ahicks,

I use the Dubro 4-40 Safety Lock Kwik Link on the control horn and Dubro HD 4-40 ball links on the servo end. I use a 4-40 all thread rod and incapulated it with a Mid West carbon fiber tube I get a the LHS. I uses 4-40 nuts to secure the carbon fiber tube in place. This is the way the manual tells you to set up your control linkage on a Wild Hare plane. It's kinda the poor mans way of doing it because it's so cheap but just as strong as any other.
