Desk for the D4 breaks down more if you want it to – overhead/top/two side cupboards and centre drawer.
Take the side steps off the fuselage – use jacking castors on the base and the fuse/octagon/base will pass through a standard door (may need to unhinge door if not clear opening.
One word of caution – moving complete unit is nose/tail heavy and prone to overbalance. I used specially built support dolly to nose and tail to cross rough ground.
Different weights/lumps of other trainer types (basically ANT and D4 has sliding cockpit roof – D2 hinge up like Bf109)
