Words Erich Reichert

As drivers progress within the RC hobby, there comes a time when it’s necessary to upgrade motors and speed controls to go faster, harder, and stronger.  If you started off with an RTR, you’ve most likely lived a peaceful life with your RC vehicle; going day in and day out enjoying it’s pre-wired perfection without giving it a second thought.  Now that you’re making the leap into upgraded electronics, you’re going to find that your newest challenge will be getting everything installed. Fear not, with just a few easy steps and the right tools, you’ll see that it’s easy to solder.  It’s so easy that, with the right tools and supplies, anyone can do it. Let’s get going.

The wires should be cut just long enough to reach to the component to which it connects. Add about 1/4 inch extra just to be on the safe side, but not too much more.

The best place to start is with your new motor and speed control (or other component) in place so you can measure out the wires needed.  You want to make sure they’re long enough to reach, but not so long that you have a ton of wire all tangled up. Plan out the path for the wire and consider how they will be attached or held down to the chassis to stay out of the way of moving parts and the drivetrain, keeping motor and battery wires away from any belts or moving parts that can damage them. Route the wire along the path it will span in the car and allow about another 1/4 inch or so just to be on the safe side; a little extra never hurts. Measure each wire individually and cut it to the proper length with a hobby knife or pair of wire cutters before moving on to the next one.




Use a hobby knife to strip the wire without losing any strands of wire inside.


The exposed portion should be roughly the same size as the contact area to which the wire is connecting.

Once you have all the wires cut to length, strip off enough of the insulation to produce a good solid contact. The length here will depend on the size of the surface the wire is attaching to but the goal is to strip approximately the same size as the contact area to ensure maximum coverage. To strip the insulation, many people use their wire cutters and I’ve even seen people use scissors. However, to get the cleanest strip without damaging any of the strands of wire inside, I use a hobby knife. Start at the bottom of the blade and carefully roll the wire down the blade, scoring into the insulation. Once you’ve gone all the way around, pull off the cut piece and discard it.
