DRIVING YOUR MODEL
Now it’s time to have some fun! This section contains instructions on
driving and making adjustments to your model. Before you go on,
here are some important precautions to keep in mind.
• Allow the model to cool for a few minutes between runs. This is
particularly important when using high capacity battery packs
that allow extended periods of running. Monitoring temperatures
will extend the lives of the batteries and motor.
• Do not continue to operate the model with low batteries or you
could lose control of it. Indications of low battery power include
slow operation and sluggish servos (slow to return to center).
Stop immediately at the first sign of weak batteries. When the
batteries in the transmitter become weak, the red power light will
begin to flash. Stop immediately and install new batteries.
• Do not drive the model at night, on public streets, or in large
crowds of people.
• If the model becomes stuck against an object, do not continue to
run the motor. Remove the obstruction before continuing. Do not
push or pull objects with the model.
• Because the model is controlled by radio, it is subject to radio
interference from many sources beyond your control. Since radio
interference can cause momentary losses of control, allow a safety
margin of space in all directions around the model in order to
prevent collisions.
• Use good, common sense whenever you are driving your model.
Intentionally driving in an abusive and rough manner will only
result in poor performance and broken parts. Take care of your
model so that you can enjoy it for a long time to come.
• High performance vehicles produce small vibrations which may
loosen hardware over time. Frequently check wheel nuts and
other screws on your vehicle to ensure that all hardware remains
properly tightened.
Slipper Clutch Break-In
The E-Maxx Brushless Edition’s slipper clutch requires a break-in
procedure to ensure consistent operation with the extremely high
power output of the included MXL-6s brushless motor system. The
slipper clutch has been adjusted to the correct initial setting for
break-in. Follow these steps to ensure maximum performance and
life from your slipper clutch:
1. Make your first runs with the model using the stock gearing and
6- or 7-cell NiMH packs, or 2S LiPo packs.
2. Drive normally. The slipper clutch should slip momentarily
when accelerating aggressively on high-traction surfaces (you
will hear a whirring sound when the slipper clutch allows the spur
gear to slip).
3. If excessive slippage is noticed (slipping that lasts for more
than 3 seconds under hard acceleration), or the slipper clutch
slips anytime the throttle is applied at any lever, stop driving
immediately. Let the slipper clutch cool for 10-15 minutes.
When the clutch is cool, test-drive the vehicle again. If you still
experience excessive slippage, allow the slipper to cool once
more, then tighten the slipper nut ¼ turn (turn the nut clockwise)
and repeat the break-in process. Do not adjust the slipper clutch
before it has cooled.
4. Continue to run the vehicle and monitor slipper clutch
performance as noted above, and readjust if necessary. When the
run is complete, the slipper should be fully broken in.
After break-in, the slipper clutch is ready for any type of driving,
with any batteries up to 6S Lipo. Set the slipper clutch so it only
slips for a moment (if at all) under hard acceleration in high-
traction conditions. If excessive slippage is noticed, stop driving
immediately. Continuing to drive with a loose slipper will cause
damage to the slipper unit. You must let the slipper cool down
to ambient temperature before tightening the slipper nut and
resuming driving.
Make Sure The Axle Nuts Are Tight Before Each Run
Before operating your E-Maxx Brushless
Edition, take a moment to make sure
the axle nuts are tight, as they may have
loosened during shipping. The correct
size axle-nut wrench is supplied with the
truck. Check the tightness of the axle nuts
before each run. The E-Maxx’s high speed
and torque can loosen the nuts over time
if left unchecked.
About Run Time
A large factor affecting run time is the type and condition of
your batteries. The milliamp hour (mAh) rating of the batteries
determines how large their “fuel tank” is. A 3000 mAh battery
pack will theoretically run twice as long as a 1500 mAh sport pack.
Because of the wide variation in the types of batteries that are
available and the methods with which they can be charged, it’s
