Default Gmade wiring help need

hey all, I have a gmade stealth coming tommorrow and need some help on wiring it up. I have a sidewinder ESC and an emaxx ESC. Which one should I use and if I run the sidewinder how would I wire up the 2 motors? I'll probbably run rear steer as well but I know how to do that. Would I be better off running a rear lockout and use dig instead of rear steer? I have a 2.2 and a 1.9 but have never had a super before. Any help with pics would be awesome thanks in advance. Dustin

What radio are you using ??? You can have both rear steer and dig, if you have enough channels.

Only a 3 channel for now. I will be going more later if I start comping it.

If you want to run two motors on the Sidewinder, all you have to do is wire up the motors so they are in parallel with each other. There are a few ways to do this, but basically what you will do is take the one positive motor wire off of the ESC and split it two ways. Do the same with the negitive motor lead. What you are doing is creating a y-harness, and then each motor gets one positive and one negitive lead, like normal. I make my own y-harnesses, as needed, by soldering three pieces of wire together. Strip the ends and arrange them like a Y. Solder that together and cover it with some heat shrink. Do one for the positive wires, and one for the negitive wires. You can put the proper plug on the ends of the wires to match the ESC and then solder the other ends to the motors, or add another set of plugs so you can separate the motors from the y-harness at some point in the future.

You could also solder the positive and negitive leads, from the ESC, to one motor first, and then solder a pair of positive and negitive wires off of the first motor, and run them to the second. That does the same exact thing. Most motors have two sets of terminals or lugs that can be used for this, if you don't feel up to trying to solder two sets of wires to each terminal together.

It's easy to do, if you are handy with a soldering iron. If you can't solder, then there are still other options. Tower Hobbies stocks some pre-made y-harnesses of different types that could work as well.

Ok , I followed the awesome advice here and built myself a Y harness. The rig is alive. Now it is having some issues with the motors. The rear kicks out very easy and only the front is pulling. Is this called clod stall? I am running a sidewinder with 2- 85t motors. I have a 3cell lipo in it as well. Any more advice on getting rid of the axle kicking in and out? It seems to do the opposit when in reverse . Thanks guys

This could be Clod stall, if the rear motor stalls on an uphill climb. Front motor stalls on a reverse uphill climb. What kind of gearing are you running? It helps to go low. Try a 8 or 9 tooth pinion on the rear and front. Some guys like running a couple more teeth on the front pinion, then the rear, in order to try and even the motors out on uphill climbs. 85T motors seem a little on the high side for most crawlers. I would suggest some 55T or 45T motors, geared down more, and on 11.1 volts, they should really rock. The 85T motors with taller gearing are probably struggling with the load. 85T motors really aren't any more powerful then the 45 or 55Ts, just because they have more turns.

Ill check the gearing and see what it has and change the motors out, Do you think I would bennifit by running the esc to the rear first then to the front instead of the Y connector I made

Some people would have you believe that running wires to the rear motor first will help cure some of the stall, but I say it's non-sense, unless you are running wire that is to small to carry sufficient current. The fact of the matter is that wire can be assumed to have little to no resistance, at least in the short lengths we have on our crawlers.
