Slipper Clutch Break-In
The E-Revo 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.
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 3000mAh battery pack will theoretically
run twice as long as a 1500mAh 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 impossible to give exact run times
for the model.
Another major factor that affects run time is how the model is driven.
Run times may decrease when the model is driven repetitively from a
stop to top speed and with repetitive hard acceleration.
Tips for Increasing Run Time
• Use batteries with the highest mAh rating you can purchase.
• Use a high-quality peak-detecting charger.
• Read and follow all maintenance and care instructions provided by
the manufacturer of your batteries and charger.
• Keep the MXL-6s cool. Get plenty of airflow across the ESC.
• Lower your gear ratio. Installing smaller pinion gears will lower
your gear ratio and cause less power draw from the motor and
batteries, and reduce overall operating temperatures. Always
replace both pinion gears together.
• Vary your speed. Continuous high-speed, high-gear running
shortens the run time on the E-Revo.
• Maintain your model. Do not allow dirt or damaged parts to cause
binding in the drivetrain. Keep the motor clean.
mAh Ratings and Power Output
The mAh rating of the battery can effect your top-speed performance.
The higher capacity battery packs experience less voltage drop under
heavy load than low mAh rated packs. The higher voltage potential
allows increased speed until the battery begins to become discharged.
RUNNING IN WET CONDITIONS
Your new Traxxas model is designed with water-resistant features
to protect the electronics in the model (receiver, servos, electronic
speed control). This gives you the freedom to have fun driving your
model through puddles, wet grass, snow, and through other wet
conditions. Though highly water resistant, the model should not be
treated as though it is submersible or totally 100% waterproof. Water
resistance applies only to the installed electronic components. Running
in wet conditions requires additional care and maintenance for the
mechanical and electrical components to prevent corrosion of metal
parts and maintain their proper function.
Precautions
• Without proper care, some parts of your model can be seriously
damaged due to contact with water. Know that additional
maintenance procedures will be required after running in wet
conditions in order to maintain the performance of your model.
Do not run your model in wet conditions if you are not willing to
accept the additional care and maintenance responsibilities.
