That's the spirit, start at the top & work your way down! I usually scratch build as it gives me the most pleasure & challenges my model was my first attempt at an electric scale model. I was building an IC powered B-29 when I first suggested to my scale buddys I was thinking about an electric B-36 even bigger than the B-29. As they were still convinced the B-29 would not fly an electric model was science fiction.

My main U/C legs are piano wire with a coil in it so little twisting motion is transferred to the undercarriage mounts although the legs bend a bit on bad landings. My wheel bogies are very simple & as narrow as possible to fit in the thinner than scale wing. Even so I had to make the gear doors more bulged than scale. Check the photos of the full size, there are blisters on the top surface of the wings for the undercarriage as well. - John.
