My crashes may sound bad. But all they really are is just a decent wack to the sweeper, I'm sure that people have seen/had worse crashes but it may just be the way I hit the pipe. Or mabey its just that I'm trying to take too tight of a line (but the car hopping on the old wrinkly carpet doesn't help much either ).
I would reccomend the speed merchent rev. 3 over the carpet knife 3.1 (I don't know anything bout the 3.2, I'll go check CRC's site to see what they changed). Mainly just because of the side links, so far I haven't broken a speed merchent link yet. And don't worry bout the speed merchent not having holes drilled in it for the servo mounts. I've recently mounted my servo flat on my carpet knife because the servo saver would hit the body anyway so I couldn't get the body down low enough. The rev. 3 also has an adjustable battary position. I would of chosen the rev. 3 but I was so paranoid bout not having the holes in it for the servo, but mounting the servo is always better, unless you have to remove your servo often. You get a lower CG, less weight, and you can get your body lower in some cases. Hope this helps for anyone getting into 1/12 scale.

Here's some good news about my carpet knife. I installed some motor shims in the rear foot ball thing and so I got my rear pod to sit level (for some reason one side was about 1.5 mm lower than the chassis. And I got the tweak "perfect" , so to speak. Im sure it could be better. But its as perfect as I can tell, and the only way to get it better would probably to spend about 2 more hours screwing with it.
