Default Castle ESC missing motor connectors

So my first post. I have been searching and reading for months now. I am not new to RC but so much has changed! My first setup was an RC-10 with a manual speed controller years ago then later down the road a Blackfoot with an old Novak speed controller. From lipo batteries to drag brakes and BEC's.. It's all new to me. I have been doing lots of reading!

But any way on the question. I finished putting together my rubicon SCX10 and all the electronics have been rolling in. Today I got my sidewinder, HITEC servo, and 35T brushed motor. I was excited to get everything wired up but ran into a couple problems.

First. The ESC does not have motor wires. Just the female bullet connectors and none are labeled. I can't find anything on which two I use for a brushed motor.

Second. The motor I picked up has male bullet connectors but they are two small for the ESC. I have no local hobby shop so everything is mail order. I was hoping I could go to ace hardware to get some wires and bullet connectors to make an adapter. Anyone know what size connector to get?

Welcome to RCC!

You can use the black and red wires on the ESC for brushed motors. Iirc the male bullet connectors you will need are 4mm. Make sure you also set the sidewinder to brushed mode. You could take the ESC to your local radio shack and I'd bet they have some connectors that would work for ya.

Thanks, but the problem is the motor side does not have wires (red, white, and black). Just 3 gold colored female connectors that are not labeled. The motor I have has the wires pre soldered with male bullet connectors but they are too small for the ESC.

You should be able to use two of em. Iirc the outer two. One the sidewinder I have the middle is the white one.

Check out castles website they should have all the info you need. You need to use the correct bullet connectors and wires. You will have to order it and solder new leads into the motor.

I just cut the bullet plugs off and soldered the red and black wires to their motor tabs and ran it. The wires are on the shorter side but it works great.

The Castle Sidewinder don't always come with the same config.. If you buy it in a combo with the motor, the ESC will not have output wires, only female 4mm bullet into the epoxied casing. The motor has the wires with the male plug..

But I think if you buy the SW3 by itself, it will come with output wires instead of connectors..

I can be wrong, but I know that you can have the 2 types!

Normally, in the box, (if brand new) you should have the male 4mm bullet included to use on a non Castle motor (since Castle motor comes with their 4mm bullets)

You can solder direct to those posts if you cannot find the proper bullet connectors.

Thanks, that was going to be my next question. I wasn't sure if they could take the heat or not. I would much rather solder a wire to them than get a connector.

I usually use connectors, just easier to change out a motor, instead of de-soldering/soldering..... Especially if I don't have access to a soldering iron out in the field. But that's just me.

Cheers,
Wade

Thanks for all the input. I ended up making a new set of wires from the ESC all the way to the motor. For the ESC I just used Banana connectors. Between the ESC and the motor I used 3.5mm bullet connectors. Someday I may order the beefy Castle 4mm bullets but the ones I am using seem to be fine.
