Whats a good size ball link to use For a Vector 40

Steve: I use the #87 Heavy Duty for 4-40 inserts. Either from Tom Morris or CLC

Steve, So did I. I used Z bends at the elevator horn because of the narrow space back there.A clevis would have worked back there, but I dont really trust them.. I also used the z bend at the belcrank. The ball links are on both holes of the flap horn.I also housed the pushrod(elevator) in a carbon fiber tube to prevent flexing; used JB Weld to seal the tube and ends. Probably over-kill, but better safe than sorry...
