Love the spring wire retainer on your pushrods! Simple, elegant straight forward method. Thank you for sharing your expertise, always learn something from your videos.
Thanks Erick, not my idea but it's a good one
Into the tool box goes that awesome technique!
If you forget the shrink wrap, it is just as easy to wrap the pushrods with thread about an inch from the 90 degree bend, saturate with CA or epoxy and it'll be even stronger than just using shrink tubing.
At least with 1mm pushrod using a thread/CA joint, the wire will bend at the thread when directly stressed. May not be literally bulletproof, but i have full confidence a servo would fail before the connection. Just be sure to get the 90 degree bend at 90 degrees and all is solid with no slop.
For those like myself, who still don't have a z-bender, this alternative method just simply gives better results.
Great tip, I often forget to fit the heat shrink
Very ingenious. Solves a constantly recurring headache I have with push-rods. Thanks for the great tip!
Excellent, glad to hear it.
Elegant in its simplicity...thanks for sharing Andrew!
You and Ed from EA, come up with some of the best scratch build ideas. I still really like your bent stainless wire, pre loaded and tied of to string for the rear control surfaces for the gliders and lighter planes.
+3000gtwelder Ed is the MAN
Spectacular!!!! This is why the internet exists. Thank you!
Haha, we would we be without the net
I've just come across this video Andrew. Awesome technique, and wonderfully simple instructions - thanks very much. Cheers, Steve.
Just have to remember to slip the heat shrink on before bending, I always forget
Brilliant!
Clean, simple, cheap, low drag, low weight, quick to implement.....simply Brilliant.
Glad you like it!
Andrew, you are nothing short of a Genius! That's such a brilliant idea! Greetings from Los Angeles!
Not my original idea, but yes it works well
New to fixed wings, building my first plane, and wow, this is awesome!
Welcome, lots of fun ahead. You can also add a V bend in the middle to make them adjustable.
Man of many talents Andrew 👍🏻
Glorious! I haven't seen the "Springy Wire" bit before. Well done =)
Great use of low cost materials. Thanks as always.
Thanks for your tips Eric. Much appreciated.
Great video sir. Quick and easy way for push rods. I will be using these for sure.
Wow I like this technique. Definitely using it.
Go for it!
ust ordered assorted spring wire, great tip , gave up trying to find spacifics
Definitely using this on my DLG airlerons!
That's a cool technique! Should be useful for other things like carburetor linkages too. I might have to try that on my racing mower (always taking it apart to tweak something), and this would make dissemble/assembly go smooth. Thanks for posting this!
+Jake Garrett Racing mower! Those things are mad
brilliant simple and very effective method ....thank you for sharing!
Sure is, thanks
This is a GREAT idea!
It works but there is no adjustment, has to be the right length
I bet you could seek a small half loop bend in there close to the servo...
....either way, great idea!
Very clever indeed, I shall have to look through your channel for more information like this for beginners like me.
Many thanks and have fun,
Joe
Great idea! Going to give that a try on my next build.
Such a great way to make push rods and it looks much easier too. I can do this.
- Thanks
+SnapPunch Robert Yes you can
awesome idea. you want to make it even better? loop the smaller wire around the pushrod as to create an eyelet then make it so that it goes back inside the shrink tube so there is no sharp end. makes for a cleaner more robust retainer
Nice idea thanks
seems so simple but genius, well done sir, thank you for sharing
You are very welcome
Fantastic idea
Thank you! Cheers!
EXCELLENT JOB...ALL THE BEST
Bravo my friend! Great idea but I don’t think I would use this on one of my larger planes! Park flyers and maybe up to some 36 inch planes. Great tip however - thanks!
Great idea the clip, thank you
You've just saved me time to create push rod, forward Andrew. Your da man! Thanks! 😄👍
+Parkflyer Indonesia Excellent
I guess Im asking randomly but does anybody know a way to get back into an instagram account?
I was dumb forgot my password. I appreciate any assistance you can give me.
@Brixton Derek Instablaster :)
@Remington Ayden I really appreciate your reply. I got to the site through google and I'm waiting for the hacking stuff now.
I see it takes quite some time so I will get back to you later with my results.
@Remington Ayden It worked and I actually got access to my account again. I am so happy!
Thank you so much you saved my ass !
Nice.
Thanks Andrew
Smart idea - I will try it
That's awesome!
I like this springy thingy :thumb: Sometimes it may fit, sometimes I prefer adjustable pushrods.
+Tom Wolf Yup, good thinking
Brilliant. Thank you !
Thanks. Maybe add a little V bend for some adjustment too
So glad I happened upon your channel there Andrew.
Indeed a brilliant (as well as inexpensive) way to secure push rods between the servos and control horns providing both security, stiffness and strength with only slight increases in weight.
