[NSRCA-discussion] Connector weights was RE: Connectors - Electric

Tue Oct 16 15:47:21 AKDT 2007

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 :-). 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.)
