I have been lurking in the forums for a while, and have been really impressed with the r/c community here. I am a returning to r/c after about 10 years. I have an Associated RC10B4 SE RTR buggy that I got about a month ago. I use it just to run around the grass in parks and such. I have been really happy with its motor performance and handling. It has the stock 15T motor and I have been using 2 different 1600 mAh NiCd packs and a new 3800 mAh NiMh pack.
The first time I noticed what I will describe was when I used the NiMh pack. When I plugged it in and turned on the power, the throttle was reversed, but the steering was normal. At this point, I probably should have thought more about it, but I just changed the throttle reverse switch on the transmitter.
After about 5 minutes of running, it started hesitating (glitching?) while accelerating. It got worse over the next minute, so I drove it back toward me. I noticed smoke coming off the end of the motor and a smell of melting solder. I then saw that the solder on the yellow terminal (not sure if that's + or -) on the end of the motor was liquefying, and the motor was so hot I couldn't touch it without risking a burn!
I touched up the solder and checked the spacing between the pinion and spur gears. I set them with a piece of paper between them. I tried running it with both of the NiCd packs today, and the throttle is back to working like normal. After about 5 minutes, the same symptoms appeared both times.
I'm not sure what to check now. It doesn't seem like the gearing should be a problem since I haven't altered it. The packs have all been very warm, but not so much that I couldn't hold them. I'm note sure what to do next. Any help would be much appreciated. Thanks in advance,
Maurice
