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 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:
1. Use batteries with the highest mAh rating you can purchase.
2.Use a high-quality peak-detecting charger.
3. Read and follow all maintenance and care instructions provided by the manufacturer of your batteries
and charger.
4.Keep the ESC cool. Get plenty of airflow across the ESC heat sink.
5.Lower your gear ratio. Installing a smaller pinion gear will lower your gear ratio and cause less power
draw from the motor and batteries,and reduce overall operating temperatures.
6.Maintain your model. Do not allow dirt or damaged parts to cause binding in the drivetrain. Keep the
motor clean.
Precautions:
1.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.
2.Not all batteries can be used in wet environments. Consult your battery manufacturer to see if their
batteries can be used in wet conditions. Do not use LiPo batteries in wet conditions.
3.The transmitter is not water resistant. Do not subject it to wet conditions, such as rain.
4.Do not operate your model during a rain storm or other inclement weather where lightning may be present.
5.Do not allow your model to come in contact with saltwater, brackish water, or other contaminated water.
Saltwater is highly conductive and highly corrosive. Use caution if you plan to run your model on or near
a beach.
6.Even casual water contact can reduce the life of your motor. Special care must be taken to modify your
driving style in wet conditions to extend the life of the motor.
Motor Precautions:
1.B-G550 775 motor life can be greatly reduced in mud and water. If the motor gets excessively wet or
submerged, use very light throttle (run the motor slowly) until the excess water can run out. Applying full
throttle to a motor full of water can cause rapid motor failure. Your driving habits will determine motor life
with a wet motor. Do not submerge the motor under water.
2.Do not gear the motor by temperature when running in wet conditions. The motor will be cooled by water
contact and will not give an accurate indication of appropriate gearing.
Additional Maintenance:
Increase your frequency of disassembly,inspection, and lubrication of the following items. This is necessary
after extended wet use or if the vehicle will not be used for an extended period of time (such as a week or
longer). This additional maintenance is needed to prevent any trapped moisture from corroding internal
steel components.
