I really love your "outside the box" building style and always look forward to every post. The undercarriage is looking very good.

Two comments: 1) You will almost certainly need functional cross-bracing on the undercarriage "V-structure" so you need to think about where you will attach the wires and 2) while the brass pulleys on the wing warping arm look great I think that really needs to be a second arm instead of pulleys. That is, there are pulleys on the top pylon for the closed-loop system but the wing warping wires are attached to an arm on the bottom.
