Thanks! I found the pace for the last finals but I think there is a lot more to test out, especially with the RRS.

A picture tells a thousand words. Outside hole on the steering knuckle. Going over the car tonight I thought about dropping the shims from under the toe blocks and I've moved to 2mm shim under the knuckle and 0 on the RRS link. I'm keen to see if there is any change with the same setting just different link heights. If one of you guys could post a similar picture of your car we could compare link and knuckle angles.

Finally got some track time last night first time driving my new 411 and I have to say that I'm amazed. Love it.

Threads gone quiet. A good sign ppls cars are working well.


Ok I've done a heap more testing with the RRS and the car how I have it set now is amazing. I still want to play with the rear wheel base again and see how it feels. I'd like to run the old style 2 hole arms in the front and see if i can get the front end even nicer running the outside shock position. I always felt that was nicer on the old version. Other than that I feel if I can just concentrate on driving cleaner lines I'll be able to crack 28 laps. Old electrics I feel is holding me back on the hot lap as my HW13.5 is thrashed after 5 months service. I need a new motor to crack the magical 12.99 at my track. I've got a new D4 in and R1wurks motor coming to test out next practice so fingers crossed. The local fast kid is doing 12.7 so the track definitely has it in it.

I'm still getting used to driving lines differently but the car is super consistent albeit a little slow compared to the others I'm racing. My best time previously was 27/6.07 and I got down to a 27/6.01 with a 13.1 hot lap last meet. At the end of the last final I had a 10 lap battle I won against the local 13yo hot shot. We run anti clockwise and have a large left hand sweeper that you take at full speed if possible. I can hold the tightest line and pull the car up straight every lap so it was impossible to get the inside line on me. I was getting hassled in the straights so I know it's a HP issue as the twisty stuff it's unbelievable.

As for the RRS I found going under minus 2 degree static toe pointless. The car missed that initial bite at corner entry with less than 2. I found a happy balance with -2.5 at static and just over -4 at full compression. I ended up running the 0/2.5 blocks but id like to go back to the kit 0.5/3.5 and wind it back at the hubs. I want to also test a longer wheel base as I'm currently running a short rear compared to my normal set up. I see from some of the recent set up sheets posted guys are running a different front end set up so I'll give that a crack too. I'll post a set up sheet shortly.

A few random notes. I don't think I'll be using the std speed 6 anymore. The GX works very well but the LTCR is it for overall pace. I won't be running grey rear anymore. I feel the angle change with black springs all round is faster as the grip changes. Green front produces a much more stable car to race in finals and I will test this next meet from the start as it may produce faster times overall. I really feel like I won't use all the Hpi and ride springs I have as the serpent springs work so good. If like to see a spring released between black and green. The new gear diff gears are the hot ticket. I've replaced all the internals on my old diffs and I now have 4 Diff built with 3/4/5/6k oils for the grip changes thru the night. I'm almost contemplating the diff change before the shock change as the grip rises.

Lastly id like to share my latest hot run. The 2nd fasted lap for this run was the final lap.
Love this car.

Great to hear that the RRS is working for you! I havenīt found a good setup for carpet yet. I struggled with the RRS last practice, ended up taking it out and put on a close to standard box setup with great results. Sometimes itīs good to get back to basics and not look too much at other peoples setup. I would urge people to test the shocks with VBC o-rings. Though a little leaky (adding a little oil after 10 packs) the shocks feel extremely good and precise adding more grip and response. I also have raised the upper deck 0.5 mm for a little more flex.

Part number? I'm using the Kyosho xrings. I have some of the rsd orings coming in as a lot of racers are using them here. They handle the track heat we get during summer. . I've found using the Tamiya small shim kit with around 0.2-0.4 of shim stopping all the leaking. I'm using the Tamiya or the older style serpent bladders as I'm finding with the new low profile ones the shock collars hard to adjust as the shock spins on the bladder instead of biting in.

I got the 411's out a bit over the weekend. My S411 is a hybrid now, started life as an LE but now had the Eryx 3.0 shocks, DCJ's, steering, chassis, motor mount, and hinge pin blocks. I am running the LE top deck (stock 411, TE, LE) and the center chassis brace.

