OSE 5.5mm bullet conectors - Tips to solder motor wires??

[Racer944]

Hi Guys;

I bought a bunch of OSE 5.5mm bullet connectors to redo my motor and ESC connections. they look like high quality connectors but I am perplexed why they have such big holes on both sides of the connector.

Does anyone have any tips on how best to solder these?

It seems pretty straight forward for large guage wires as they would fill the bullet pretty well, and the solder would stay somewhat contained, but how are you guys soldering these onto your smaller guage motor wires? With the holes in the sides you can't pool the solder into the bottom and insert the wire, so are you soldering the wires to the (in)sides of the connector somehow?

Any tips or tricks appreciated...

Cheers;

I drill a hold in a piece of wood and place the bullet in it so it's sticking straight up. I tin the wire. Then I heat up the bullet and fill the area where the wire goes with solder (not too much). Then I grab the wire or motor and heat the bullet again till the solder melts. I place the wire in the bullet and hold the heat on it for a five count. Then I pull the soldering iron away and try to hold the wire steady untill the solder solidifies. Blowing on it helps. If I'm using a brand new bullet, at the most I'll have little solder bulging out the sides of the hole. I'll give that area a quick wipe with the iron to take it off.

Maybe not the best way but it works for me.

Exactly how I do it as well.

Ok to clarify, are you guys saying that the wood "holder" is drilled deep enough to block the side holes in the connector and therefore the solder from running out?

Nope, Just deep enough to hold the bullet steady. Fill the cup up 3/4 up with solder and when you attach the wire it shouldnt run out the side holes. Maybe just bulge out a little.

No one said anything about the tip or type of soldering gun/iron they are using. I do the same as above but i use a small gas soldering pen with a mini blowtorch connection to heat up the connector then melt the solder inside.

I dont use lead free solder, Horrible stuff as far as im concerned. I only use 60/40 lead solder.

Blowing on it helps.

This comment got me laughing. It's a great tip. I suggested that last night as well. But to my wife....

But to the point, I found it helpfull to coil the wire into the cavity as well, adds way more surface contact area and keeps the wire more stable durrign the process.

I solder 8 Gage wire and bullets using 60/40 solder. I found it much easier to use a mini torch (Harbor Freight) to heat up & tin the wire & bullet separetly. I use a "helping hands" (Harbor Freight) tool to hold the bullet at a 45 degree angle with the side hole facing up. Once the bullet is hot enough to melt the solder I back off with the torch, reheat as needed. If you are careful you can coat the bullet with out solder running out of the side hole. Once the bullet is tinned place the pre-tined wire against the bullet (hole side up) heat both up untill the solder melts & push in the wire. I've been using a damp (not dripping) kitchen sponge - scotch brite side to wipe off any spooge & cool down the solder with a corner of the sponge side. Beats the crap out of frying your fingers on a hot wire & blowing to cool it off. I've used this method on 10-12 Gage wires also. It's faster & easier for me than using a soldering iron. JIM

I use a 140W solder gun for the big wires. A standard 40-80W iron with a large tip will work, just takes longer. If solder is dripping out of the connector holes then that's too much solder-- practice on a couple of connectors and spare wires to get the hang of it
