what Bill said...

These threads always crack me up. What we RV types
forget is that the O-320 was designed to lift four people and we question if it is enough engine for a light and small RV that will only haul two people.

PS: If my bomb load under my wings (you did install hard points right?:D) is not adequate, I will upgrade to an o-360 on the next iteration of the -9A light attack aircraft....
