I don't like the Booya quick release mounts. I just drilled my rear mounts and use a standard RC car body clip to insure the canopy can't blow off. My Canopy is by Fusuno but it fits inside or outside of the stock canopy just like a glove. Both have a thickness of around .027 inch. So, either they copied one of Matt's canopies exactly or they are the OEM for the E6/7 canopies. Mine didn't rub when sitting and not all the time when flying. However, the canopy was flexible enough at the area over the main gear to rub under the right wind, flying direction or whatever. You could see the scrape marks where the gear left Delrin on the inside of the Canopy. It was a 5 minute fix with $15 worth of parts.
