Hi,
1) I'm installing a DHS pull/pull rudder in my RC Guys Decathelon. I've never done a p/p and not sure how you go about adjusting the cables after installing.

There will be threaded eyes on either end of the Kevlar cables and one end has a ball link, the other will go to a Hangar 9 swivel clevis horn on the rudder.

How do you get tension on the cables? I assume you can't just turn the threaded eyes, as this would twist the cables. Do you detach the ball link from the servo arm, adjust, and then reattach it?

2) Another question:
I got carbon pushrods for my split elevator and ailes. They came with steel ends that will thread into H9 swivel clevises on the control surfaces. If I also have threaded ends at the servo, what fitting should I use? If its to be another ball link, will a nut on the threads keep the rod from self-adjusting?

Sorry for being so ignorant, it's just that all my experience is in 60 size and down.

Thanks everybody!!!
