[restimax]

i'm a little disappoint, i can not found a good setup for my track

this is the track:



i use the same tyres of other drivers.
esc xerun 120 2.1
lipo stick
motor feigao 6.5 with 17 pinion.
this is my last setup:
front:
oil losi 35 1 hole no valve internal spacer 4mm.
spring 5.5
Caster min, upper front amrs all front, next time i try with: max caster 21° with mod
pushrod short, (next time try with standard pushrod)
camber 1°
toe 0°

rear:
oil 35 losi 1 hole no valve
spring 6 + pre compression gold
max drop
shock on lower hole
upright on higher hole (next time i try with lower hole)

Try softer rear oil - 30wt with softer springs and run more toe in on the rear.

What camber are you running on the back?

rear camber 1°
i have used oil 30 but is to low with this temperature (the track is indoor and the temperature is over 30°C very hot...) when the car landing, the rear touch the ground very strong.

Ps:
the pred.co is off line from some days...

You can also try to loosen the slipper a little bit (let's say 1/16 of a turn) to make the car less agressive during acceleration.

I'm having my first race on clay surface with the pred this weekend so I'm also a bit excited and having a lot of questions in terms of setup

good luck for your race!
in my experience, the clutch of the pred is not much stable and reliable

If it has power-on oversteer, try less steering lock.

Hey Maxi

Having a quick look at your set up, maybe you could try using a 23 tooth pinion with the motor that you are using. This should make it accelerate smoother.

Hope that helps

[Mrs.TeamXtreme]

Also you could try front rebound valves and blue rear springs on the middle hole on rocker.

no, because, in some tight turns the car is in understeer

Thanks, but just with the 19 tooth pinion the motor is very hot and after few minutes the speedo is in protection...

Hello, I was running a Novak 6.5 on an 18t pinion, the motor got so hot it had meltdown! now i run a 6.5 on 23t pinion and it runs much cooler and much less aggressive to drive!
The last time I ran on Astro I had the following setup.
Front shocks
losi 30wt oil
2 hole piston
yellow spring
No rebound valve or limiters

Rear shocks
35wt losi oil
2 hole piston
Red spring with pre-compression spring
No limiters or rebound valves

Max caster
1 deg camber front 3 deg on the rear
Max droop
Middle hole on rear shock towers
Front ride height 19mm
Rear ride height 21mm (wishbone just below level)
Rear sway bar on soft setting
Top hole in rear hubs

Worth a try!

Also worth possibly keeping an eye on www.teamnoidea.com as soon as this UK weather gets better ill be out testing every 5 mins and reporting about setups on the site.

[restimax]

thanks for the tips of the pinion i will try asap.
I'm sorry but it is not astro, the first image has the colors distorted by the camera, but it is hard clay ground.

[Stretch]

Maybe reducing the punch on the speedo would help too...

[restimax]

thanks to all guys,

today i have worked a lot on the setting, i think is only a problem of balance...
because with the front soft and without the spacer (my new setup of today), with more drop and a soft oil the car have a good grip at front and rear.... with the spacer and the oil stronger the front have a little roll and the rear the same, in fact in the corner entry, the car was understeering and oversteering in the out, but now is much more balanced.

my problem now is found a good ratio, because with 23 tooth pinion the esc is in protection.... same with 22,19, and 17 th pinion....

this is my new setup:
front:
1 hole
oil losi 30
no valve
spring 5.5
max caster 21°
standard pushrod
camber 1°
toe 0°

rear
1 hole
oil 35
no valve
spring 6.5
upright lower hole
wheelbase lenghtened of 2mm.
upright with camber joint mod.
big wing team azarashi with max gurney
camber 2°
toe in 3,5°

and same other bits tomorrow....

[restimax]

this is my last mod make the rear more driveable.... tha camber link now is 8mm more long. and work always parallel to the lower wishbones.

i think is better, this is a copy of the upright modded for the euro 08 in Italy from Nathan Ralls. the car is more easy to drive in a slippery track, in the in and out of turns.

you need a new turnbuckle 4mm 28-30 mm longher.

Thanks!

Now where is my Dremel?!
