Default 645 servo setup

Can you guys explain how you attached the ball joint to the steering link on your 645 servo mods?

I just opened the hole furthest from center on the standard, single sided arm that the servo came with and it's worked fine for me.

I was thinking of using the plastic arm that came witht the 645, but I was wondering if its best to put a nut on the ball joint, or just thread it into the arm. Anybody know the thread size for the ball joint?

I would nut it either way.

Just my IMO.

You can use the stock servo horns that came with it, and cut one of them down to make the right horn. Or you could just get an alum. one for like 3 bucks

You will strip the plastic horn out! I started with like you said putting the ball onto the horn, but your better off just ditching the whole thing and making a new steering rod.

I used an aluminum arm with the stock ball. Placed some loctite on the threads and put it in from the back.
