I was mounting the spare tire to the bed of my scx10 with the body still mounted on the chassis....bad idea! When I drilled the hole in the bed the bit went through too fast and drilled a hole in my lipo! I didn't noticed until I saw the smoke, I grabbed the truck and ran outside then pulled the battery. The pack got warm for a minute but no fire. To make things worst I sold a couple of lipos last week, now I have to use a nimh pack