RRS with 2*, outer hole, 1mm spacer, 2.5 static, the car was over-rotating. I am running Serpent white all around, 1mil front diff, 5k rear (V1 diff with 2 gear). Traction is high, and the setup is from rediculously high and not ideal tires. Back with Jaco Blues, I think I can go back to the front spool and stiffen the car up. The transition side to side is very slow, which is only an issue currently in the chicane. The rear also gets loose after 4-5 min, which I think is from too much steering. Will work on it some more, but I think the RRS should allow for better corner speeds once the setup is matched to it.

Somewhat wrong thread, but I was racing my USGT car (S411FF) and having some decent luck with it. I still am suffering from corner exit speed, but anything I do with more torque (gearing or can timing) just leads to wheel spin. I am also traction rolling in 2 spots but have some spring changes to try. Car is very interesting though, and drives completely different. It does not drive at all how I would expect though. The rear end is locked in, it steers incredible, and is very consistent. I just can't accelerate full through the sweepers without it rolling.

Unfortunately another month out from the next onroad testing, but will reply back then with how the new changes to the RRS car are working.

Default WCIC Race #3

So I had some pretty decent luck on the weekend in Stock TC, Mod not so much, but that one is a learning curve for me.

http://www.petitrc.com/reglages/serp...141123/​

(I would include the link to this on the Serpent site, but I'm blocked with the current computer I work on.If someone could add that for me, it would be appreciated.)

I'll explain some of the setup points. First off I messed up on the setup sheet for the camber settings, I blame the RRS for this, as eventually I don't know which end of the car I'm looking at, lol.

We where on Sweep QTS32 tires and using SXT 3.0 traction compound. For the last 2 runs I was full rear sauce and only 3/4 of the inside of the front tire. Take note, if your running on a track with tape that is on the race line, the 3/4 or 1/2 sauce on the front allows you to hit the tape without the violent grip roll issue that can sometimes happen.

I found the same issue with the RRS system causing a touch oversteer on exit especially as the traction came up on the track. But wait, don't throw the system away, as I found that leaving the lower mount in stiffened the rear up a little and help make the car feel locked in at the back, especially with the 3.0 where we don't have the 3rd screw option in the top deck anymore.

If your diff is on the clear/white o-rings you may have to run lighter diff oil, I hear the black rings are better, but did not get a chance to try them. If your running a thicker oil with the old rings every once in a while the diff doesn't diff smoothly, usually mid corner and will give a strange oversteer on exit feel to the car.

The 2.0 top deck is NOT the flexi deck but the older full deck, this has really settled the car down for us on carpet. I tried the 1.75 and the 2.50 decks as well, but the 2.0 has netted the best results. The 1.75 feels better in the mod car and the 2.50 deck seems to be working well in the CTA/VTA cars.

Played around with the front steering blocks, running them in the normal position and in the flipped position and found that in normal the cars front end feels neutral, and in the flipped position it gives a slightly more aggressive feel to the steering.

I have been running the Traxxas blue xrings in my lower shocks, along with the Yokomo shims (0.2,0.3,0.5 set) which allows me to adjust the compression on the outer portion of the xring, this control the feel and the leakage quite nicely. I actually found one of my shocks need a slightly different amount of shims to get it to feel like the other shock. Not sure if its a machining issue with the shock body or a slightly different xring, but they both feel the same now.

Speaking of shocks, I also ended up running drilled caps in the front of the car. But in the rear I left them stock and had a small amount of rebound, which made the car react better in the tight sections of the track.

If you guys have any questions feel free to ask.

Thanks

Imdoor Champs starting tomorrow..... Myself, Adam Russell, Chicky, and Mr. Wise will be there representing in all TC classes. Anyone else going?!?

Hopefully my car is still as good as it was at the Halloween Classic!

I have been running the Traxxas blue xrings in my lower shocks, along with the Yokomo shims (0.2,0.3,0.5 set) which allows me to adjust the compression on the outer portion of the xring, this control the feel and the leakage quite nicely. I actually found one of my shocks need a slightly different amount of shims to get it to feel like the other shock. Not sure if its a machining issue with the shock body or a slightly different xring, but they both feel the same now.

Speaking of shocks, I also ended up running drilled caps in the front of the car. But in the rear I left them stock and had a small amount of rebound, which made the car react better in the tight sections of the track.

If you guys have any questions feel free to ask.

Thanks
Gary forgot to mention he tqed stock! Nice job Gary! Here is the link to his report. http://teamserpent.com/blog/category/onroad/

If anyone have setup tips with LRP CPX tires I would love to hear them. The tires have by default low side grip so the setup need to generate a lot of mechanical grip. With Ride tires the car feels great.
