I can't leave well enough alone. It's 66" wide, 52" from the ground to the top. I cut some masonite supports which will be 1/8" aluminum, and used a piece of cardboard for an end plate. I haven't decided on end plate material, could be CF, FG, lexan, aluminum, whatever.

I've thought of that too. If I think crosswinds are really causing me problems I'll cut the end plates down.
My other thought was, on an a/x course you don't spend much time going in any one direction for very long. So any crosswind effects will be short lived. |

My other thought was, on an a/x course you don't spend much time going in any one direction for very long. So any crosswind effects will be short lived. I doubt crosswind sensitivity will be a big issue. In the pro racing ranks, when teams are allowed to run large end plates, they do. THese days most of the sanctioning bodies limit end plate size (e.g. ALMS). Check out this URL on mulsannescorner.com explaining why it's good to have large end plates. In addition to helping to self-correct if you get sideways (the end plates act like rudders), they actually increase the wing's effectiveness even in a straight line! http://www.mulsannescorner.com/wingendplates.html |
