I ordered 2 custom coax cable assemblies in the early afternoon, and was shocked when I was notified they shipped later that day! Great service!

Thanks for being there for us small plane owners. It has never been cheap to own a plane but as our planes age it is getting harder and harder to find parts for upkeep. Good fast service also.
