Can you help me? I'm new to all this. I got an RC truck at a garage sale and it runs like a bat out of hell. The owner said it was his sons (who is deceased) and doesn't remember anything about the truck. It needs a little TLC and new tires/rims, but I don't even know what kind to look for. There are no markings, numbers, etc. anywhere. It measures 21 1/4'' long by 17 1/4" wide, is a 4x4 and gas powered. I've been on line for hours looking for anything similar, but obviously no luck. Please help if you can.
