Over the xmas break I have a plan....

modify the original rudder, specifically around the stainless part

take a mould of the rudder head from Shy and use the lower part of the blade from Karp

cast my own set of blades, this will be initially done in chopped mat for testing & seeing I've never done this sort of thing before I cant afford to waste it in carbon or Kevlar. I happen to have ~30metres of heavy gsm chopped mat on hand so its "expendable" in comparision to the cost of having to get the carbon or Kevlar cloth

stay tuned
