Ron,
going to give it a shot in sketchup and see how I do. The problem with the ECU is that I used a good quality velcro and when I went to remove the ecu from the plane the little plastic box literally came apart because the velcro was doing it's job. I was able to put it back together and put some electrical tape around the perimeter so it won't pull apart so easily, but thought 1. I would feel better if I could put it in a mount that secured in the plane, and 2. something I could easily get it out of so that I didn't accidentally separate the case. Now it's just a matter of ....Lets see if I can do this. Should not be too hard to do.
