You folks have convinced me to try ball link connectors in place of or in conjunction with screw lock connectors. I see Tower lists both 1/16" threaded studs and 2-56 threaded studs. Which fit the holes in servo arms and throttle arms? Which is larger, 2-56 threads or 1/16 threads, and/or what is the decimal value of 2-56 threads? I believe 1/16 would be .062. Thanks, guys.

2-56 is slightly bigger than 1/16. I think it's about 5/64, but it might be closer to 3/32.

1/16 = .0625
5/64 = .078125
3/32 = .09375

The factory holes in servo arms are usually 1/16.

The 1/16th will fit nicely in Futaba servo horn holes.

IIRC, JR horns have slightly larger holes. For sure, if you use the 2-56, you will have to enlarge the holes in either. That's not necessarily a bad thing, but be aware of it.

You definitely wont regret using the ball links, it makes for a much nicer installation, and less chance of binding on your control surfaces.

Get the threaded ones and get yourself a 2/32 tap to tap the holes in the servo arms. Much better fit that way with absolutely no slop.

[size=2]Can a ball-link be used for a nosegear control linkage?

I dont have anything that has nosegear, but I would assume a ball link could be used on nose gear linkage just the same as on the other linkages.

Thinking you may have meant 2x56 tap?

You are correct Bruce, sorry for the gross error.
