just put one together myself, things I noticed:

Drag link from servo to steering arm pivot calls for approx 1/16th in manual, for full lock to lock 2mm is needed (team guys are using a blue spacer, I had 2mm spacer)

Bolts for transmission do need thread lock AND double check after first few runs. When you assemble it, do not crank down just snug, tighten after tranny is run a bit.

AE springs are icky, especially green rears. I have converted to losi big bore springs. Losi orange in front, yellows or pink in rear. Used traxxas spring holders up top to retain, used losi 22 spring holders on bottom. Very smooth, could tell they were better right away with no other changes.

Do yourself a favor and get what ever setup works for your track, before the build, all anti-squat/shock pistons/toe blocks come in the kit to set it up from the get go. Easy build, great fit and finish, great design.

I picked up all the carbon parts, +8mm chassis. Car drives like a champ, great fwd traction and steering, especially on the gas in sweepers. You can drive it in and out of corners quite well, my biggest complaint of my 22.
