The tlr kits may be great, but whoo wee their manuals suck. I have never had to guess more on what goes where in my life. While the cars may be very close in performance, the manual had to be made by either the smartest or the dumbest person @ tlr. Tekno will go together easier everytime. I know you'll disagree with me on this, because duh, you've built them before. You know where most everything goes. But a beginner or even a pretty good racer who's never owned tlr would tell you it was anything but a well thought out build process.
