- I have had a few messages on the channel on more detail about how to crimp. This video is a result of subscriber questions.
Here I show what you need, how to do it and cover the costs of the tools you need to do the job.
Thanks for watching, please LIKE, SUBSCRIBE and Happy Flying!
Everytime I need help, google bring me to your channel! God bless you Painless
Just bought a pair of Hobbyking jst sh crimpers at a great price, real handy bit of kit for all your crimping needs
£10.28 shipped from uk store arrived in two days and great quality auto crimper, very pleased with them.
As always a great vid well explained and very useful, cheers painless 👍🏼
simple video... Amazing info..... thanks
thanks. these instructions was very clear and helpful.
Thank you very much for this video!
Great video. Thank you very much!
Very, very clear and well explained. Brilliant, thanks very much.
Thank your you for the feedback. Happy flying!
Nice work. Very helpful video.
Awesome info! 🙌 I have 2 servos that need and put on them.
Great instructional video!🙂
ooo i just bought those!!! I love them. Just having a hard time with these small pieces. My vtx cables are always ripping out . So decided its time to make my own wire harnesses.
+VEL SKI strip twice the wire length and turn it back on itself to get more material in the crimp. Crimp the conductor and insulation parts of the crimp separately. Best of luck!
Awesome, thank you very much for the video :-)
Great info
very good vids Thanks.......................
I have been crimping wrong. Thanks very much.
+Famous Internet Guy Not necessarily! I use this method (spate crimp for the connector) as I've had experiences in the past where there has not been enough conductor to be well caught in the crimp but the crimp on the insulator on the cable has made it look and 'feel' like it's a good connection. Only takes a crash from that once for you to triple check ;) Happy crimping!
Gracias artista !!
Love the hi-tech graphics!! Dont blow your production budget in one video...hehheh. Thanks for sharing.
I was SOOO close to getting airborne, especially with your help....and then....i wouldve put my Screwup at the absolute bottom of the list. Nowhere in my thoughts did I consider that I might overtighten the prop spinner to the point of snapping it off...aluminum and massive forearms dont mix well.
Dont feel bad I used locktight and ruined two brushless motors on a Catalina ep
PyR0Star A model Catalina PBY? Wow.
John Robertson Dynam =)
Found a nice servo wiring kit on Amazon for about $15, male/female/JR wire/connectors. (Used about half of the connectors the first time I converted battery connectors. lol)
Love your videos, and I think I'm going to start crimping my wire and insulation separately now to check for good contact on the wire. Quick question, do you know of a good pin removal tool? I have no problem lifting the tab up with a jewelers but I'd prefer something pin specific that I could shadowbox in the tool drawer. I read on a thread that you can insert something in the wire side and that will disengage the locks as well so maybe I'll just make something.
+playeuchremore I've not come across something. Let me know what you figure out..
I've had success sticking lockwire down in the wire side so it's doable. I'm going to get some metal insertion/extraction tools for D-sub crimp pins and see how they work. I may have to box the ends with a needlenose, but it should do the job just how I want. Toss a few in the benchstock and no more digging for the tab with the jewelers.
fine!
Magic. How good is to have some guidance?
How deep does the wire need go into the pin? Must the wire completely occupy the opening of the pin; the part that goes into the receiver?Thanks!!
You need to make sure that the space under the crimps is taken up with the conductor. Best of luck!
Does the orientation of the pins have to be identical for all leads? Thanks!!
They all go into the servo connecter the same way round, usually the wires will allow you some movement but I try and crimp them all the same way for ease of assembly. Happy flying!
I looked for this tool and connectors several times but I never found it. Could you find a link on ebay or similar so that I can dig into the specs.
Thank you. And thank you for your great videos.
+Thomas Lund Thuen Search for 'Dupont' connector ;)
+Painless360 Found it. Thank you :)
Do I need to have a servo crimping tool or can I use a regular cheap crimped?
I've only used the proper tool... Best of luck
Brilliant as always Painless360! Thank you.
Would it be possible to post a link or a specific name to where one can buy a crimper kit like you have? Cheers . Marc (crimper virgin)
I've had mine for so long I can't remember where I got them from... Happy flying
@@Painless360 Ok thanks. Do you know what size pins I would need for servo sockets? I am looking for a kit similar to yours but I am not sure on sizing/what to look for. Excuse my ignorance and thanks for your help.

How thick is your crimptool?
I have one similar to yours that is 6.6 mm thick and I find that it often bends or crushes the connector.
+jeroen79 I'm not sure what measurements you're talking about..
I mean the metal plate that the tool is made of.
Mine is from 3.3 mm thick plate.
So the outer jaw, which has 2 parts bolted together, is 6.6 mm thick.
Because of Sod's Law I solder the wire to the connector as well as crimping, for the smaller gauge wires to give best retention.and when ever possible I always use silicone insulated wire.. not possible with the mini APM as it has impossibly small connectors on the APM/GPS MAG side that I cannot reproduce.
Smaller wires soldered run the risk of breakage due to the increased stiffness, where once they were flexible, and the crimper cannot get the same pressure on the solid joint.
John Robertson
Don't let the solder wick up the wire, remember the strain is taken up by the last crimping clamps.
