I agree -especially if you are careful while making the connection. More solder doesn't make a better connection, just like if 2 Tylenol is good then 4 will really help- NO and it may make things worse.
I purposefully only weighed new unused connectors just for the reason of the variation of solder.
The only thing I have both used and unused in is Schultze 4mm. I will weight them seperately and see what I get and report back.
Now that I've made up a few connections I feel as though I'm not overly applying the solder anymore. It had been about 20 years since I did much soldering and it took a little practice. Besides growing up in my dad's TV shop he didn't care how much the solder joint weighed as long as it was a good connection<G>.
I only did the weights for comparison out of curosity and because I have a pharmaceutical grade balance at work.

I've read where you guys weigh the connectors, but do any of you weigh the solder that you use as well? Seems to me there could be a difference with some connectors.

Eddie,
How do you hold the female connector when soldering the wire? It looks to be a little thin wall.
I just got 60 pairs of the 6mm from DraganFly. I will probably use them on my next project. Amazingly light compared to 5.5mm that I used on the other setup.

OK the weights of the different connectors kept weighing on my mind <G> SOO I did some weighing.
Unfortunately I only had a few pairs of each size NIB and we all know there will be variations in units depending on QC. But here¡¯s what I got.
I weighed 2 pairs of each but then realized Deans 1pair(1 male&1 female) handles 4 wires, 2 on each side.
The bullet connectors take a plug for each wire so I weighed 2 pairs (2male&2female) each, because that¡¯s what will handle 4 wires, 2 on each side.
Deans 2pair 9.302Gm/2pair or 4.651Gm/2 for an average of 2.326/plug
Schultze 4mm bullets 6.746Gm/2 for an average of 3.373/plug
Neu 5.5mm bullets 11.326Gm/2 for an average of 5.663/plug
Neu 6mm bullets 6.647Gm/2 for an average of 3.324/plug
Of the choices of bullets I had available the 6mm Neu are the lightest and handle the largest wire. Current & amperage is pretty close if not the same on the 4mm, 5.5mm, and 6mm choices .
Now putting a 3.5mm(11Ga) wire into a 3.5mm connector sounds almost like magic to me J. I would love to see weights on the MPJet choices but I didn¡¯t find any listed on the site. If anyone has them send me 2 pair & I¡¯ll weigh them and send them back.
At first glance, and I made the same mistake earlier, Deans appeared to be heavier than the Schultze 4mm & the Neu 6mm. But I was weighing 2 pairs of everything.
In my setup I have 6 Neu 6mm bullets (3 pair) for a weight of 19.941Gm + 1 deans pair ,arming switch, that I plug 1 male deans into to fly so add another 4.651Gm for a grand total of plug weights 24.595Gm
In the Dean setups I¡¯ve seen usually there are 5 Deans plugs counting 1 for an arming switch for a total weight of 11.628Gm
Although Bullets are heavier and you need to keep the males insulated, they are SO much easier to make up that I¡¯m happy with them.

Right - no problem removing the plating where the wire will be soldered (Use a good solder with a little silver in it - I like Deans racing solder). The gold plating prevents oxidation (which is resistive) on the connecting surfaces.

These 3.5mm plugs are gold plated, my wire wont fit the socket. But I hate to drill them open since they are plated, but the base is copper I assume so does it make any difference as they are getting soldered anyway?

The Hacker Comp plugs (female for ESC to match those provided on motor) are 3.5mm. Jeti 3.5mm from Esprit work. If you don't mind changing the motor side, others will work too. Drilling the wire side deeper and cutting off the excess can save weight.

Anyone know what connectors are used on the Hacker C-50 set-ups? They look like the 4mm plugs on the Neu site, just wondering if anyone knew for sure.

These might work for you as well.

Brian, those are really sweet connectors. Let me know if you find a supply.

Im trying to find MP Jet 3.5mm that accept 3.5mm wire (11ga) to fit my batteries. Anyone have any source on these in the US?
http://www.mpjet.com/news/index.php?option=com_wrapper&Itemid=28
Deans are an option I guess but would prefer the bullets.
(As a side note I have some 3.5mm MP Jets that accept 2.5 mm (14Ga) wire if anyone wants some.)
