Brad,

Nudge is doing something totally different than I do. He must have cut all the rails out of my fiberglass conversion piece. Look at my instructions to see how I make a (manual) movable canopy. I work with a spring steel wire around the front edge that locks into 2 holes on each side. The top center rail is just cosmetic to look like the channel on the real airplane. If I didn't put it in then people would have complained that it wasn't there, and now that it is in place they will ask "What is that for?" I can't win.

These sliding canopy rails that are out now did not exist 7 years ago when I started making these bubble canopy conversion kits. I have some now that I picked up from Dynamic Balsa. I'll have to see how they look and perform. Maybe someday I will convert the Spitfire conversion kit over to a sliding rail, but not yet.
