Welcome to Tamiya Club bud, the most awesome club ever. Great story about your king Cab. I know what you mean about the racing thing. My first RC was a lunch box and i tried to take that racing, and never won anything but it was really good fun though. i put a huge motor in it and pretty much never used the front wheels as it was on its wheely bar most of the time, which made cornering entertaining :-)
I recon with a good strip down clean and re-grease your King Cab will be great. I really love these trucks ive bought and sold 2 of them now and remember when i first got into to RC this was my favourite truck ever. Im about to buy my third as i just cant live without one.
Hope you enjoy the club as much as we all do. They are a fantastic bunch of people, and allways there to help
