I clean the servo with alcohol, stick tape on it, put a puddle of medium c.a. on the other side, and stick it in place. the c.a. coats the wood and it sticks at the same time. fastest way I've found. a coat of epoxy works well also, but the tape falls off bare wood! so something must be used. I've used servo tape since late 70's, and it always worked when glued. Had to use it in the early hornets, as I had to lay fut. s-28's on their sides to get them to fit! mounted a lot of kps-14's with it. had a freind that had those with the servo lugs cut off, as he always taped them in! Of course, we were about 15 then, and did some bonehead stuff! you know, the coathangar gear, and pulling all the shims outa our 049's to get "more performance"- and then they were a pain to start!
