I designed one about 15yrs ago, the main beam was 4’ long and the fuselage was 5’. You only need the steering wheel, the sail is preset, cause you are using apparent wind , not natural wind. There was 6 of us on an open parking lot...we had so much fun. We all stayed to those measurements, but everyone had different designs
PET3D nice work . Im working on a big one , Im collecting the accessories for it , please can you send me the plan too ? thanks . Sam samarmm68@gmail.com
