I also like the looks of the 5b - but would never get a 2wd one. If I were to buy a large-scale truck someday, I'd be interested in a Losi 5ive-B (if they ever make one) brushless.
gonna cost ya though. 1500 for losi.minus 350 for gas junk. plus a grand for brushless plus the aja kit. OH then u need a dual servo conversion and a few minor hopups :-) oh and its worth every penny!
