Derek,
I used the JR 3421SA Digitals. Tiny size, light, strong and accurate. They just fit right in the opening already in the rib.

I'm using the remote glow on my Angel's Shadow with no problem except that yes, it's a pain to get the short lock off once it is on. The plug portion is a radio shack charge jack. Once I install it, I'll post more pictures. It's pretty slick and easy to use. It hasn't come loose at all.

I like the idea of the check vavle, but I don't know if I can live with it hanging outside the plane. The cool factor is important after all!

Joe
