Lately I have been freaking RocKsim out again with an experimantal flat fin idea. I don't know if rocksim is calculation for the fins on the flat of not.  The mass seems to be a bit heavy also. For the flat fins I have simply reversed the figures. On the plan points screen I make the 1/16" tall and on the thickness data I enter 4 or so inches. I definetly need another opinion on this flat fin business though.
Thanks Again and Enjoy, JP

I've been doing this on a few of my designs, usually for things like canopies and cowlings. However, for an extreme example of this idea in-action, go look at my "Eugene's Axe" plan... |
