Today I spent some time building a rolling tailcone dolly out of wood from the crates my wing kit came in and a couple 2x4s I had lying around. With the tailcone on the sawhorses, it is too high to attach the vertical stabilizer and rudder without hitting the ceiling in the shop (low ceilings). I figured it would be easy to build a low profile rolling dolly that was low to the ground in order to get around this problem.
