How to Solder Bullet Connectors to Brushless Motors and ESC

[brushlessmicrot]

im about to do this on my brushless micro t i hope it works

[bcdvideo]

Thanks for the tip! :)

[sam1741]

Thanks! simple and helpful

And wonderful idea on the wood

[chubbychicken1234567]

Could you solder female deans to align esc for a trex 250

[xoxbamfan]

Hello, would ut be possible to solder the esc to the receiver bc my esc wire is small and Wong fit....thanks

[mmmartin261]

so do you have a video for .8mm bullet pins soldering? I want to replace the stock pin connectors on my gaui330x with something more crash worthy.

[mmmartin261]

its called editing and maybe try a script to dispose of the points that annoy us.

[Gottisanidiot]

Nice vid. I assume your wires are 12 gauge. What size are the connectors?

[lmuchacho7]

Brilliant idea for the wood board, it will also warn you naturally if you eat up the connector for too long.

At minute 3:55 to 4:00 in the video you solder the yellow wire. If I may I think you should heat up a little bit longer. By applying solder in the bullet and warming it up you are "Tinning" the metal of the connector we can see the same as been made to the wire when you put the wire in the bullet connector you have to make sure both area do melt and create a solid bond

[Soaronex]

Thanks 4 sharing the idea!

[LTF85199]

Great tip thank you!

[AlaskanGuitarz]

Thanks very much for showing how to do this!

[paragpandit]

Why 6 holes? Destroyed a nice piece of wood :( Everyone shouldn't make build videos. Too expensive equipment. Its skill and worth a video if you show it with a lighter. The topic is off too. It should be putting deans or whatever connectors on a whire. You fooled me into watching this shit because I was searching for the right way to connect a brushless motor to an ESC. Polaritywise.

[731thing]

@paragpandit ur an idiot just match the colours or if that doesnt work go off the writing.... btw greyson hobby its a good video

[paragpandit]

@731thing No. My motor has 3 black terminals and ESC has 3 terminals with A, B, C on them. Piece of wood, drill, heat gun are not the tools required for soldering :) I still think its a ridiculous video. Sorry.

[voltoman]

I just soldered my esc and motors like shown in the video, but made sure to hold the cable really still as the solder cooled, and I used really high quality solder. Make sure the solder is shiny after it cools, and if it's not, melt it again and hold the wire still this time.

[fireworkstube]

How about one for the battery connector that comes in the combo's? Actually, how about a video that shows all of the soldering steps and wiring for one of the combo's? Love the combo's but the lack of instructions is a bit of a head scratcher!

[gfxartist]

Very poor "how-to". Moving the connection while the solder is cooling?! A fundamental skill in soldering is to NOT disturb the solder as it cools. Moving the cooling solder can cause "dry" joints that can crack and may not conduct as well as a proper joint. And as others have mentioned, clean the tip.

[optimistONE]

This is very helpful as I am starting my first attempt at soldering this week. The wood seems like a great idea. Thanks for the clearcut informative vid.

[heberorozco]

where can i find the swring wrap?

[heberorozco]

graysonhobby is the best of RC !!!

[olliegamer]

what connectors did you use in this vid

[Artelian1]

Hi,

I just buy a brushless and speed controler.

But haw can i know wich wire go were ?

I never do this.

If I do wrong I can burn the engine ? Tank You.,

[voltoman]

@Artelian1 On the 3 wires going to the motor, it does not matter which goes where. If the motor spins the wrong way you can just reverse any two of the connectors. No damage will result. However you want to make sure you have the polarity correct going from battery to the ESC, or it may result in damage. (those are marked red and black tho, so you would really have to have your head on backwards to get it wrong.)

[davokidd]

veryy helpfull. just bought a brushless motor and need to put these on. cheers

[mdore71]

thanks very new just typed in how to solder bullet connectors found video  thank helped alot

[azayles]

That solder iron is in dire need of cleaning and whetting lol. Use a brass sponge and rub the tip over the sponge when the iron's hot, then apply solder. Gives a much better cleaned and whetted tip than a wet sponge.

