|  RC4WD XR4 Help
Well I had gotten the XR4 radio system a few days ago and today I had what I thought would be a great idea. It turns out that wasn't the case. The XR4 is powered by 4 batteries, although there's room for 8. I had the bright idea that I would make the radio be powered by 8 batteries. So after a little while, the radio stopped working, only the backlight on the display worked. So I took the radio apart to see if anything might have shorted out. I even switched back to the normal 4 battery config. Nothing, but when the radio is on for a few seconds, there are 3 chips that get burning hot (circled below). I'm pretty sure that i just trashed it, but any help would be appreciated, thanks.   |

Why would you try to run it off of 8 batteries when all that's needed it 4?

I would have worked if you would have wired 4 batteries in series and 4 in parallel. You would have doubled the run time. However you didn't and you just pissed away money instead  |

Somewhere in your radio you let that magic puff of smoke out... Yup, you should have wired the other 4 batteries in parallel instead of series. Live, learn, buy new junk... |
