Hi guys, I have 2 LST2's with E-Maxx tranny's. One has a 9Xl / MM on 4s,set up for racing on a small tight track and the other one has an 8XL / Quark 125 on 4s both have single speed (2nd gear only) conversions, with good traction both will wheely, but the 8XL violently flips over. I find 1st gear pretty unusable.
