This is my "ode to early daredevils" piece and is based on the popular vintage film clip of a mulitwinged plane folding in half prior to even taking off.
All the propellers are connected via cables to a central shaft that is operated by a single crank. Props are designed to spin towards each other to offset any gyroscoping effects (not that there's any worry about that). The rudders on each engine are connected via wires to the central rudder in the back (note the winged dutch clog) so that they all turn together.
