Leonard knew there was enough variables that in certain spots making a mock up was going to be the only solution. When I built mine there was string and duct tape involved.
The practice of mocking up and verification should have been my method from the beginning. For example, the landing gear angle and geometry needs to be built using the actual fuselage measurements and calculated wing leading edge location. With a plumb bob and a level fuselage you can then determine axel position and actual forward angle degree. 12° is an approximation.
Study the plans, make mock ups, stick to conventional methods.
