In order to ascend vertically and eliminate the need for a runway, the plane was designed to mimic a helicopter on take-off. Then, once airborne, its propeller would shift through 90 degrees, transforming it neatly into a plane.
Neat on paper perhaps.
Due to low funds the whole operation must be effected entirely by hand. The propeller wound into place, the wings extended quickly, creating sufficient drag to lift the fuselage into place. Then the whole structure bolted tight. If they messed up, if they took too long, there was a chance the propellers force would tear the plane clean in half.
