To expand on the last one, in-line doesn't mean everything is perfectly centered. If you have the wire routed slightly to the left rear of the car (you do, that's where the motor connections are), you have an imperfection in weight.

Less than 20gr off to one side of the car or the other? I wouldn't worry about it.

CC as in closed cell foam?

Undo those changes you made to the camber links and wheelbase.
I will try that. Thanks.

I like to use throttle expo on my radio as a traction control on all my mod vehicles. By adjusting the expo you can increase or decrease the trigger sensitivity but still have full power when you punch it. Even a sensored mod motor delivers power so abruptly that it can be difficult to tame in 2wd. I just built a new kit and put a 7.5 in mine and I had to immediately adjust the expo for the track conditions and my shortie lipo light weight setup. Try it, its one of my speed secrets I use on a regular basis. When other people are complaining about traction, I've alread made a adjustment to compensate and they ask what tires I'm running I say MC ions with buggy grip.

I actually did mess with the expo. I'm at -2. What do you run yours at?

Ya I've seen it but I'm still not convinced mid motor is better after the experience I had with my 22 considering B4.1 and 2's where running circles around me. I literally tried everything with that car in both configurations and my laps were faster on my first 2 batteries with the b4.2 kit setup.

The centro looks legit but hows it doing in Tacoma? I heard scotty has one.
Also is the centro running standard saddle packs or the larger 1s packs?

I liked the shaved brace/ c hub even on a lower traction surface, it just feels better to me

if your running you can also run "traction control" or throttle speed, with the 4pk's go into your menu and then if your on menu two press plus and then go into throttle speed, pres the plus to get to setting three, go down and set the first to like 75% and the 2nd at like 90% and the third at 100% unless you want to limit your speed, dont change 3

I didnt. The cars rear end stayed too flat and skated a lot.

I weighed it before the centering kit and it was closer. I thought it was supposed to center weight better, maybe i'll try the receiver on the other side. Also why is the front off more when basically everything in the front should weigh the same? Can I make changes other than adding weight?

first off this isnt a touring car. Look where all your weight is (in the rear motor, battery, receiver, wires, diff,tranny etc, the only thing you have up front is your servo, and steering rake

Measure your cars weight left to right (which is what the centering kit does makes it more even left to right) if they are with in about i dont know 10 grams your fine, you can play with wire placement, or moving your transponder around, but if its close your good, i doubt youll notice a difference between moving the reciever and transponder around unless its center lined, compared to on the outsides, just run it see how you like it

And i think its a matter or preference, we have big sweepers, and wide corners at our track, it worked well wet or dry, but it also depends on the rest of your set up, i didnt bother changed it back to the a tower because i thought it worked well 3rd time racing the buggy and i got first or 2nd i dont remember

Also I took it apart and cleaned everything so I know its not dirt causing the problem, also checked shock collar height with calipers. Any help would be great.

Ok so I just weighed my B4.2. Bit of info, I also just installed the AVID centering kit (didn't weigh it before) and also went centerline with the ESC in the tray. My RX and transponder are on the right side of the car. I'm running a shorty.

LF - 206g
RF - 220g
LR - 459g
RR - 463g

I haven't measured my spring collars yet, I'll do that shortly...honestly I should have cleaned it a bit first too as there is some dirt build up. Also noticed that my LR shock is leaking where all the others are pretty good.



Edit: so I think I need to rethink my measurement technique as my total weight by adding those numbers is 1348g and when I measure the total weight it is 1485g. And to add to that...does it make sense that I'm at 1485g without the body? Thought I should be heavier...didn't bring the body to work so I'm not sure what it weighs.

I would think that would be ok.

Here's the setup I used this past weekend. Outdoor, dusty 1/8 track that's pretty bumpy. I had made several changes here and it worked VERY well as opposed to the traction I had been having. I was all loose in the back as you describe but with this setup I felt pretty locked in and my times improved as the day went on and I got used to a revised track layout. Wound up 3rd in the final race. I guess my thoughts would be more rear toe and some additional negative camber as well as making sure you are transferring weight to the rear wheels.
