Compared to my Kyosho now, I thought the Losi didn't have much steering. I was always struggling with the handling, people could out-turn me everywhere and I wasn't sure why. Make sure your servo-saver is tight enough to not cause handling issues. I would recommend getting some "condoms" so the center drive pins do not come out. Get the 3-3 rear toe plate. I ran the King Heads hard clutch shoes and the regular losi carbon ones. Like others have said, loctite the shock shaft screw, that lost me a race last year...
Hope that helps,
