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 ESC.
»
Change the gearing to a lower ratio; this will make the
electronics run cooler. To change gear ratio, use a smaller
pinion gear or a larger spur gear than those originally
supplied (the Twin Hammers vehicle comes with
a 28-tooth pinion and a 78-tooth spur gear).
»
Change to battery packs of higher mAh rating.
»
Verify you are using the best charger for your batteries.
See your local hobby dealer for a wide selection of
compatible chargers.
2-SPeed tranSMiSSion
Your Twin Hammers trail racer features a 2-speed
transmission, giving you the option for fast driving or rock
crawling all in one vehicle. To change between speeds:
1. Press the top of the Channel 3 switch for low speed driving.
2. Press the bottom of the Channel 3 switch for high
speed driving.
important:
If you decide to use a transmitter other
than the one included with the vehicle, limit the Channel
3 travel end points and gradually increase the travel until
the vehicle shifts. Failure to limit the travel endpoints will
damage the transmission servo.

After you become familiar with driving
your vehicle, you may need to reset or
make adjustments to the alignment.
Make sure to work on a flat work space.
This will enable you to easily and more
quickly make both Toe-in and Cam-
ber adjustments. These adjustments
should be set with the vehicle sitting
at its normal ride height.
»
Keep your vehicle clean by using a soft brush to remove
dirt and dust.
»
Look for cracks in the suspension arms and other
molded parts.
»
Check the beadlock wheel hardware.
»
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.
• Check the Spur gear for wear.
• Check the Pinion gear.
• Check the Slipper Pads for wear.
»
Take the shocks off the vehicle and check them for leakage.
It may be time to rebuild them.
»
Look over all the wiring and connections for bare
wire or any place that could lead to a short-circuit.
»
Verify 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 4 AA batteries in the transmitter.
The single largest factor in run time is
the mAh capacity of your battery pack.
The larger the mAh rating, the more run
time you will experience. 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. The longer you run, the
hotter the battery plugs can get. Check
the standard plugs periodically. As bat-
teries see more use, they will degrade
in performance and capacity.
How you drive your Twin Hammers
vehicle also affects your run times. If
you are performing runs, going from a
standstill to full speed repeatedly, you
are taxing your batteries and electron-
ics. Hard acceleration draws a lot of
current from any battery and will
lead to shortened run time.
