Taking the S411 (and the S120) to the USVTA Southern Nationals this weekend. Car has felt very good lately, but still a good bit off pace (0.6 sec a lap at home track fast lap to fast lap) and 0.8-0.9 off on regular lapping. I have not had the practice lately which is a big part of it as well.
As I haven't been following this thread as consistently as I was able to in the past, I am curious what the theory is now on the motor mount. It seems the hybrid V1/V2 seems like the new thing to try? Full top deck screws or still skipping some of those near the motor mount?
Current track is a bit bumpy, but the one this weekend is glass smooth. I am assuming I can stiffen things up a little and go for some more traction bite to power through corners a little more aggressively then? Thinking things like sways, shock oil and springs primarily, as I do not have the chassis and top deck options (just stock and flex top decks, and my chassis's are 2.25).
When you guys go to a new track (layout or venue) do you take the car back to either box stock, or some other version of setup, and tune from there? Or do you take what you have, and then adjust as the conditions warrant?

If you plan to go on a higher bite track, expect to take out uptravel, raise camber links, and maybe soften the springs depending how you usually run them. If going to lower bite, do what is necessary to get the back end stuck first, like increase toe, thinner diff oil, lower roll center, etc. I can't tell you how many people would break out of a race from getting loose in the sweeper and causing accidents.
The car doesn't need to be as fast as the track allows..... only faster than the others!

Went from a front gear diff and rear steel shafts to the nylon spool (with sleeves) and aluminun shafts. It cut about 21g of rotating mass from the car, which is a LOT. The gear diffs are heavy so no surprise there, but even the steel spool is about 18, compared to 8-9 for the nylon.

Anyone ever noticed their rear toe being asymmetrical? One side is 3 deg as expected and the other is closer to 2. I don't know if the problem is in the brackets, uprights, or arms.

DJC driveshafts?
Anyone know when the "Serpent DJC Driveshaft Set (2)
[SER401445]" will be back in stock in the US? I saw that amain and stormer hobbies are out of stock.
Any other US distributors have these upgraded driveshafts? Thanks for the help

just thought I'd share some pics of some parts I'm gonna test out this weekend...
Top deck is a standard 2mm carbon, cut to the same shape as flexie version, but with a more forward flex point, similar in position to other cars out there (i.e. above the steering posts!)
Second pic is my prototype centre servo mount. It's a bit rough round the edges, and a bit too thick in places (even though it's only 5-6g)... can be better! Gonna need to drill an extra hole in the chassis too!
Excuse the crappy iPhone pics though!

I normally find a good baseline setup and start at that each track.... it may be the kit setup, or it may be waaay out there... as long as it is comfortable to you!

Excited to get back to the track and work on some of the new things everyone here is doing and try and get a little more corner speed out of the car.

Can I ask what you servo mount start life as or have you made it from scratch?