[nitroductionx]

perfect video. thanx

[Sixtyninecents]

Great vid, just got back into the hobby and have bought two rcpowers kits from you guys which are just awesome. If you have any tips or tricks for soldering the deans connectors that would be awesome. I keep getting the deans connector too hot and melts a little bit. keep up the great work, and thanks for helping.

[hiddenasskiker]

hi im wondering does it matter when you plug it in with the speedcontroler and the motor does it matter how you plug them in like 1 2 3 or just randomly?

[gjferg]

Hi. Don't know if you found your answer or not, but you can plug in the wires in any order. If the motor is not turning the right direction, reverse ANY two wires to reverse the direction of the motor. The motor doesn't care what order the wires are connected nor does it care which direction its turning.

[hiddenasskiker]

ok tnx mate im new to all this usualy i drive rc cars but been flying for a year but mostly i got RTF planes and helis so im going the next step ARF planes but tnx again mate

[greysky1974]

1 57 thats a super quiet drill awesome

[pudd750]

why do my cups have holes drilled in the sides of them? the solder doesnt leak out when wet , but it seems funny theyd spent the time to drill each one -- ive been told "dont move the wire as the joints cooling- the elecrons wont go thru as good" as if the joint wasnt moved wile it was cooling - does a hair dryer get hot enough for shrink tubes?

[pipercub37]

Holes in cup are for crimping the connectors if you decide not to solder them. It's best to solder the connector though.

[pudd750]

wow - thanks, true ,ill keep soldering too - i load my bullet in a helping hand clamped in my hobby vise -

[MrFoxy101]

@pudd750..

Turn the kettle on and put the heatshrink over the steam, it will work just fine.

[dusmava]

Great!!!!!!!!tks.

[pinzgauernorcal]

i wish i saw this video before i did mine

[th4002]

Your way of welding is not very conventional!! You put welding inside then the wire, they are not good. (nonoptimal sodure and not to the standards)

It is necessary to galvanize the two parts, puts the wire inside connection, to apply iron and to put tin, and to make so that tin is not maintained in heating too a long time.

greetings

[pudd750]

he forgot to mention the wires are almost always pretinned

[MrFoxy101]

@ th4002.

Perhaps it's not conventional because this is soldering, and not welding. *LOOK AT THE TITLE*

[blastergti]

Nice trick with the piece of wood! I'll use this trick next time I'll solder, it'll definately make the process easier and the result better. Now I don't have anything to remark except that the wires should be applied with solder Before putting them down into the "cup" The wires might cool the solder in the cup so that the lead doesn't adhere properly to the copper. This will cause power losses. This also happens while moving the lead during cooldown. (I'm into electronics engineering)

[moh199702]

what are bullet connectors

i am new to soldering

[achilles22382]

thanks tons, very very helpful.

[cj2006sd]

Great video!!! Awesome technique!! The Grayson 30A ESC has all black wires....what is what? Which one goes to what color motor wire. (2212-06 V2 Supersonic)?

[angrygunsmith]

from where the wire starts in th esc it shows the polarity on it.

[mannnick]

plug all esc wires to motor (2 for brushed or 3 for brushless) if motor runs backward then swap any 2 wires over - thats it

[Sonicman1979]

Very informative info for my electric plane conversion. Thanks for posting!

[kiteboarder6]

wow this vid helped me out alot, thank you

[neavissa]

great video. thanks. do you use those on batteries though?! if so, how do you prevent them from shorting out?

[graysonhobby]

No do not use those on batteries..Use Deans aka T-Plugs, JST, or Micro Deans

[neavissa]

ok, thanks...i am using EC5's now. from losi.

[fattychan1234]

@graysonhobby yes u can use bullet connectors for battery's you use shrink warp to stop it shorting out.

[Grimgorus]

Heat gun? You mean hair dryer?

[joehandsome99]

Actually, that was a heat gun in the video and not a hair dryer. The heat gun works well for the type of work he was doing in the video.

[timbulb]

Hair dryers don't get hot enough.

[tallguysd]

great video it's videos like this that let people understand how this stuff works.

