Please note the following precautions before running
your Desert Truck.
• 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.
• The Desert Truck’s gearing choice from the factory IS NOT
meant for running the vehicle in tall grass.
• 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 Desert Truck 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 Desert Truck 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 Desert Truck
How you drive your Desert Truck 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, or a larger spur gear than those
originally supplied. (The Desert Truck comes with a 16-
tooth pinion and an 88-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.
