Connectors or Direct solder for esc & motor?

[Papa]

I had the 75 amp powerpoles in mind. The SB series is just Huge!:eek: I have seen the deans vs powerpoles debate before.
Matter of preference I suppose.

@ Batfish For a motor /esc connector are you saying gold plugs?:C:

[Serum]

Yes Papa, he does..

[Batfish]

Yes, I use the gold bullet connectors for the motor/esc connection. One of the main reasons is that so many of the motors and controllers already have that type of connector already. For example, the Lehner xl4200 I bought here had 3.5mm bullet connectors on it already, so I just had to add 3.5mm bullet connectors to my MGM. The new-style MGM controllers have 3.5mm female connectors on the controller itself, so you need to put 3.5mm connectors on the end of the wires you plug in.
For me, it's a matter of convenience and reliability.

I suck at soldering, so I try to solder as little as possible :)

I love the standard 35 amp PowerPoles, by the way. They are the only connector I use now on batteries. I've been thinking about using the 45 amp inserts, but haven't tried them yet.

Mike has the 5.5mm BK connectors,at least he did have them in stock when i ordered last.My 20xl came with them,good for the 9920 double wires too.

20XL?! :eek:

[Gustav]

Yeah a 7xl,is a BK 20 series XL 7 turn.should have said 20XL/7 maybe.

Just said 20xl 'cause i don't know if the Fiegao xl comes with them.

I use those fat BK plugs too. They feel like business. I think they are good, I will put them on my setups if I intend to try different motors on that ESC.
I use those 3mm bullets too, sometimes.

You CAN make a wire to wire connection quite effective, actually. I you take a non-pre-tinned 12g wire (ESC), remove 5mm from the insulation, and push the motor lead into the fine strands, so the strands are all around the motor lead, and then tin it all up, I guess its not too bad, either.

The main reason I prefer direct soldering is reliability. I have had on more than one occasion, the motor come unplugged during a race, or partially unplugged(this happens all the time). With a direct solder, this can't happen, so it is one less thing to worry about.

[Nick]

Bullet connectors you use pliars to fix them onto the wires? I guess it is best to add abit of solder too?

[Serum]

if you are worried about the loosing contacts, because plugs get unplugged, you could use a piece of heatshrink that coveres the entire plug, they won't get loose that way.

I use 4mm gold plugs and you need quite some force to plug them in or out.
I have a hard time imagining these unplugging themselves due to some vibrations...

Mybe if the controller isn't fixed to the chassis?

I was gonna use deans connectors when i get my brushless, i guess i'll look into some other better connectors now.

Mike knows how to mount a controller Felix... (I guess ;) )

[RC-Monster Mike]

Pretty sure I have the controller mounting thing down. :) The problem is the sometime very large jumps at my local track, along with an occasional driver error. A sudden impact in the right direction can pull the plugs out. I use 3.5mm plugs, not 4mm, but same idea. Another thing I have against the plugs is the wear. They loose their spring tension over time, which eventually leads to what I described. I use plugs on some, direct solder on others. I prefer direct solder.

I like the 3.5 mm plugs. I have to agree with mike on the coming out. I have done this while bashing. It would really effect the racing. A soldiered joint will have less resistance than a unpluged resistance. I still like the connectors for the simple fact of motor or esc swapping.
