After cutting the forward canopy tubes to height, I have further issues with rubbing on the aft skins. Again, the project hands me a circular set of dependencies: you can’t cut the tubes until the frame is fit, you can’t fully fit the frame until the tubes are cut.

Unfortunately, in this instance, I’ll be looking at trimming the skins or some other drastic action in order to get the canopy to fit and slide as it is intended to.
