We have raced (up and down) several times against a NACRA Inter 20 at different conditions and it appears that our Capricorn is superior upwinds but usually we are get beaten downwinds. Do we have to live with that? In a F18 field we usually doing very well downwinds.
Typically in my neck of the woods (Texas) the I-20's get thrashed by the top F-18s both around the cans and distance racing (unless it gets really light).
