It's a base setup and isn't designed to solve all issues. Different people will like suttle changes on the same track. I don't even use that setup in its entirety.
This leads me to my latest findings. I've been running on a lot of larger and rougher tracks lately and have some changes to the original setup that will help you get on the right track for rough, fast and loose conditions.
I'll include the original unchanged settings so you won't have to go back and forth.
Refer to your manual and the website for what each setting is as they have a lot of great info that's already out there.
SLASH 4x4 setup: FRONT END (for rough, loose and larger tracks - also works well with hotter motors and batteries)
- Toe: 1.5 (out), Flat side 'UP'
- Static Camber: -2.0, set at ride height and measure each wheel
independently with the wheel pointing straight forward.
- Camber Link: inner: #1 & outer: lower, This corrects the camber rise
to maintain a level of negative camber when fully extended. It makes
the front end (steering & control) more consistent & predictable
throughout the suspension range. Use the #2 position for even MORE
steering.
- Shock Position: Upper: mid/ Lower: #2
- Shock Length: 95mm, Increase the length by threading the rod end out
to expose a couple of threads. Increase in down travel improves
steering and helps settle the front end during landings.
- Shock springs: Slash 2wd fronts or Rustler RED fronts. Should be the
same as the newer white fronts on Rustler. These springs are softer
than the stockers and feel pretty good. The Rustler springs are a
linear rate and feel a bit smoother.
- Shock oil/ pistons: 50wt/ 2-hole, This is good for 60F to 80F - then go to 55wt
- Ride Height: Approx 29mm (shafts level), This will
also be affected by tire dia. My setup is with Pro-Line SC Calibers
and measured from surface to the skid just below the front of the
inner hinge pin.
- Sway Bar: silver (6mm in front of hollow ball)
- Diff: 7K (10K for hotter motors/ batteries)
- Bumpsteer: Flat: up
- Front hub carrier steering link: rear position (requires plastic [RTR] steering hub carriers), reduces steering, works well with plastic 2.5deg rear hub carriers.
Front end note: The plastic steering knuckles have two options for the steering link. Use the front hole for more steering. This will be the same as the Platinum with the aluminum accessory knuckles. Use the rear holes for less steering.
The plastic knuckles are acually nice to have on the truck. The rear
adjustment hole is good on large high bite tracks to keep turn
in smooth and less aggressive.
-----------------------------
SLASH 4x4 setup: REAR END (for rough, loose and larger tracks - also works well with hotter motors and batteries)
- Toe: 2.5deg plastic carriers, The 2.5's work well with the rear steering link hole on the plastic carriers. Helps track straight in the rough too.
- Static Camber: -3.0, set at ride height.
- Camber Link: inner: #3 & outer: fixed on plastic carriers and #3 on Pro-
Line rear carriers. Use the #5 hole on the inner on small high bite
tracks. It improves chassis rotation.
- Hinge Pin Location: Lower, Try the upper location on really rough
tracks. Reset ride height when changing this adjustment.
- Shock Position: Upper: mid Lower: #3
- Shock Length: 110mm, Increase the length by threading the rod end
out to expose a couple of threads. Increase in down travel improves
steering and helps the chassis settle during landings. Very handy on
those tracks that don't provide adequate landing jumps.
- Shocks Springs: T-Maxx White Progressives. These springs offer a
firmer feel and are longer and require less preload, which allows them
to work within a happy range.
- Shock oil/ pistons: 45wt/ 2-hole, This is good for 60F to 80F, try 50wt after that.
- Ride Height: Approx 31mm (shafts slightly above level), This will
also be affected by tire dia. My setup is with Pro-Line SC Calibers
and measured from surface to the bott the skid just below the rear of
the inner hinge pin. Lower this setting to level with the front on
high speed smooth tracks.
- Sway Bar: Siver (2mm sticking out from hollow ball),
- Diff: 5K, Try 3K on really loose and dusty tracks
---------------------------------
SLASH 4x4 setup: The REST
Wheels: Pro-Line SC One Piece (Slash 2wd rear offset) all the way
around
Inserts: Pro-Line SC Blue
Tires: Pro-Line SC Calibers, Bowties & Switches, Calibers have been
good on most everything and consistent between bite and loose. Bowties
favor loose and offer better forward bite vs. site bite. Good for
chassis rotation and acceleration. The Switches are good on really
hite tracks and abrasive surfaces. M3 is good in colder weather and
also in dusty situations. M2 works well in warmer temps and on
abrasive clean surfaces.
Motor: TRX Velineon (with TRX heatsink #1522), Castle 4600kv and 5700kv motors are great for Open modified class racing, The mamba Monster ESC with the larger 2650kv motor is powerful and smooth and barely gets warm.
Battery: Thunder Power 2S 7.4v 5200. The 25C and 40C are great all-around packs with the 50C packs offering more punch for faster motors.
Battery Location: rear
ESC: TRX Velineon VXL-3s (with cooling fan), Castle Mamba Max Pro and Monster ESC's are great for the hotter motors and offer some pretty cool tuning features.
Gearing:
TRX VXL - Pinion: 14t thru 16t (depending on track size)/ Spur: 54t, use 13t pinion on tight tracks. If running 3S packs, gear down to 12t pinion.
Castle 4300/ 5700 - Pinion: 12t thru 14t (depending on track size)/ Spur: 54t, use 11t and 12t pinions on higher kv motors.
Castle 2200/ 2650 - Pinion: 17t thru 22t (depending on track size)/ Spur: 50t thru 54t, use larger pinions and smaller spurs on the 2200kv motor.
Starting setup for 2650kv motor: 18/52
Starting setup for 2200kv motor: 22/52
Note: Larger pinions also improves control of the truck in the air. Something to think about on jumps that buck the rear or high speed jumps that need a little extra to keep the front level.
Center Diff: 50K, Try lighter mixes of 50K and 100K to get softer
acceleration and better turn in.
TX: Spektrum DX3R
RX: Spektrum SR 3100
Servo: Ace 1015
Body: Pro-Line SC Hardcore
The Thunder Power packs are 5200mah and are lighter than the previously posted 8000mah packs. The truck is working great and is handling well with the lighter weight pack. The Thunder Power packs are hard cased and ROAR legal too. Very punchy.
Try some of these things and see how they work for you.
