At this point I consider the project completed. I have been flying my AXN Floater for a while now without any issues. The 30A mag switch works without any problems. It is nice to connect the battery and place the cover then just touch the magnet to the fuse to turn on all of the electronics. After landing I just pick up the plane and disable the power with the magnet. I don't have to open the cockpit and disconnect the battery until I get it back to my workbench. Very nice.
This summer I plan to install the 30A switch into two other powered gliders -- I don't expect any problems. I also want to install the BEC version into at least one unpowered glider.
