Unfortunately, no pictures were ever taken of the third prototype but it was designed with three wheels.
The third design was welded out of square aluminum.
Above: Tape on wood to layout the second design.
The first design was to weak in the middle and would bend.
This was welded up but never got any further.
Pictures of the first design. This is me 30 years ago.
The first design of the wing. This will be used to control the turning and up and down.
