I've been flying my ucd 46 for a week or so and love it. Saito 72 for power with cg at 5 3/4. This cg is "as built", with no weight added anywhere. Pitch was a bit sensitive at this cg so I reduced the elevator throw to soften it up a bit...so far so good.

This is my first cowled aircraft and the engine seems to run extemely warm. I'm wondering how much of the bottom cowl should be cut away to allow for proper cooling?????

FYI...the inlet opening is 2 1/4 inches.
