Just to clarify, I am talking about add-on fins that go anywhere on the shell. There are many things I want to try with it, I have three different ones in mind...
offset (left and right) which will help with predominantly left/right hand circuits. This is to do with offset tracking - i.e a turning aid. The third is both in one, a 'double' fin, aiding straight line tracking and also doing what I mentioned in an earlier post. No racing for me this weekend, but more time to get these made.
