Futaba FX10 All Terrain RC Car

Hi there.
We just picked up an old remote control car and when we drove it it started smoking out of the back. We took a picture of the piece that started smoking but I canít seem to post a photo from my phone. Itís a small rectangular box that is about 2 inches long, an inch deep and an inch wide, with three wires attached to it. It says 0.3 ohms x 2 on it ( at least I think it is ohms, itís the horseshoe sign.)
thanks,í
David and Noah

Welcome to the forums.

Yes.... that is ohms. Sounds like a resistor block.
Not all phones can post pictures here...... How-to-insert-pictures.

Resistors themselves don't fail and smoke.
Something else failed and caused a very high current flow through the resistor.

It sounds like you let the magic smoke out of the ESC. If you follow the wires one probably goes to the battery. Another wire to the motor and the last wire is the BEC to power the receiver and steering servo.

Thanks for the help. I'm away and don't have the car in front of me, but I did consider that something else other than the resistor was causing the smoke. All 3 wires are going to a unit that is not the battery - not sure what it is. Two wires run from this mystery unit to the battery.

I just looked up that car. At least 30-35 years old. It has a brushed motor with a mechanical speed control. So, it is possible you smoked a resistor. I found nobody that had control or electrical parts so when something electric on it fails everyone converted it to modern electronics but that requires spending more money than the car is worth so it's something you'd only do for sentimental reasons. But, if it's just a resistor that would be easy to replace. Some good pictures of the component that smoked would be a big help.

Hi there. I think I figured out how to attach an image. The first one shows the white rectangular piece that is smoking. The second shows where it is located (near the back of the car).

I actually have two of the white rectangular pieces and have swapped them out. Both end up smoking after driving the car for a minute or so.

What battery are you using to power the car?

Weird, the photos didn't seem to go through.

The battery pack is 8 Ni-Cd rechargeable C batteries.
