The car was properly 'tweaked', however I had noticed from day 1 that the chassis is not completely flat, maybe the rear end is raised up 0.5mm on a flat board. The only thing I could not change was the roll bar, which losi stupidly left out of this kit. And plastic hex's??? losi.... come on mate!!
my rant for today
I feel your pain. Ever sense the early 2000's Losi's quality has not been the best in my eyes. I hated the the cheap plastic wheel hex and not a sway bar. That is just being cheap. On a positive note. With all the slop and poor fit building the car. The car is fast, very fast. i mostly ran indoor carpet but this past summer we had a parking lot track. I am not sure what setup you went to but one thing I noticed was my indoor carpet setup worked pretty well outdoors on a large track. I had to make some some changes like running a low roll center in rear and reduce camber gain in the rear. Other than that the car felt good. I posted my setup a few pages back. Maybe you could compare it to your setup and maybe get some ideas.