[MTEXX2]

Great idea. I made this jig, too, and it makes soldering a SNAP! I went from about 10 minutes per set of 3 to maybe 2 minutes.

I spaced my holes about 1/2" apart, which I think was an improvement. Also built a Dean's hole which likewise speeds that process up about 3X.

Cheers!

[wally53511]

Please wear safety glasses, especially when filling a cup with solder. The flux can get trapped at the bottom, and spurt hot solder straight up. Some varieties of solder also sputter flux, which can get into your eyes. Lastly, please don't dip the wire into acid core flux. Your connection will fail if you do.

[ALTN8NRG]

@wally53511 Thanks for the good tip!

[xlovegroovex]

Just thought I'd mention that if you touch a bit of solder on the tip of the soldering iron before you put it on the connector it will help to conduct the heat better. Also, it's important to try and keep the cable as still as possible until the solder has solidified, otherwise you will get a dry joint. For those of you that don't know, a dry joint will be dull and greyish. A good solder joint will be shiny and silver.

[paulkazjack]

just about to say that!you beat me

[MTEXX2]

Thanks, I didn't realize that.

Now, off to re solder about 20 connections : P

[ClodAholic]

very helpful i was worried this was hard, you made it look easy thanks for the tip!

[Sqito1]

Does it have to be 40W?? I see you are melting the solder through the gold connector. Does a 15W soldering iron have enough power to conduct the right amount of heat through the gold connector or do I have to do it from the inside?

[farmfanugan]

i tried a 15w and it did not work too well.

a 40w makes it a TON much easier.

[MTEXX2]

Get the hottest you can. Soldering wiring like this takes more heat than a circuit board style iron.

[crazy9catears]

very helpfull

[kyong9]

if you fill up the female connector with solder, how will the male fit in then?

[Balthazar70]

You fill up the end with solder where the wire goes, not the end where the male fits in.

[FuknNuts]

This method works great! Thanks for putting this on here. Otherwise my ESC would be in pieces after I got mad enough at the previous attempts to get the bullet connectors to stick to the wires.

[UnsulliedSpy]

A good tip for getting the holes drilled to the right depth is to put some masking tape on the drill bit at the desired height, that way you don't drill too deep or too shallow (just stop when the tape gets to where you're drilling).

[bhelpurii]

You should put solder on the object being soldered not the soldering iron

[wally53511]

Because the flux reduces tip life

[bhelpurii]

No, because the rosin flux should melt onto the object not the soldering tip

[wally53511]

Correct. Rosin is an acid at high temperatures, and will erode the tip eventually. Having said that, I admit guilt to doing it to speed up the process.

[toober360]

thanks!! who sells those bullet connectors?

[n0m1c]

Great tutorial. Thanks for the tips!

[swoosh343]

Excellent tips on soldering...educational.

[bm5447]

i dont give a shit how old ur solder iron is!

[MaverickGrabber71]

@bm5447 There's no reason to talk like that.

[sharingan180185]

Does the solder should be with flux?

[graysonhobby]

It helps, you can buy Flux at any home center in the plumbing dept. A small container cost a few bucks and can really be usefully in other soldering projects

[staver76]

@graysonhobby If I wanted to solder a 48v ebike 1000w hub motor to a 48v 20ah battery can I use these connectors soldered on the copper wire of the hub motor and battery?

[sharingan180185]

very informativ thx but how much did you fill the connectors?

[graysonhobby]

Almost to the top. You really cant add too much, if you do, it just poors out the sides

[pojiegsr]

great! thx man

[fathead431]

this has really helped me!! great vid!!

[RCSuperPowers]

I dropped my soldiering gun on my head one time...

[RHEAD100]

Thanks; Very informative. And well done.

[wmacorlando]

Good Stuff!

[zlurunul]

very helpful!!

[vgarambone]

Very well explained. You helped me a lot. Thank you.

[redhatman]

Thanks a lot. I have been to Graysonhobbycom before and it is an excellent website. Keep it up man, great tutorial, great site. :thumbsup:

[SuicideNeil]

Excellent tutorial, will come in handy for me & alot of other people too.
