As Haim said, the rods are a bit 'crisp'. To make it easier to put a Z bend into the rod, and to make it less likely to break, you need to 'anneal' the metal first. Heat the area that you want to bend until it glows red hot, then let it cool down naturally. Don't put it in water or you'll make it brittle again. Then put your Z bend in.
BUT: don't buy these snap connectors, cause they aren't good, from 10 pieces, only 3 are working fine:
Instead of them, my recommendation is:
They are perfect !
These push rods, are they available fully threaded, I use Ball joints each end,if they were avaiabloe fully threaded, I could cut them to length and screw the ball joints on. Or as an alternative is there a solder sleeve that will go over the plain section which includes a thread.
2.0mm shaft 29.5cm long 2.2mm rolled thread 60TPI (0.42 mm pitch) 7.4 grams weight Nice and stiff BUT wont fit standard metal clevis.
These shafts are only good for plastic clevises unless you have a 60TPI tap.
standard 2.0mm shafts are 30 cm long with 2.1mm rolled thread 56TPI (0.45mm pitch) 6.4 grams
I know that. I already have plenty of rods that can accept plastic links. These are listed as M2. M2 is a standard thread type on which M2 nuts and M2 steel clevises thread onto. You cannot even start an M2 threaded nut or clevis onto these rods. They are not M2.
So all I want is for HK to acknowledge that, and to change the listing to say "2mm diam rods suitable for plastic linkages" and delete the "M2 rods ..." but they simply will not acknowledge that, so I hope that people read this. It's not much fun when you have a plane on the bench and you're waiting for the pushrods and they turn up as not the listed item, and HK refuse to acknowledge that they're wrong.
This is not the first case this has happened. I ordered an AquaStar boat motor some time ago, and when it arrived, the bolt holes on the front of the motor had a thread that is NOT known to humankind. I had to make a new thread in order to mount the motor in the boat.
Thanks for the Info, yet another incorrectly detailed product. There are quite a few others, the funny thing is they can take the time and effort to delete complaining comments but not fix the info. Don't know why its so difficult to get the info correct.
In the non threaded end you can use a Z bend, a L bend with a retainer or a clevis with set screws. Its also possible to solder a metal clevis to the non threaded end. If this is a high stress application, soldering one metal clevis to one end and using the threaded end w/metal clevis for adjustments is one very safe way to go. A screw on nylon clevis with safety rubber band(piece of fuel line) is fine if you want something other than the servo to snap in an impact situation. But since we are ta
I use theae on my foamies. Sure they are a bit heavy but you dont get any flex and you can bend them to suit. They are theaded on one end so i can just twist in a 2mm clevis and zbend the other end to the servo.
Yes these are threaded on one end of the rods they are 2mm and the Nylon Clevis 2x29mm fit perfect and dont forget 2mm linkage stoppers for the end with no thread to connect to the servo arm unless you plan to do Z bends.
2mm diamiter and about a foot long i just got these and the clips to go with them there strong and big and there for like a 48 inch or larger plane each rod wights just over 7 grams and thats heavy for a small plane
When are they Back ,,Im so sick of Waiting for such simple Model Parts How can this Be not stocked Permanently ., why ,,When i need simple things,, i go elsewhere , as there not In stock again !!!!!!!!!!!!
Can someone tell me how i can delete this item from my order after having paid. I phoned and there was no answer, i send a complaint at customer service, and whent to live chat and it does not want me to write anything.
well if you can move the servo closer you can cut down the amout you need or you could save and uses paper clips as they are tuff and metal but also light. don't forget that you can get them in loads of colours and sizes
Can anyone tell me which clevises on the HK site will work with these rods and which control horns will work with the clevises please? This is my first time creating DIY ailerons and flaps- do you just bend a small ' Z' shape at the non- threaded end of the rod to hook into the servo horn? Thanks in advance
you can use these on any 2mm clevis from HK such as (Nylon Clevis M2 L23)which are really good. as for the unthreaded side you can do a Z bend or you can use one of these (Nylon Snap-Click style clevis 2x8x23mm)which you only require to do a L shaped bend on the rod. hope this helps
thank you- just to clarify- you mean to use the snap-click clevis for any spare cut offs of the rods where no thread is left for regular clevises for connecting to control horns only or are you saying you can use the snap-click ones on the unthreaded ends to connect to servo control arms as well (if I don't want to bend a Z or L shape)?
Drugos you are very strong :) *genrlst dont take this, (i ordered this by mistake) now i try it to make Z bend on one
and its very very hard to bend this
even if you make z bend they looks ****py i try it and its very hard to bend this rods
Just right for micro servos. Z-Bends take practice to get nice and neat by hand. There are specialized pliers available for 5-10 bucks that will do it for you if you choose. Alternately, solder-on clevises or threaded ends can make a nice connection. A quick and easy one is just a 90 bend and a locking clip, also available here and elsewhere.
The servos work great for any foamy, I have a custom built euro fighter, and the control surfaces function flaulessly, and for a z bend needlenose pliers are great, but any plier is unaccrurate vers. a snap link that uses a 90 degree bend. and is so secure, you shold spend the 3 bucks or less and use them from HK. I will say they do not bind and do not shift, and the consistency of only bending 90 degrees is foolproof, thanks eric
They will be restocked eventually, so strong pushrods, needed electric drill with cutter to cut, could not cut with pliers. See also Push Rod and Sleeve Set (5pcs/bag) PRODUCT ID: OR015-00601 BK too but will restock soon. After Chines New Year.
Your best bet would be to tick the box which says "Send an Email when these are back in stock" HobbyKing then send you an email as soon as they arrive. Saves you from keep checking and you get in early enough to stock up. Please ignore the swelling up comment. It's not true.
So these are thread one end so you can z bend the other. What is I want z bend both ends??? I always get the length wrong. I know I have to cut off the tread but I wish there was some way to adjust the gap without moving the servo?
Try Adjusting travel and endpoints on your Tx for the servo connected by the double Z bends or mount your Servo when you are sure it is in the right place. It will not go out of adjustment until your next crash...
Good pushrods for light work. They are only 2mm thick so they are fine for throttle linkages on large planes or control surfaces on smaller aircraft but I would not trust them to move large surfaces on 40 size models or larger.

1 thumbs up!
It would be nice if you actually stocked these. I have been buying from HK for well over a year, and I don't think I've ever seen them stocked. If they were I would have likely bought at least a couple of setts. They are definatly worth what you charge for them. Thanks for the nice pictures anyhow.

Going on 4 months now, and still on backorder since I purchased these. How much longer? Not IMPRESSED!!!!!!!!!!
