I have been using Hot Racing servo links on my 6s rigs. Here lately I’ve had several strip or one even broke in half. Does anyone know of a better option for the 6s line? I’d like to have a steel horn but can’t find one. What do you guys recommend?
 
Stock has never let me down 🤣
 
I've used stock & the Hot Racing one. Haven't had one break. But there is a metal one, not aluminum, only reason I know, is I have a Redcat basher with one. It was stock.

Actually that metal one may be too flat for a K6. Sits nearly flush against the top of the servo. 6s links go underneath the horn. This would put the link too far away from the bellcrank. My bad. I had to go look, pic of the Redcat

Really pleased with the setup that I made for my Infraction, especially the Promodeler horn. the linkage is a Ti turnbuckle and Yeah Racing billet ends. Time will tell how quickly the wear will set in and develop some slop, but after 10+ packs of bashing it's still as tight as when I installed it. Bashing off-road, thats going to accelerate the wear.
Ironman RC also has a HR knock-off setup..

I also just got the Yeah Racing 3mm end links and titanium turnbuckle to build a link for a car I’m doing now. Good to hear you like the setup, and good to know it’s still tight after 10 packs. I was wondering how the longevity would be. 👍
Thats a pretty sick build you have there, man.
 
Horn Purchased on ebay under a Sharegoo name. 25T with double clamp screws + use of the center post screw.
Link is a modified HR with PEEK bearing sleeves at each end.
It has withstood a 400 in/oz servo and end to end tumbles .... Seems REALLY Stout

I use the Sharegoo one on my Fireteam.

Thx Dan, I am really enjoying it.
Just not the wear & tear... It was so purdy when I finished the build!

Hell I stripped another HR one yesterday. I can say one thing The Perfect Pass servo is pretty damn tough. I broke one horn in half and then the one yesterday stripped.Servo still works flawlessly. I really am impressed and it’s somewhat cheaper than the Raw 500 or the other high cost servos
 
The HOT racing, Sharegoo and like "LINKS" also are a piss poor design.
They assemble them with NO lubrication and they Waller out & wear out very quickly !!!
When NEW, If you Remove one o-ring at each end, push out the screw post/insert & place a daub of Moly paste in there and reassemble there much longer lasting.

Picture is the links I speak of ... The o-rings where secure the posts within the link are clearly visible.
