I've been working on the radiators today, and tested my HPLV gun for the first time. Perhaps Monday I'll do the hatch cover behind the cockpit and post some photos. The trickiest part of making the accessory box at the scale hatch location was getting it to fit the curve of the inside of the fuse. One other thing I would do differently would be to create the cover from fiberglass before cutting out the hatch. I'd layout the lines, cover the area with ultracoat, and then lay up 4 or so layers of 5 oz fiberglass that I could use to cut the hatch cover. This way, the hatch cover would match the curve of the fuselage perfectly. I would also recommend using this method for making the gear doors. Skin the bottom of the wing, then make a fiberglass layer that covers the entire area that the retract access and wheel wells will be, then use these for making your retract hatch covers and gear doors and they will match the curvature of the wing perfectly.
