Wiring 12020 ESC question
 

Quick question: I have the 12020 controller coming. Does this model use two wires for each motor phase? And if so, how do people stuff the pairs together in one 5.5mm connector so it's not crappy looking? I don't have the ESC yet, but if I need to get other parts, I'd like to know now.

FYI: I did a search and didn't come up with anything relevant.

Yep it does. I took and soldered one in and one outside the 3.5 plugs I used. I don't know about the 5.5 plugs.

OK, thanks. That's kinda what I figured. If one wire fits in a 3.5mm connector, maybe two can fit in a 5.5mm connector. I guess if it doesn't, I can always do what you did. Does it look OK with one of the wires soldered to the outside of the connector? Maybe I'll solder the two wires to a short (1") piece of 8GA or 10GA wire and then that to the connector. A piece of car amplifier wiring should do the trick...

Hey, I got a 9920 with 4.0 to the battery and 3.0 to the motor. How do I get the two battery wries to hook to two battery packs with deans??

What's "4.0" and "3.0"?

4.0mm gold connector 3.0 gold connecter

whats your battery configuration? The one I used for that exact esc is this:

If any questions, ask.

I have the 7 cell hump pack. How do you post pic's sence they changed the fourms?

Or, if you have a website and they allow direct-linking, use that. Also, many ISPs give you a little space along with your internet access. That's what I use.

3mm connectors sound small. You talking the 3.5mm. You need to change the deans or the plugs.

Yea, deans would be best.

but thats to the motors. That is what schulze reccommends and uses, and that is what lehner uses.

My lehners use the 3.5 mm and the schulze to. It is hard to modify the stuff cause it was made like that.

mmdooley has 3.5mm on his motor wires...

My battery bridge adaptor uses Deans just because that's what I used on the battery packs, but the connection between the bridge adaptor and the ESC, as well as the motor wires, will be using the 5.5mm connectors.

The only downside to using the individual 3.5/5.5mm connectors is that there is a possibility that you can reverse the polarity if you are not paying attention since there is no key.

Also, try to put the female end where there is power to help prevent accidental shorting on the frame or whatever. The male end should go on the load since it won't hurt anything to short those by accident. I also plan to fabricate some type of shroud over each connector to completely insulate them from anything else, yet still allow easy removal.

both the wires will fit in one 5.5 mm plug. the socket part already is on the motor.

Here's what I have.<center>

You need to make a deans on the esc or make a adapter of the deans and plug adapter.

Yea but how do I make 2 wires into 4 wires???

Here you go;

Thanks, that's in series right? Right now I have my Titan's hooked up so I can work out all the "bugs" lol. Right now I am having t
trouble getting my MX3 working. It want's to run backward:confused: Anyway here's some pic's

P.S. I know the wiring is junk but I will fix that when I put the 9920 and the 8XL on.

Yep in serie's.

You need to reprogram the evx, or reverse channel 2 on the transmitter.

Reverse channel 2??? Not sure what your talking about :confused:

You got channel 1 for the steering and channel 2 for the throttle. If needed you can switch the direction of both of them(like left - right become's right - left, forward - reverse becomes reverse - forward). This is handy in a situation like your's.

Look in the manual. Very easy to do.

Oh yea I tried that and the motors run wide open. Then I tried going threw the programing procedure again and no luck???

Yeah that is correct. After you reverse the channel you need to adjust the neutral of channel 2(trim).

Ok, Thanks for the help :027: Does it lose programing when the batterys are unhooked? Because it was working and then it quit :confused:

A little off-topic, but I was looking at the pcitures in your post and was wondering if there was a reason why the tread on the front and rear tires face different directions?

No I just put the tires on to make sure there were no odd sounds comming from the drive train.

mmdooley, very nice truck, but do you really think its safe to run without bumpers?

I have not finished it yet. But I do have the FLM skids on the front and back will that not give me some protection??

well if you hit it hard enough, it will just bend and could damage a part.

What would be good bumpers for this setup??

stock. also, if it runs backwards the best thing to do is flip the diffs or reverse the tranny driection. most brushed motors wont like to run in reverse all the time.

It's the evx that's backward because the wheels roll forward at a slow speed. And when you push the throttle to reverse it will roll the wheels in reverse at very high speed. But I got it better than that. Right now the wheels roll forward at high speed but I am pushing the throttle in reverse.

Why is that squee? The only thing I can think of is if the brushes have been "broken in" in one direction.

Yall are losing me, I have the hybrids and as long as they are running in the same direction they are right,right???

The only thing that will limit the speed of the titans is the evx. It run's faster in forward than reverse, so flipping the diff's is a bad idea.(you are right that brushed motor's do run slower in reverse due to the brake in, but the evx is slower) Flipping the tranny would be a 3rd option, but the real problem is the radio setting's. Reverse channel 2 and adjust the trim, then re-set the evx. It should hold the setting's, if not there is something wrong.

Nice truck there! What servo will you use to turn those wheels??

The 8XL is a good choice, btw!

I hope you get it going soon.

Another thought: If you look at the brushes of the Titans, you can see why they have a prefered running direction.
