I'm working on my HH-60 Jayhawk mechanics and there is slop in the links. By the time the movement gets from the swashplate through the bellcrank to the servo arm, it is quite significant. The slop is axial, not radial. Has anyone found a suitable replacement, (servo links aka ball links)?

Roban mechanics ball links have too much slop? Where did you find replacements?

Howars01 I'll report this to the Roban factory tomorrow afternoon. We have them working through a few feedback items that other customers have sent us.
Would you be able to post a photo of the offending link? Or is it all of them, on both ends?Live Q&A every Tuesday and Friday at 9pm EST on my Twitch Livestream

Hi Alpha,
It's all of links except the #2 linkage rod. I did order a bag of links(RBN-60-026) and uniball set(RBN-60-036) to see if maybe I have a bad batch. All 20 of the ball links were "sloppy" and all of the uniballs mic'd out to 5mm. I can post a link to a short video this afternoon.
Thank you

On the Roban Facebook group, a lot of guys have been using SAB ball links for a tighter fit: https://www.amainhobbies.com/sab-gob...0066-s/p240260

One of the servo rod linkage (elevator) in the middle needs to be elevated using a longer type of steel ball with 3mm thread. This has to be noted because if we dont use those there will be binding with the aileron rod links and that spells trouble.Our plastic Linkages are fine and had no issues with them.
