Default Turnbuckles

Check out the thread on page 2 just up from the bottom. That said, some of the options listed (sab) are no longer readily available. Kinda spendy, but flybaress rotors sells a kit.

I have these on the slow boat from China that should deliver today sometime.

The issue is the new Goblin links were changed from M2.5 to M3 when they switched from steel links to titanium so they will not work with the smaller MSH links without breaking them, and the Goblin links are the wrong size for the MSH balls.

I even ordered what was listed as M2.5 turnbuckles for Traxxas trucks from an ebay seller, and they were also 3mm once they arrived.

2.5mm turnbuckles are rare it seems, but these should do the trick and are the correct length to work with

Those are the seemingly discontinued Helioption ones, which I got as well, and paid through the nose for.

Forgot to say they are also a little shorter than the stock rods but they are doing the job.

None that I have found, but that doesnt mean they dont exist. I haven't checked to see if Goblin ball threads are the same as the protos despite being a different size ball, so in theory you could use them if they are. The 2.5mm turnbuckles I linked to work, so I stopped searching

The Goblin turnbuckles I ordered have a outer thread size of 2.88mm. I would have used them but I would have had to change out the balls.

I will try the ones from MM, linked previously, with the newer ball links I just got from MSH. I tried to thread the goblin turnbuckles into them but they were really too big to trust drilling or forcing without drilling. I'll update when they arrive.

Maybe I bought the wrong ones from Goblin. I got the 630-770 size. The ball links are too big for the Protos.

Yeah, I think you have to use the regular ball inks that go everywhere else on the Goblin - not the precision pitch links which are longer.

Are the 570 links M3 thread like the bigger models are? Awesome if so as I have a full set of M3 swash turnbuckles that are the perfect length for my Protos.

Ok, thanks because the MSK links do not have enough there to use anything larger. They will crack

I have solved the primary issue I wanted to using the HeliOption 2.5mm turnbuckles for the grips which is the most important for me for fine tuning blade tracking without having to pop the links. The swash links are not so important for me, so I will stay with the stock parts since this is not something that requires any real adjustment after initial setup
