View Full Version : Sonix tail ball link

04-27-2011, 11:51 PM
I'm trying to convert one of my B400's to the Sonix tail. The linkage ball on the Sonix tail is larger (3/16") than what is on the stock B400 (3.5mm?).

So, I'm looking for a ball link that will fit the ball on the Sonix tail and thread onto the 2-56 (or whatever size it is) threaded rod at the end of the pushrod. All the 3/16" ball links I've seen so far are tapped for 4-40 threaded rod.

What have you guys used here?

Doh! Brilliant!

Don't know why I was thinking the Eflite ball wouldn't thread into the Sonix pitch arm.... But it fit perfectly.
