RE: Ball links for Rudder horh?
Bah... the ball links can be used on horns. I'm using dubro 4-40 ball links on the control horns on my turbine. Yes, this puts side load on the horns, but they hold up just fine at 200MPH. Granted, not ideal, but it does work as long as the horn is strong enough to take the side load, and these are (carbon fiber.) I'd agree in that I wouldn't use his method if the horn is weak and bendy, but then again, I wouldn’t use any weak and bendy control surface linkage component in the first place.
