Hey guys I am new to R/C cars and am having some trouble. I just bought a used car so Ill try to give all the info I can.
Car: Team Losi XXXT Graphite ( I think they call it the MF2 Racing Truck Kit)
Speed Control: LRP IPC Digital v7.1
Controller: Sanwa MX-3
Airtronics Super Micro 3ch receiver by Sanwa
Battery: Venom 7.2v 5000mAh NiMH
Engine: I am not sure because I dont have an allen key to take of the cover blocking it.
Anyway here is my problem. I bought the car. I used it like 2 times (2 charges). I used it another time. When driving it just stopped. I noticed one of the wires going to the engine came off. I soldered it back on. It happened again and I soldered it on. Then it did the same thing again, except the wires were still connected. I am not good at soldering so I figured maybe it was a bad connection and let me just bring it to a shop. They said that the brushes on the motor got stuck. Not sure if that is related at all and they just free'd them up. I also had them redo the soldering because mine wasn't so good. They did a great job so I figured I'd be fine.
I went to use it again today. Put in a full charge battery and it was running great. Then all of a sudden its acting like the battery is dead and going like half speed after 5 minutes. I thought maybe the battery wasnt full but it was. I went to drive the car back to me and then all of a sudden it picked up and had full speed again. Ok dont know why that happened but its was fine so I kept riding.
As I am driving I see a trail of smoke behind the car for like 30 feet and then the car stops. I take the body off and BOTH wires came off of the engine and it smelled like burning.
Why is it getting so hot and smoking and desoldering the wires? Is the battery to big (voltage? or something else)? Is the engine shot and worn out?
Any help would be great and if you need anymore info please let me know. Thanks
Not sure if this is related but on the slipper clutch on the spur gear (not sure if I am using the right words)
the nut on the spring thing is tightened all the way down. I am guessing this leads to no wheel spin at all. Could that be overheating the motor?
