3D Hobby Shop Extra 330LT Assembly Manual Download Page 17

Your kit includes two different kinds of ball links. The top one is used in between the

phenolic control horns. The bottom one, with the integrated spacer, is used on the servo

arm end. 

Pushrods on the 108” Extra are assembled in this way, with a ball link on each end of a

stainless-steel link. Note that the links have left hand threads on one end and right hand

threads on the other. Look very carefully to determine left and right before screwing on

your links.
