Actually I rec'd an e-mail from Vector this morning. They said they would pre-cut CA hinge slots for me at no charge if I requested it at the time of order. Although I like the idea of the robart hinges, I've never used them and I doubt my abilty to get them mounted properly on the pre-beveled control surfaces. As VF used to sell the planes with the control surfaces pre-hinged with CA hinges, tehy must have the tooling set up for this already so they should be perfect!
