Wow! Thanks so much for the explanation. Your track is exactly like my local one. Ours won't hold water during the day also and grooves really nice at night. I can't wait to try your setup on the track. I have been having issues with traction through corners but have tons of rear traction. I am going to switch to the proline holeshots for the front because I am using the ribbed and that could be one issue.

For the ones that are running 17.5 would there be any changes to your setup that we should do?

Anytime. I try to share when I can.

Where in the corner are you losing traction? Always good to understand what is happening to the car's attitude at that point and what items add or remove rear traction at that time.

Nope. If people run a 3 gear, they *might* want to try half degree inserts in the rear hubs or 21mm droop (SORRY sorry, I mean STROKE, sorry...) in the front for some more rear traction, but that's honestly just a guess, and those two things really change the car too.

What we do when we run the track wet is run an 1mm HRC kit and drill a third, inside, shock mount hole, on the arm as well as a lot of droop in the front. Got the idea from some local AE drivers. I run long rear links all the time regardless but I would think that you'd want a shorter rear link for lower traction.

I am losing traction through the whole corner if I try to keep it under power like a lot of the guys do at the track. I have to basically coast around the corner and right when I can start to straighten out I can get back on power again.

I am running the 3 gear that came with my car. Everything on my car is stock setup besides removing the brace behind the servo and the brace between battery strap. I was thinking of moving the esc forward along with the battery to help with the forward bite. Right now I am running the esc and rx inline.

Hoping I explained the issue decently. I am still learning

I thought so too, but when I tried the shorter standard link, it added a ton of traction in the corner, like it was too stuck, and wouldn't rotate, and then it was more loose getting on power. It just made the car feel pushy and loose.

What kind of corner? Large, small, fast, slow?

Well, obviously the first thing to check is ride height, tires, differential, and camber settings. Having a relatively tight differential is key on low traction.

They have done all the trial and error for you for the surface you will be running on, the gear ratio that works for them in 17.5 (this I found will still require some tweaking as everyone's driving style differs ever so slightly and how you want that power to hit is pretty important).

I would get the car ready and hit the track, pick the folks brain you see running good lines and their car seems dialed, rotates well, has good jumping manners and seems to be dialed in already. Most of these will be happy to share their setups, rarely do I find some one unwilling to help me out at the track I run at.
Thank you for the info! I am hitting the track as soon as I put all electronics together. I bought the car used and it did not come with pinion gear. Just kind of want to have a reasonable pinion gear to start up. Probably it's a better idea to buy from local track.

Again, Thank you very much. I will be looking for guys that run the best on the track. Will be an interesting experience to learn!

Thanks man. I appreciate it!

Took some video onboard my B5m this past weekend at Stateline RC and thought I'd share it here. This was Q3 of the handout stock buggy class.

Nice. Love the overhead view coupled with the onboard view.

Adjusting the link length wise at the hub does not affect roll center very much. Adjusting it up and down does, certainly.

Adjusting the link length or height at the inside brace affects both significantly. This is why I advocate changing length at the hub if you only want to change camber rise as it has very little affect on roll center.

I can explain why this is the case if you disagree after my clarification.

That was awesome, front row view of the punts, baby head rocks on that track with the bonus of the over-view video for perspective. Curious what you used for the over-head view? Another person videoing or did you use that tracking gadget with the on board transponder?

You have this totally backwards. Adjusting the link height is a less drastic change than the link length. By making the link longer you are reducing its angle which lowers the roll center. The upper link is basically an upper arm like a real car would have. All of the the new AE manuals actually address this by saying:

"Changing the length of the camber link is considered a bigger step than adjusting
the ball end height on the rear chassis brace. Shortening the camber link
(or lowering the ball end) will give the rear end less roll and the car will tend to
accelerate or “square up” better. Lengthening the camber link (or raising the ball
end) will give the rear more roll and more cornering grip. Longer camber links are
typically used on high grip tracks, while shorter links tend to work better on
medium grip loose tracks. The kit setting is the best compromise of cornering grip
and acceleration.


AE keeps it basic and doesn't really address this as roll center but that's what they are talking about.

Over head view was recorded with a gopro clipped to my hat. Had to make sure I turned my head to watch my car and didn't just follow it with my eyes. lol
