Easy RC Car Controller Mod

Introduction: Easy RC Car Controller Mod

In this Instructable I will walk you through the process of converting a Traxxas TQ radio transmitter to run on a rechargeable battery pack. This can save you hundreds of dollars! If you race consistently in any competitions or you just like to have fun at home you know it costs money to buy batteries for the remotes. Often, it is the vehicle that needs its power source replenished, but this remote is very high range and runs the batteries down pretty quick. In strenuous studies,(counting the batteries) I came to find that the remote runs on the same voltage as a replacement battery pack, 9.6v or eight batteries. The goal is simple, Stop Paying For Batteries! All you would have to do once the transfusion is complete is charge the battery pack and plug it in!

Step 1: What You Need...

This is very simple, like i stated in the title. You need; a ruler, a knife, a Philips head screw driver, a battery pack, a pare of wire cutters, a pare of dikes, a sharpie(not pictured), a female plug that fits the battery and the remote.

Step 2: Cut It...

Place the female plug against the plastic right above the bottom screw and then trace it with the sharpie. Then unscrew both halfs and cut along the line with the wire cutters horizontal and the dikes vertical. The cut should end up like this or if your good, it will be even. Take the knife and clean it up. Make sure the plug fits.

Step 3: Almost Done

Now, solder the leads from the plug to the corosponding leads on the remote making sure the originals and the new leads are connected after the heat is apllied. Then put the side back on and your plug should sit in the hole ontop of the screw. Put it back together and your done! For a little added strength, run a bead of hotglue around the opening.

    Nitro or Electric? I have the original electric one with the manual speed controller and I like it a lot. I upgraded it to the XL-5 but haven't had a chance to drive it because I have had to take parts off of it to put on my rustler VXL because I crashed it so many times. LOL.

    Nice instructable. Just some thoughts... If you were to remove the plug from the battery pack and fit one of the round DC connectors, where the outside was negative and the inside was positive, and then fit a socket to match, you can leave a set of batteries inside the controller that will run when the external pack is unplugged (this is because the socket has a switch on it that breaks the circuit from the original batteries and then applies power from the external pack when it is plugged in). That way you could still have a lightweight controller if you needed to go to the car for some reason, and then return to where you were and carry on with the larger pack. Also, you dont mention what to do with the larger pack you have fitted, ie is it just dangling from the socket? You could fit the socket as I mentioned above and have a long lead with the pack sitting on the floor (or in your pocket......but not in with keys or coins !!) or you could cut the plug from the battery pack you have, and extend the lead on your battery pack to reach your socket.
