Upper track Rods
Front:
In the stock position (5/Out) the front upper track rods are in “neutral” position allowing the
shocks to control the movement of the axle. Raising the track rods will stiffen the front causing less chas-
sis roll. Lowering the track rods will cause more chassis roll and allow the front axle to react to obstacles
easier. Raising the front track rods will increase the front traction, but make it more difficult for the suspen
-
sion to react to obstacles.
Rear:
In the stock position (5/Out) the rear upper track rods are in a “neutral” position. Raising the
rear track rods will make the rear more stable, but less reactive to obstacles. Lowering the rear track rods
will create more traction, but will also allow more “sway” and make the rear feel less stable. In testing we
have found that lowering the rear track rods will increase rear bite. However, on some vertical climbs, too
much rear bite can cause the front end to lift and lose traction.
Shocks
The Mini Rock Crawler Pro has 3 upper shock mounting positions. The kit is set with the shocks in the
middle (2) position. Running the shocks in the outer-most position (3) will increase spring rate and chas-
sis body roll. Mounting the shocks in the inner-most position (1) will decrease spring rate and allow the
suspension to react more slowly to obstacles.
Shock Arm Position:
Raised Shock Arm:
Raising the shock arms (A) will lower the chassis and center of gravity, making the
crawler more stable for smooth climbs, descents, and side-hills. This position works best for areas with
smooth rocks and steep vertical climbs (slickrock, granite, etc.)
Lowered Shock Arm:
Lowering the shock arms (B) will raise the chassis and provide more ground
clearance. This position works best for areas with loose or jagged rocks (river beds, volcanic rocks, etc.).
Motor/Battery Combo Suggestions:
The Mini Rock Crawler Pro is designed to use the stock Mini-Rock Crawler ESC (LOSB0828) and motor
(LOSB0839). For more power and torque, we suggest using the Xcelorin™ 1/18th Sensored ESC/Motor
Combo (LOSB9567) with a 2S LiPo battery (LOSB9831).
Team Tips
Wheel Weights:
By installing LOSA99201 “Self-stick Chassis Weights” inside the wheels, on the internal wheel ring, overall
traction can be improved. Our Team drivers have found that adding 3 ounces to each front wheel and 1.5
to each rear wheel is a great start. Depending on your terrain you may want to increase or decrease the
weight.
Shock Tuning:
The kit setup includes 30-weightoil with 5mm limiters inside the shocks. Our Team Drivers found that run-
ning stiffer oil and more pre-load on the right rear shock helps further dampen the effects of “torque twist”.
In addition, use of the LOSB1446 Outboard Shock Spacer Kit is highly recommended to increase side
hilling stability.
They have also found that running a softer spring and lighter oil in both front shocks allows the front to
react to obstacles easier and flow over the rocks with greater control.
Weight Bias:
By flipping the transmission and skid plate 180° you are able to shift the weight of the motor slightly
forward, increasing the forward weight bias. This is very helpful in areas with break-overs or steep vertical
climbs. You will have to reverse the rotation of the motor with this modification.
Suspension Geometry:
The Mini Rock Crawler Pro suspension geometry is designed to minimize axle steer and the effects of
torque twist. However, these effects can never be completely eliminated. Through extensive testing, our
Team Drivers have determined that using more preload, firmer springs, and stiffer oil in the rear shocks
can help dampen the effects of torque twist. Lowering the rear track rods creates more anti-squat which
can counteract torque twist in some situations.
