RE: Which direction to mount the engine?
Hi,
For what it is worth there is a fellow in the club I belong to that has an old OS Wankle in a 40 sized Eindeker. There isn't anything protruding from the cowl and it flys in a very scale like manner. Just a thought but you might still pick one of these up at a swap meet or e-bay. Certainly a good match for this model.
Cheers,
Colin
