We have a LSA builder locally that has installed them in the LSA's he built. Says they are great little radios. He did mention he had problems matching the mic impedance with his head set. Seems there is little information and the screw adjustment is smaller than a fleas teeny weenie.
This is a belated reply in that I don't monitor this list sometimes for a week or two, and I missed this posting. Anyway, I have one of the Flightline Coms in my Pitts S1C (very noisy cockpit) and it works great. I use an external antenna mounted on the turtledeck.
Installed one last month.. seems to work pretty good. Have not figured out how the ICS works or doesn't work. Might be a wiring problem but not sure. Other than that its well worth the price and easy to install.
