I finally got my XO-1 running! All I can saw is woah! This thing really is insane! I hit 72mph and haven't even passed half throttle yet!

Anyway one question I have is, I am having a lot of noise coming from the car. It sounds like it's coming from the body. However, I can't seem to find anywhere it might be rubbing. It's pretty loud and is like a bang... bang... noise. Any ideas?

Also, has anyone figured out how to tighten up the front end? The wheels wobble a bit when turing. I can't imagine how much they wobble at high speed.
