Bazel hold.
We are installing a full G3X system and have not flown it as of yet, but we did look at this question and left the radios and audio panel a little hi or long from the panel face. I like being able to put your fingers on the bazel and use it to brace while using the units in the panel. The GUD-460 has a good frame around it and that bazel seams to work well for that holding or bracing. The 305 auto-pilot also stands up a little from the panel and works to brace your hand, so we did the same for the stack-up. It will be interesting to see how it works, but it has to be better than bouncing around in a spam-cam. Yours. R.E.A. III 380888
