I wish kit manufacturers would NOT design kits so that one must mount tailwheel assembly BEFORE gluing fuselage halfs together. One must then mask off the tailwheel assembly AND the fuselage interior in that area. This can be a real pain.
Kit mfgs frequently say to paint all parts before assembly. I can only do that if the mfgs will make kits with PERFECT fitting seams. Never had a kit like that. Most of us sand, fill, sand and prime seams!
So design kits where tailwheel (or nosewheel) can be inserted AFTER fuselage is joined and painted.
