Yet another, a third, prototype. “Lettuce” hope that third time is a charm.

Each time it was better...think you nailed it this time. Super tech drawings.

Actually I did not nail it. Further investigation reveals that the left and right cylinder banks must be staggered. The right slightly forward of the left. The space between the rear of the radiator and the cabane struts will not allow this spacing. If I decease the diameters of the cylinders and construct a fourth engine, I can solve this dilemma. However, then the cylinders are too small for me to detail with springs, lifters, plugs, and wires. I am forced to install the engine of the latter Jenny aero-planes. A v-8 with valve covers. Valve covers and exhaust pipes will be a much easier build.
