Why does every Lipo have to have a diff connector. I suck at soldering and is very aggrivating!! I'll spen a hour on just on Eflight EC3!!

Ec3s are about the easiest connector to solder. Shouldn't take more than a few minutes. Youtube has some videos showing how to solder them.

maybe my solder iron doesnt get hot enugh cause its not as easy as the videos. I cant tin the wire or connector. seems like it does not get hot very fast. Its a cheap radio shack iron.

In that case, you're done before you start. I use a Weller 100/140 watt soldering gun. Lots of heat for even the thickest gauge wires. The smaller (<50W) soldering pencils used for electronics will not work. I also use EC3's and they are quick to install with the right tools.

I used one like this for years and had lots of trouble. Was always taught not to oveheat stuff and use a low wattage device. Then I learned that high wattage was better because you can heat and get out quick. I bought this and my soldering has been transformed. I look forward to soldering now.

Even with shipping this is dirt cheap for this station which is a clone of a t$100 soldering station.

Part of it is probably the iron. Part of it is usually the tip. You not only need the wattage to heat the tip, you need a tip big enough to hold all the heat you're about to transfer. Youtube, and don't look at any of the surface mount vids, they will steer you in the OPPOSITE direction.

Edit: And flux, google "kester flux pen". See if you can find a #186. Will really help with getting the solder to "wet out".

You must keep the tip clean for good heat transfer. Use a damp sponge between tinnings to keep it shiny. Also, make sure your solder is 60/40 (tin/lead) to promote easy flowing. Practice on some scrap wire until it becomes second nature. It is an indispensable skill for electric fliers.

Last year I found a video that made a huge difference in the ease of doing EC3 and EC5 connectors. I can't find it now but here is the idea. Don't hold the iron by hand. Tape it vertically to a block of wood with the hot end up. File the tip so you can put an EC connector on the tip with the solder pot facing up. let it sit there until its good and hot. Then put a little solder into the cup. Then insert the already tinned wire end. Make sure it remelts the tinned wire end and everything is molten. Then use pliers to lift the connector off the iron. Hold it still until the solder hardens. Then while its still warm press it into the plastic part with a 1.5mm hex driver.

You do need a decent size iron. 45 watts seems to be enough for even EC5's and should be plenty of EC3 but more would be better. I have never liked guns that much.

I found the video. This is the best way to solder EC type connectors.

You do not need a 50W iron to solder these connectors. I use a Weller WLC-100 soldering station with a 40W iron and it's plenty for the EC3, EC5, Deans, whatever. I also have a Weller 200/260W gun but I rarely need it for soldering connectors unless I'm soldering 10 gauge wire. As mentioned you need a large tip but you definitely do not need more than about a 40W iron.

I bought the weller 40watt pen type from home depot a few years ago and i has served me well for these connectors. The biggest thing is you need to keep the tip tinned and very clean. Once you let it get all gunked up with crap it's not going to transfer heat well.

One thing to avoid with EC3 is allowing any solder to run down the outside as there is a small groove that locates it into the insulator
If you paint some white typing correction fluid ( Tibbex ) on the outside the solder will not stick and is easy to remove
Be careful putting the insert into the insulator as if you are holding it with your fingers the screwdriver can slip and go into your finger
Yes I did it but only once
Just a bit of practise will see right
Cheers Jim

Ditto.

I have a 40w iron and solder 10ga wire to 6mm bullets. I all happens very quick & easy with plenty of heat.

Usually the problem is the use of metal alligator clips or pliers. They'll suck up all the heat, which will require a higher wattage iron.
Holders made out of wood are the ticket. Wood blocks, clothes pins, etc.

if you hate soldering check out Power Poles they crimp on youll need to get a crimping tool for them but its so much easier

I was just about to say the same thing. APPs with a crimp tool allows you to install connectors in seconds.
