Here's my gears after 4 tanks on Sat, look like new. After reading this forum I did all sujested upgrades and the only thing that happened was a wheel hub pin fell out. Luckly I had spares from my 5b so a one minite fix and back on the road! I'm really impressed with this rig, it's not a racer like my mcd but it seems to take a beating more so than the mcd. Two thumbs up on this truck!
