Not mounting the canopy is obviously a money saving item, also everyone has their preference, from screws to quick latches (to tape). The factory does a good job in the belly pan alignment so I wouldn't have minded them doing the canopy as well, however they attached it
The rudder tray I agree should be in place. No big deal if we were installng it in the main canopy area but it is behind the canopy. See post #24 in this thread. The tray is oversized and difficult to install. I almost split the fuse with a trial fit. This should be installed just like the other internal fuse parts during construction. Much easier to install in one hlaf before putting the fuse halves together.
Please weigh your fuse parts and see if they differ much from mine (Beginning of this thread). The weight is fine for glow but just marginal for electric. I build light and chose many lighter items for the build and still came in a few grams over. The wings are actually where weight could be saved with standard foam/balsa construction. I like the hard surface of the composite wings however.
Good luck with your build it actually goes together pretty quickly.
