Default Best Weight for 17.5 Stock Buggy

Tried running the buggy at approx 1500g but handled better at 1550. Weight diff was lighter battery. Set ride height per each battery weight. Would be interesting to hear what other 17.5 stock buggy drivers are weighed at.

I have tried weight focused testing over several generations of buggies. There is always a compromise between a single super fast lap and driveability. My over all time and best average lap are always with a car 3-5 ounces over minimum weight. My best single lap time is always with an edgier feeling car that was at the lightest weight.

This is with shock spring and valving adjusted for weight changes and balance almost entirely unchanged.

There could be other factors, like tire insert changes to suit each weight as well, but I preferred to keep as much the same as possible.




The major grey area, imo, is a lighter car might like different roll centers and camber link lengths(RCM), since it would transfer less weight.
Lots of variables.

Biggest thing, I found, not hitting stuff.

I run mine "up" position middle hole with no washers. If you like to mess with roll center a bunch run it down with two spacers. It is easier to add/remove spacers than to flip the mount.

To anyone with the Xfactory Chassis, I have the aluminum rear a-arm mounts and it doesn't sit flush inside the chassis... Has anyone come across this? I noticed this when I went to tighten the mount into the chassis and saw it flexing.

Ran the inline battery setup today and all i can say is wow... Didnt feel like a dog in mid and exit cornering anymore!! Rotates so quick. Knocked .5 second off my laptimes!! Buggy was unbelievably so easy to drive!! It fealt so much more better jumping also... Could tailwhip so easy and readjust mid air if you launched off position. What an unbelievable change of heart cause I kept on switching back to the rear motor car. So glad i stayed with it and found this setup!!! Thank you guys!!

I don't have the chassis, but I follow the company and IIRC the first batch or two didn't have enough material removed for certain rear a-arm mounts. You should contact them and I'm sure they'll help you get this figured out.

My setup from testing and tuning today. After moving to the shorty, my car felt great, but it was "too stood up" and rotated way too much in corners. It also lacked traction in general. After going to green rear springs for our track that can get pretty slippery, I played with the front and determined I really needed to go back to the gray springs as it was just not stable enough with the whites I as running previously from outdoor racing. That got it better, but it still felt like it had inconsistent rotation. It wasn't a traction thing, it was rotation under braking was not like it should be. I started playing with rear droop and went from 26.5 to 27.5 and that was the ticket.

I ran that setup with 1.5 fronts and 1.6 rears. White rear springs with grey front springs also...absolutely glued.

So I just picked up the Schelle Nova Slipper! I've noticed a lot of comments about stock pad set-up, but what are you guys running for mod?
I run on carpet and high grip clay- so would white-red-red be good? Or would it put down too much power from my 7.5?

The Lunsford screws are grade 5 made in the usa with ti made in the usa, others are grade 2. I would prefer a grade 5 over grade 2 any day!
