Connectors or Direct solder for esc & motor?
 

Do you guys use connectors to connect your motor to your esc or do you solder them directly?

If you use connectors which are preferrable? Power poles?

I've only had experience with Novak BL so I haven't had to make the connection between the motor and esc.

Thanks in advance, this site rocks.

well most of use just use bullet connectors simple because of ease and because of the low resistance. i.e. less power lost and you wont melt the connectors together like the tamiya ones do.

Corally female plug's work best. Solder the wire as deep as possible and fill the gap in the middle with solder. Don't forget to put on some heatshrink first.

For the Feigao motors, I solder direct to the motor wires usually. The connectors are convenient if you plan to change motors, but a direct solder connection is more reliable with lower resistance.

@mike;

that depends.

If you solder a wire directly to a wire, sideways, the contact area is very small, and there for a rather high resistance. with tight fit plugs, (tight as in, wire to the plug)
there is allmost no solder between the copper and the plug.

@ Serum

I don't think your right (I probably don't understand but intrested in why) If I was to connect deans on, I would still be soldering the wires to the dean on one side, so it would be the same but also resistance from the connectors bonding too.

Unless you mean something that wraps around the whole wire like bullet connecters?

yeah, i mean those bullet connectors. surrounding is the best way to keep resistance low. the deans are rated at 60A, not for nothing.

It sounds like you are suggesting these Bullet connectors. Are these3.5mm gold plugs the best connection?

If you really want to put some serious current through your plugs check these:

Mike could probably get you some of these with his next BK order.

Not too useful for 1/18 setups though...

Yeah, i ordered those connectors from BK as well Felix. i thought about 16 sets in totall.

@ Papa, 3,5 is rather small, i would got for a minimum of 4mm.

How many do you get for $2.61?

1 set

Since the solder itself is the least conductive material in the chain, the less solder the better.
You need only one point of solder if you solder the wires to each other, but you need two points of solder to add the bullet connectors (one for the male and one for the female).

Personally, I plan to always use connectors because I move the setups between vehicles regularly and need to make sure I can plug one controller into different motors, etc...

Would powerpole connectors offer a quality solderless connection?

Amen Batfish.. soldering a wire to a wire is not the best connection imo.

powerpoles are good connectors, i know them from APC UPS, the big 350A types. I was impressed by them, it was love at first sight. The contact pressure is topnotch., you need a lot of force to get them loose. i don't understand why they are not used for RC. perhaps it's the soft wire that makes them less suited for the cables as used in RC. the 175A is the best imo. perhaps it's their size that keeps people from using them.
