Yep, may take me a while bit I do finally learn something over the years. When I build a plane I have it all assembled while it is in the bones, all the linkage is made up, the gear is all installed, I don't hard mount anything right away, I use the gear to get the CG then hard mount it. The control surfaces are all mounted and working. Then I take it apart and do all the finish work and cover. Some of the servos and gear stay in the plane if they aren't in the way. After covering assembling the plane again is easy.