Cannot wait to try this but first I'll look for those pliers over at Hobby*King.
Welcome good Sir Knight. You do have to be accurate with your bends
Easy and Brilliant, thanks for sharing !
+Multirotor Go Thanks
Thanks so much. Great idea.
I do like this style of pushrod end and if the rod is long enough, you can add a double "z" before the servo for adjustment.
Good thinking I must try that
Best of both worlds!
Many thanks!
this is what i'm talking about, thank for reply with this video Andrew, helpful technique
+Druide Excellent, glad it helps.
Simple genius!
Been doing that for years. But I bind and solder, not cyano.
great idea
+sayid mohamed Again not my original idea, but it is a good one
Bloody genius. Thank you.
No worries
Bloody hell that's good. Thanks matey!
+Master Kammelryder No worries
Wow that is excellent...thanks for the great tip
muy bueno, gracias
Very nice. I have been looking for methods of making push rods vs buying 2 for $7-$10
Only downside is they are not adjustable, but they are cheap and unbreakable.
They make keeper ends that do this also!!
That's very clever!
Great when you can't find any connectors
Awesome!!!
Great, as always!
I was wondering when you were going to trim that wire off at the end haha!
Not into planes but thanks for this video.
If you can get the control horn off the servo then you could use z bends on both ends of the push rod?
Definitely, you can put a V bend in the middle of the pushrod also to allow some length adjustment.
Nice one!
I like the idea a lot, but there is quite a lot of play in the connection, which may make the aileron or ruder or what have you very floppy in the air. any idea on how to get rid off that?
Just have to drill the holes more accurately and use a drop of CA if the servo arm hole is to big.
I've found that the amount of "slop" in the controls really don't matter on most aircraft. Yank and bank foamies wont care at all. Sailplanes or high end stuff will need more care. Andrew is correct, check your drill and worst case, expand the diameter using CA. I use a caliper to check the diameter of the rod. Then select the proper drill bit when expanding or making holes.
The easy way is to heat the end of a pushrod up with a lighter and use that (without burning yourself) to expand the hole. Perfect size every time. Not my idea, was shown this decades ago by a man whose name i've unfortunately long forgotten.
love it!!
Really cool technique! But you gotta proof its bullet proof!
Haven't seen single bullet since I fitted them. Proof enough? Actually that's not true. I found a live shotgun cartridge on the road near the flying field.once.
Andrew:
Very interesting! I've never seen this before. I like the spring retention of the pushrood onto the control arm.
Is there a strategy to achieve the ideal pushrood length? I missed this point in the video.
If we get it too long or too short, must we start all over?
Jim
V bend in the middle allows some adjustment
do i use the smallest diameter shrink wrap i can find to attach the pushrod to its respective connection at the tail side?
Yes, 2 or 3mm
sweet, please make adjustable one also... would be great...
+Harindra W Pradhana This was to get away from adjustable push rods. Keeping it simple.
So the springy wire prevents the piano wire to go out?
+ABMNS PRODUCTION Correct, but you can still remove the push rod
wow!!! amazing.
Thanks so much!!! good idea!!!!
i like this electric dlg for its lightweight size. can you do an fpv build on it?
For FPV I would just pop something like this on bit.ly/2VBUgz1
Really nice mod! Thank you =)
genius!
Do you have adjustable Pushrod diy ? Video link ?
Just have to include a V bend to make it adjustable.
Andrew, which brand and model are those servos ?
No idea, just the servos prefitted
cool
Andrew, but what is the name of this tool for bending wire?
Z-bend pliers, it's in the video description
Is your missus building a new shed in the background?
+ChuckPlains Haha, sounds like it. Actually neighbours house extension
What's your local hobby shop mate? I looked on hobby king and they don't sell it.
+blairo15 Tates RC World www.rcworld.com.au
Hmm this is very special! Great sharing. Also, can you shoot bullet to it and still survive? hahaha :p
+Edward Chew A small bullet maybe :-)
Can't make adjustments without creating and entirely new push rod. I'm sticking with threaded wire and clevises.
Yes you can make adjustments if you put a V bend in the middle of the pushrod. You squeeze the V to make it shorter or you open it up to make it longer.
did you come up with this technique?
No, cant remember where but I saw in in a build manual somewhere.
Andrew Newton it's an awesome method
Unfortunately it is not adjustable for trimming aircraft.
Put a small V in the rod somewhere, so you can bend that to be wider or more narrow, like this ______Λ______
Good day where can I buy that tool
Hello David, Hobby King
Andrew Newton name of these tools?
Watch the video and read the notes
ok thank
I thought it was flite test video
Excellent
Fucking bangood they shipped me the plane without pushrods
Boo
Andrew Newton btw i made some myself
Brilliant!
Brilliant!
