A better approach would be to build the lightest, most reliably powerful rotary with a 2.85 redrive and then let others adapt it to their planes. Look at rotax- they don't build firewall forward packages, they have a great engine in it's weight and power range and the plane makers are doing the rest. What were the original powersport superlight engines? 13B p-port, with the oil pan mounting flanges cut off, aluminum side housings, mounted with the exhaust side down? I'm sure there's more to them than that, but I think that's what they were, basically. II would have liked to see Powersport make just the engines- forget the whole package- if the engine is light, powerful, and reliable, then homebuilders will do the rest. Just my two cents.
