I thought I had pushed the fair go rule far enough hijacking Macroscien's thread, so I will start afresh. This is the first Fangy fin in Aluminium complete to a smooth finish. 55 degree rake to handle thick weed and burgs. I now need to try it out against some weed and see how the leading edge fares. If it's looking promising and holding up better than G10, the Mk II will be cast and I will see how that behaves...stay tuned :-)

The Mark I above ready for crash testing. The Mark II below will follow if all goes according to plan.
