Default Best bullet connectors for motors?

What do you guys recommend for bullet connectors got brushed and brushless motors? I'm currently using tekin 4mm banana connectors, but there a tad on the long side. Also, they are not readily available at my LHS. other good points to consider: ease of soldering, resistance, etc. this is got 12awg wires, only between esc and motor. I have a few esc's and motors I like to switch out, so I want to standardize on one connector.

Thanks!

I like the castle creations 4mm bullets for my brushless setups and on my brushed setups I use hobbypartz.com's 3mm bullets for their price and they work well with low resistance

I use Castle 4mm on just about everything.

the best bullet connector is no bullet connector. solder it straight between the two surfaces

I use no name 3.5mm connectors. $2.50 for ten pairs (including world wide shipping). They're short and can handle ~50A.

+1, I don't use any more "removeable" connections than absolutely needed, everything else is soldered.

Yes, I agree no bullet connector is lowest resistence, however, if you read my OP, I'm asking about bullet connectors since I swap out ESC's and motors frequently, more often then I want to break out the solder station.

For you guys using the 4mm bullet connectors, are you using that for 12AWG wire or smaller guage wire? My LHS carries only 5.5mm, which sounds a bit on the big side.

x2. Direct wire & solder = zero failure

I've received more than one used motor with a Deans attached to it.
I always swap them out but what do you guys think about using Deans for motors?

i first used a deans plug on a motor then soldered bullets to it so i could switch them in case motor was running backwards, but then just went with bullets on motor to match ESC....sucks having to un solder when you need to switch wires on motor to run it different direction then just unpluging bullets to do same thing ....like every thing else there are pro's and con's.........bob

I've been thinking of switching everything over to Deans just for ease of use.
Like agent00111, I swap stuff around a lot... but I did finally get a 3rd esc so hopefully I won't have to do that as much.

4mm Castle plugs on everything small I assemble. Female on the ESC, males on the motors. They are indeed hard to get, I have to purchase them in bulk by the thousands so I have a good stash for ESCs and motors.

All my stuff has deans on it (except for the brushless stuff). Never had an issue.

I've also never said to myself "Dammit! If only I had soldered that connection I would have won!".

I really like deans connectors, and would probably use that if i was switching only between brushed motors, but with brushless and brushed motors, bullet connectors make a little more sense for me.

Yes. No way for anything to snag and unplug itself. I come from the racing side of 1/10 rc where NO ONE uses bullets, other than those villeneon systems.

Your battery, with a Deans between the two, will supply the esc with more power than the esc supplies to the motor. So Deans should be fine between the esc and motor.

I want to say that a lot of people will have more success numerously soldering wire to motor tabs than they will have if they solder wire to bullets even once. That is much more difficult

One little zip tie takes care of the snag issue.

I can understand direct wiring in racing, but I don't really see a tremendous benefit in crawling. Heavy amp draws are way less frequent. The use of 800mah 40c batteries and esc's designed for 1/18th scale vehicles proves that...