TheRogerx3 Oddly, as an electrician, soldering is a weak skill for me. I really want the solder to work, but it doesnt share my goal.
John Robertson Stick at it. Soldering isn't just about knowing how to solder it is more practice than knowledge. I have been soldering for years and after a while you just 'know' when you have a good solder joint or not. If you want to solder, you must practice, much like any skill. So keep at it.
However, crimping does have it's place, and this (servo plugs etc) is it. I always prefer a solder connection to any other type but there are pro and cons to both as some have been mentioned above. Crimping small signal cables is often the way to go as there is no solder to wick up the cable and cause a rigid connection. You cant get a dry or loose connection from crimping provided the crimp is sufficiently larger volume of pressure than the copper itself, whereas with soldering you can possibly get a disturbed or cold joint (cable moved before solder solidifies or where the solder did not completely melt to the desired temperature). There is over heating, over wetting, and other things that can happen if the solder joint isn't correctly done. With practice though you can make a good solder joint, but also tell when you have a bad solder joint (that can pretty much always be rectified easily by redoing). I digress however.
Crimping a cable is often easily seen to be good or bad. After crimping give it a tug and if the wire stays put it is more often than not a good crimp, provided the bare wire (copper) part is crimped and not just the other sheath of the wire. But there are other factors to weigh in such as the quality of the connector, it's plating material, the thickness of the connector metal etc. Basically this comes under the quality of the connector itself and should you use cheapo connectors (I mean very cheap, like the cheapest you find on ebay from China. Often a too good to be true price is, too good to be true). In my experience I have found some connectors to be quite bad (IMHO) quality and have excessive residue from manufacturing that would create a bad contact, plating that likes to flake off when the connector metal is bent (such as in crimping) and also fracturing in the metal when crimped. These are some of the reasons that you may find a big difference in prices from different suppliers. When ever I use a connector from a new supplier or a different connector from previous I (mostly ;-) ) check using a microscope (yes, the cheap type form ebay! I know, I know.... There is always a line in the sand for every different person. What works for one may not work for another) and look at the crimp/connection and check for signs of cracking, plating detaching or other signs of a poor crimp/connection.
I do apologise as I have gone off the track a little, but I hope this has been of interest and may help a little.
Simon Maxwell Holy crap man! I dont know which I need more time for...learning to solder, or reading your wall!! Hehheh...
Ive typed a lot in the past, but not 60 extra lines...LOL. Ok, open a beer, start reading. It must be important, or you wouldnt have taken all that time to prepare your addendum to the Gutenberg Bible.
ps...one trick I do when crimping small wires, is to insert them parallel to each other in the crimp barrel, either from the same end, or opposite. Then it becomes wire to wire, and less likely to not use up sufficient space. Ive been making mechanical connections since the early 80's, so Ive developed a few tricks.
:?]
what sze crimps do you use my crimps seem to be too short so it makes it hard to connect to pin hearders.
I use standard DuPont crimps that are used in the servo connectors..
Painless360 hi do you also have any idea what connector and crimps fpv cameras use.
Plz provide the link for the cheap one on banggood
Is there a tool and headers for the little micro plugs i.e for the F3 or the telemetry headers for the D4r-ii
+Brighton Till I Fly Yes there are but they can be tricky to get. I'm looking into finding a place that does the crimper tool as I can see the crimps on eBay..
Best of luck.
Thank you, but what are they called so I can search.
JST-SH I think..
+Brighton Till I Fly JST-XH or JST-SH.
playeuchremore You top Man!
can you do a video on a picoblade 1.25mm crimp??
I am planning on a updated crimping video. I've got some PA-09 crimping pliers for it too. Stay tuned! :D
th-cam.com/video/dL-BiQGv1xc/w-d-xo.html :D
is there a minimum length that servo wires have to be?
Not really, as long as you have enough to make the ends off easily you should be fine!
very important to used high quality materials and tools. use pro tools , don't go cheep! inspect with a magnifier!
where can get this crimp tool ?
+Pushparaj Ameen The usual places - eBay, Amazon, local hobby shop...
in the U.S. a "dry solder" is called a "cold solder". And is avoided with proper training. But of course , if the student , does not have the capacity to properly learn and apply the lessons learned then you have videos with people that say things like " i don't like" or " its just as good"
never confuse a crimp connection with a solder connection each have there place and is better for there designed application.
ugh! focus. The only part I really wanted to see was exactly how the connectors go in to the crimp tool because I keep mangling the ends....especially the last bit of crimping on to the insulator. And, that's dark and out of focus.
+bob holkan do you have similar crimps?
Painless360 yes..similar. But I can't tell exactly. I'm trying to see exactly how the connectors sit on the die. I think that's my issue.
+bob holkan if you open the jaws you'll see that one side has a slight larger opening for the cable crimp and the other side has a slightly smaller, tighter crimp for the conductor. The temptation is to put he whole crimp in and try and do both at the same time. Sometimes the crimp can catch the insulation and not make good contact with the conductor so I place the crimps for the conductor in first (using the wrong side of the tool) win the insulator crimp outside the jaws and crimp using two operations to guarantee a good electrical join. The side you are supposed to use usually has the writing. Hope this helps..
+Painless360 Thanks! that's a great help.
