Where can one get 2 or 2.5mm stainless steel control rods? Looks like QuickUk don't have them anymore.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Hey Mike, is there a particular model that you're needing them for or are you just looking for plain non-threaded rods?

jbjones,

I'm looking for already threaded rods. These used to be available from quite a few of the online shops like Ronlund, Heliproz and QuickUk. I suppose with the closure of some of these places it's no longer as easy as it used to be.

I understand. It's a shame our go-to guys like Ron are no longer there. But, we have to rely on ourselves now. Ask the model boaters...they will know. No hobby shops support them, but yet they drive on.

So, what do you need my friend?

Bike spokes

Get yourself a DieTap and make your own stainless linkage rods. That how we used to do it for the MA linkages that were a little flimsy before some of the more modern MA birds came to market. I'm talking pre-1099 if your a MA guy you know.

Bike shop, McFadden machine tool shop, Mcmaster or Graingers and giter done!

Have a good Thanksgiving.

I have spoken with Lunsford tech people, and was told they don't make turnbuckles less than 3mm in shaft diameter....as steel is stronger than titanium below 3mm.

There are some oriental manufacturers....Lynx is one, I believe...that make turnbuckles for 450 sized helis.....but for larger helis, the link lengths are too short.

One just has to Google until your fingers fall off.....

True, they dont make smaller. Many rod ends can accept the 3mm though. It would really help if the OP gave a little more info on the model and use.

Hi Guys, Happy Thanksgiving too you!

I'm restoring a GMP Cobra. I'm using QuickUk ball links which are the same dimension as the Rocket City ones. I have quite a few QuickUK rods in my inventory, however, I'll be needing additional sizes for future projects.
The stainless steel linkage rods on HobbyKing's site have a right and left hand thread. I thought this a bit odd as there's no hex or method for rotating the rod after assy.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Try this technique....

Get a wooden clothespin...or two...

And a pair of vice-grip pliers.

Put the steel link in the clothespin....and adjust the vice-grip pliers
to really "bite" down on the clothespin.

This will keep the link from rotating as you adjust/twist the ball link on....without damaging the steel link.....

FWIW

EEngineer,

The basis for having a linkage rod that incorporates both a left and right hand thread, is to provide a means of adjustment without having to remove the links from their balls. In order to do this, the rod would need to have either a hex or similar to permit rotational adjustment of same.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Tap & Die set as has been suggested above, You can thread your own and save wasting time looking for pre-made ones. Works out cheaper too.

I've got this set - the dies are 2mm, 2.5mm and 3mm.

But, there is a difference between a thread cut by a die....and an extruded thread....

But, with a plastic link end, it wouldn't much matter.

Cut threads

Just run the spoke through two times and your good. Every bit strong enough for anything we do with the linkages. Never look for a linkage rod again, also you can put the rod on a low speed drill and speed the process also you can make the depth of threads that tell you ahead of time that you have bottomed out on your ball link. You know when you over drive the link in the ball link. Well measure the max depth and only cut to the depth you want there by eliminating the chance of going to far and damaging the ball link.

They are also lighter than some of the fine steal that is used in kits.

Also grab a bottle of cutting oil.
