Yes, I understand that the pivot or side links wont move freely after a hit or crash. What I am try to get at is the lower half of the pivot block distorts under the pressure exerted by the chassis mounting screws. I guess the plastic is too soft and causes this distortion. I assume the Xenon pivot blocks are made from a tougher plastic and is more resilient to distortion. Of course the Rev8's pivot doesn't bind... because the plastic pivot housing and the main block are individual pieces. You can crank down as hard as you want on the two screws holding down the carbon fiber assembly. As long as you don't crank down on the two small screws that assemble the plastic pivot ball housing.
That's a setup I would like to have.

Am I correct in assuming these trackstars are the same things (at least the look) as what SMC is selling?

I will say they are not the same. I have both brands of ESCs, I do not know who makes the ESC for SMC but it has its own thing going; all aluminum case, different programming parameters and is lighter than the Trackstar.
Yeah. I'm not expecting top of the line performance from a $40 ESC. I have a friend who used to race with me that wants to get back into it so I'm putting together a backup car I had and need something to go in it. Being inexpensive is more important that world class performance for me.

i like orion packs i started with an used one that was puffed and was keeping up w/ the fast guy at our track only reason i lose is because of cleanliness, but fast laps are usually close like within .2-.3 of a second which is more of my line which translates to being a few seconds off of his overall run. i just switched over to my used crc, which is kind of cracked around the terminal part but it isnt puffed. it's a 90c but i havent seen much of a drop off. but i will be buying new batteries here soon for 2s and 1s

In the past I've always had good success running Futaba 9650 steering servos. I'm currently building up a new car and, while looking around to order up a new servo for it, I noticed that Futaba still makes the 9650 but they also now offer a 9670V servo that is listed as specific for 1/12th scale. Can someone please explain what is the difference between those two Futaba servos? The other one that looks pretty good is the Spektrum H5020G. Has anybody on the thread had experience (good or bad) with one of those?
The 9670SV is a high voltage servo that can accept 7.4V. I wouldnt advise using this servo unless you know your ESC can deliver and your receiver can accept 7.4V.
Another thing is this servo uses all plastic gears. One bad crash and you risk stripping the gears.
Savox makes pretty good and inexpensive mini servos applicable to the 12th. The only down side with them is the output shaft does not necessarily align with most typical mini servos out there. You would either need to find a chassis with slotted servo mounting holes or widen the servo mounting hole on the chassis to ensure the output shaft of the servo is perfectly centered.
