Hehe that won't be happening Igor, since they mark the chassis at the start of the euro's, so no switching cars :-) Ask Bob about the B4 vs Losi! (altough I admit I was impressed by the insane amount of steering these B4's had when simon & danny were driving Lee's and Tony's cars...)
Lee, do you mind sharing your setup from 2WD? I made a site where I put some setups online.
http://www.rc-offroad.be/setup.htm There's one from you already, but it's very incomplete.
Also did you run with the same setup all day, or did you make some small changes to compensate for the changing track?
And finally, did you run new rear/front tyres each run?
