If you're talking about making a hatch in the top of the plane behind the firewall, yes, I've done it to two of the US lites. I actually made my hatches on the bottom of the fuse. I carefully marked it making sure I had enough room next to the former to install some small tri-stock. After checking it out, I marked the bottom of the fuse where I wanted to make my cut and using a metal ruler for a straight edge I cut the hatch out with a #11 knife. Using the knife made the cut so narrow that I could use the piece cut out for the hatch cover itself. Cut some tri-stock to fit inside and glue them it leaving enough sticking inside the opening to screw the hatch cover on. Take some red mono or the like and cover your edges and you may even have to sand the cover a bit to make it fit. The fuse of the lite isn't as heavy duty as the old 120 thats why I put it on the bottom. I did it because it was almost impossible to get all the stuff in there for my G26 without a hatch.
