I purchased a the 2mm soft chassis (Mingnon Walter RC has stock of these) to use at a low traction track and one piece motor mount just waiting on the local supplier to get the flex top deck in and i will get one of these as well. I ran the LE in std config 2 weeks ago and struggled big time for grip so hopefully this will help. I also removed the servo holders and taped the servo so as not to loose flex through the front of the chassis also went to a softer shock oil as well as orange springs all round.

The box setup and parts in the LE work great on a gripped up track just struggled with a low grip track first time out.

I guess i will see what happens on Friday night

Well I ran the 2.0 and flex top deck today for the first time. Unfortunately we got snowed out before the second heat. I really liked what I felt for the short time I ran, I practiced a lot, much more than usual. The setup was strong on rear grip for the first time since I have ran the car. I am just not sure how much the ball diff had to do with it, I tightened the diff down pretty tight and still had great rear end grip. I am definetely the closest I have been for low traction asphalt.
This weeks changes pre race were v2 rack, chassis top deck and ball diff.
I actually tried droop settings and ride height settings to get more forward bite as the above changes gave me a mild push from apex out.

I find that even on carpet that if I'm struggling to get the right thickness of fluid in the gear diff, I will run a ball diff.......it sort of gives me a feel that perhaps my setup is okay but my gear diff is off, no use chasing setup if its good but the diff is making the car act loose. After thats sorted I'll figure out if the diff needs thicker or thinner fluid and go from there.

If I remember correctly, way back in this thread, someone actually narrowed the rear section of the chassis, cutting it in a bit to get even more rear traction. I don't remember if it was pre 2.0 chassis or post, though. I think the waist was reduced to about the same distance as the front of the car is done in stock form.

Post you're setup if you can, and we can see if we can help you out. Just curious about the orange springs though, are you on asphalt or carpet? The stock setup isn't the best in some cases.

Just my opinion and there are others that are more infomed, you have very heavy oil in your rear shocks also the springs could be softer try the yellow rear with the orange up front. The higher ride height in rear plays into this also making weight transfer to the rear end for traction not easy. I would run the same or lower cst shock oil in rear, softer springs and lower rear ride height.
I also run 4-5 mm spacing in front of rear arms.
hope that helps

Hey Mike.

I agree with rdlkgliders... way to stiff...make ride height the same etc. Also the front roll center is too low at ony 3mm spacers on inboard upper arm. Also the front shock oil is too light for the springs you are running, an the rear shock oil is waaaayyy too stiff.

Can I make a suggestion.. I would start with my setup listed here
http://serpent.com/file.php?FileID=5367

,,,and just play with spring rates I think the white will be a good spring rate for a low grip asphalt, but you may want to try a gray,..but nothing harder.

If you want more rear grip you can a) use the 3.5 rear toe in block b) use 3mm instead of 4mm on inboard upper link. I would try (b) before (a) to reduce the chances of the rear tires overheating later in the run due to too much slip angle.

You may also want to checkout my setup app available for android and for apple devices at www.setupworkbench.com, to help you learn more about how to setup your car so you can enjoy that serpent more!

good stuff. that setup should give you lots of steering for sure.

Do you prep the concrete at all ? That has to be a pretty slippery surface. I wonder if the car is far to aggressive in the front end. Maybe changing the castor and eliminate the arm sweep, just throwing that out there as I have had no experience on concrete.

I have been running white, yellow or grey, black rear and front spring combo's on asphalt with good results.
The app setup workbench works awsome great tool.
I wish I could print the cheat sheet page for easy access and old eyes.
