So its been a while since Casper and I got to spend a satruday at the track together and decided to just wrench on the 22-sct's today. Overall, we both started off very happy with our SCT's but we finished up incredibly excited by our 22SCT's, dropped about 1.0-1.3 seconds off our fast lap and brought the average down by about the same...so very significant and way easy to drive. Feel free to try it out and comment back...

Here it is...

Front

2 hole 1.5/27.5wt losi oil
shock mounted middle on top and outside on bottom.
Shock had NO limiters in it and was unscrewed 3 turns.
We ended up with green truck front springs but if you want a little more push, you can use the blue truck front springs.
Camber link on inside with 3mm, spindles centered.
No bumpsteer washers, 2 old gold washers under the rack side ball stud for the ling from the servo to the rack.
Ride height at 26.5mm measured with AE ride height guage.
White sway bar. 30/0.
1 deg neg camber, 1 toe in.

Rear

2 hole 1.6/30wt losi oil, shock mounted 3 on top and outside on bottom with NO limiters and shock unscrewed 1 turn.
Yellow buggy rear springs.
Camber link 1-B with 2mm under both, hubs forward all the way.
Ride height at 26.5mm.
White sway bar.
2 deg anti squat, 3 deg toe LRC.
2 deg neg camber.

The only weight in the car now is 2 TLR weights over the tranny so 14 grams. The battery is a long pack, one older CR pad behind the battery only with the stop moved back to keep it from sliding forward. This gives great forward traction which has been a bit limited on this car until now.

The limiters being removed is huge so please dont get lazy here, lol. Dual rate turned down to between 93-95%


Ryan



The original setup I posted was good and easy to drive. I knew it was missing forward bite (we run mod, Ryan 6.5 Tekin GenII and myself 8.5 Tekin GenII to answer one of the questions above). The car was so easy to drive and lap times were very competative with the other fast guys at the track so I posted it up. As Ryan said it has been a while since we spent a day working on setups so it was great fun and very productive. (this is how we came up with the great SCTE setups by the way!). We combined some of the things the team had been working on and what we felt was already good and we came up with something we think is GREAT. The layout at OCRC has been in for over a month. Ryan ran (and won!) a 4 week series at this track with the old setup so he was not slow (won all 4 rounds!) Yesterday in practice with no ideal track conditions and lots of traffic we were dropping average times by 1 sec. The insane thing was we knew we were not running "clean" laps as we were dogging traffic and just making those small mistakes in trying to get those ringer laps and we were still going faster. Truck has a significant more forward bite and is even more stable and easier to drive.

Also we are using 22 +1.5 hexes up front. Std SCT hexes in the rear.

Casper

Ryan - with this setup the main things I note are different from the last setup Caper posted are:

Ride height down to 26mm from 29/30
Shock limiters out and shafts lengthened
Washers on the steering rack link from servo
Weight and battery position changes

What do you feel are the effects of increased droop?

What are the effects of the washers under that ball stud on the steering rack servo linkage?

The truck is much more predictable, it is just plain easier to drive and thus you can finally push the truck nice and hard. The car turns in good, through good, and out good, and has rear traction. The washers under the servo ball stud on teh rack change the expo in a way. They make it more linear rather than as aggressive off center.


Ryan or Casper, how do you think this new found setup will apply to us stock racers? I know that we will not be running as much or in my case any weight in the truck. I like to run a shorty pack in the truck.

I think this setup for stock racers as it uses very little weight and you will get a lot of forward traction would be very good. If you are running the shorty pack, you will want to play with placement in the range we were running the larger pack.


Ryan, what are your tire combos?
Less aggressive up front?
I couldn't run equal tires front and rear no matter what I tried so I settled on less aggressive fronts.
I'm now running AKA Wishbones front and Gold Barcodes or Suburbs rear to get a comfortable balance.

I run panther rattlers front and rear. I sometimes run a bit harder front clay versus the rear clay but usually of the same tread. When I run outdoors, I usually run one harder front versus rear.


Is that TLR2932?

Yes


I have NIP set of .75 22 hexes. Can I use those in place of the 1.5's? I have no use for them so.......

Those would be more narrow then stock SCT front hexes and even though they will "fit" not the direction you want to go. Stock would be better. The 22 +1.5's are just slightly wider then stock.


I still don't understand the difference between caster/kick 25/5 and 30/0. Overall it's 30 bu there's a difference?

Did you read this? Team Losi Racing 22 & 22T - Adjusting kick


The 1.5 2 hole are those associated ?

We are drilling TLR pistons but AE's fit as well.


Ryan and Casper, thanks for the new setup. Now think you guys could come up with a new one for 22 buggy to get it to not push as bad?

It will be a couple weeks before we get a chance to do this again with the holidays but I think we will tackle the 22T next (it is close but can get better and then we will hit up the 22 again. Both of use like our 22 right now even though we each have a different setup. Is it pushing high speed or low speed and what tires are you running.
