Before the right canopy slide rail is installed I had to remove the F-705G-R Angle that was installed on the quick build fuselage for the tipup canopy. To do this I had to drill out the temporary pop rivets holding the angle and the F-757 Gusset. I also radiused the F-757 Gusset as per DWG 42 Detail B. Deburred the circular cut on the F-757 Gusset and the rivet holes, clecoed everything together.
