I am looking to add a self steering vane on somewhat of a budget. My big concern is not ruining the beautiful lines or drilling holes in my new boomkin. I’m just curious has anyone here made their own? I would love to see pictures of current set ups. 
I have and old Hassler wind van I could let go pretty cheap. Can’t quote a price right now but doubt I will put er back on Jolly D. Let me know how much you were wanting to spend and we might b able to work something out.
