Please note the following precautions before running
your 1/10 HIGHroller.
• The Electronics in this vehicle are not waterproof and you
must avoid running the vehicle in or through standing
water, wet grass, mud or snow.
• This vehicle is quick:
o Do not run the vehicle if it will be out of sight for any
amount of time.
o Do not drive your vehicle near a crowd of people.
• Perform a check of the vehicle before going out to run it.
o Ensure the tires are not coming off the rims.
o Generally check the vehicle for items such as a
loose wheel nut, or anything loose on the steering
assembly. The vibrations of running off-road tend to
loosen screws and nuts.
• Be careful driving when the battery is nearly discharged or
the car is running slowly. You could lose enough power for
the receiver to shutdown and you may lose control.
• When driving the 1/10 HIGHroller be cautious and use
common sense.
• If your vehicle gets caught or stuck do not pull the throttle
in either forward or reverse. This will overload the ESC
and/or motor resulting in damage to one or possibly both
and is not covered by your warranty.
• After running a battery pack, allow the electronics several
minutes to cool before running the next battery pack.
Run time consideration for the 1/10 HIGHroller vehicle.
The single largest factor in run time is the capacity mAh of
your battery pack. The larger the mAh rating the more run time
you will experience. On the same note, the longer you run, the
hotter the battery plugs can get. Please check the standard
plugs periodically.
For example: if you have a 4600mAh battery pack you can
expect close to twice the run time of a 2000mAh battery pack.
The condition of a battery pack is also an important factor in
both run time and speed. As batteries see more use they will
degrade in performance and capacity.
Driving the 1/10 HIGHroller How you drive your 1/10 HIGHroller will also affect your run
times. If you are performing runs, going from a standstill to full
speed repeatedly, you are asking a lot from your batteries and
electronics. Hard acceleration draws a lot of current from any
battery and will lead to shortened run time.
If the bearings are dirty they will cause significant drag causing
reduced run times and speed.
To improve run times consider the following:
• Keep your vehicle clean and maintained.
• Allow more airflow to the heat sink of the MSC 12RB ESC.
• Change the gearing to a lower ratio, this will make the
electronics run cooler. This can be accomplished by using
a smaller pinion gear than those originally supplied. (The
1/10 HIGHroller comes with a 12-tooth pinion and an
90-tooth spur gear.)
• Change to battery packs of higher mAh rating.
• Is the charger you’re using the best at charging your
batteries? Check with your local hobby dealer.
Tuning, Adjusting & Maintaining the
1/10 HIGHroller
Periodically examine your 1/10 HIGHroller for the
following:
• Keep your vehicle clean using a brush to remove dirt
and dust.
• Look for cracks in the suspension arms and other
molded parts.
• Check that the tires are still glued to the wheels.
• Check that all the wheel bearings are clean and lubricated.
• Using your tools, attempt to tighten all the screws and
nuts.
• Verify that the camber links and steering linkage are
not bent.
• Check that the toe and camber settings are as desired
and equal.
• Remove the gear cover.
o Check the spur gear for wear.
o Check the pinion gear.
o Check the slipper pads for wear.
• Take the shocks off the vehicle and check, especially if they
appear to be leaking as it is time to rebuild them.
• Look over all the wiring and connections for bare wire or
any place which could lead to a short circuit.
• Verify that the ESC is securely mounted to the chassis.
• Verify the receiver is still securely mounted to the chassis.
• Turn on the radio. If the Green LED is off or dim, replace
the 8 AA batteries in the transmitter.
After you become familiar with driving your 1/10 HIGHroller,
you may need to reset or make adjustments for better
driving performance.
Just as in a real car, alignment is an important factor in your
vehicle’s handling. When you are ready to make adjustments
it is a good idea to have a flat work space to place your vehicle
on. This will enable you to easily and more quickly make both
toe-in and camber adjustments. These adjustments should be
set with the vehicle sitting at its normal ride height.
Tuning the Front End of the 1/10 HIGHroller
Shock Location: The 1/10 HIGHroller has three mounting
locations on the front shock tower. The position can be easily
adjusted by simply moving the top of the shock to another
hole. The standard location (middle hole on the tower) works
best on most surfaces. Moving the top of the shock inward a
hole will slow steering response and make the 1/10 HIGHroller
smoother in bumps. Running the inside shock location on the
arm will give the 1/10 HIGHroller more steering into the turn
and less steering on corner exit. Running the shock location
outside on the front arm will give you less overall steering
into the turn and keep the front end flatter through the turn,
making the 1/10 HIGHroller smoother and easier to drive. This
can be used on high-traction surfaces.
Using the supplied flat metal turnbuckle wrench if you need
to SHORTEN any link on the 1/10 HIGHroller, rotate the wrench
towards the rear of the vehicle (clockwise). If you need to
LENGTHEN any link then rotate the wrench towards the front of
the vehicle (counterclockwise).
Static Camber: This refers to the angle of the wheels/tires
relative to the surface (viewed from either the front or back).
Negative camber means that the top of the tire leans in toward
the chassis. Positive camber means the top of the tire leans out,
away from the chassis. Camber can be precisely measured with
aftermarket camber gauges, sold at local hobby shops. It can
be measured (roughly) using any square (to the ground) object
by checking the gap between the square edge and the top of
the tire. Testing has shown that 1 degree of negative camber
is best for most track conditions. Increasing negative camber
(in the range of 1-2 degrees) will generally increase steering.
Decreasing negative camber (in the range of 0-1 degree) will
generally decrease steering and the 1/10 HIGHroller will feel
easier to drive as a result. This is, most often, a very critical
adjustment in tuning your 1/10 HIGHroller that can be made
quickly and easily.
