision it's value however - the L.A. Basin on a smoggy day for instance. I would have to cut a new panel to incorporate the GRT mini so I intend to stick with my original intent of using a portable moving map that can load approaches and talk to the ECO autopilot. (Don't think there is such a critter? Think again . . . details to follow). I'm thinking a floor mount will work well to hold a 7 - 8 inch tablet thus leaving my existing panel intact. I don't think there's enough room between the panel and my header tank for a GRT mini but even if there is enough room, I'd need to do some major surgery. My TruTrak ADI is such a nice attitude and heading instrument to fly with - don't want to tamper with that. Basically, I don't need an EFIS. If I did, I would sure be interested in the mini.
