Brushed vs. Brushless Motors
The included 370 motor is designed for use with
2-cell Lithium Polymer (LiPo) batteries. For extreme
aerobatics and extended hovering, we strongly
suggest upgrading to our E-Flite park 370 motor
(4100KV) (EFLM1000), which is designed to fit into
the existing supplied gearbox and for use with 3-cell
LiPo batteries.
To get the best lifespan from the supplied motor, it
should not be operated with a 3-cell LiPo battery. In
addition, there are a couple more tricks that will also
extend the life of the motor. First, it is suggested to
break-in the motor properly. Place a drop of oil on
both the front and rear bushing of the motor, then
run the motor for a few minutes on a lower voltage
source, such as 4.8 volts. This will seat the brushes
to the commutator, giving the best performance.
Another option, but is slightly more difficult, is to
water-dip the motor while it is running. Although it
takes only a short amount of time (a few seconds vs.
a few minutes as stated earlier), there is a higher risk
of damage to the motor. To perform a water break-in,
simply fill a cup with warm water. remove the motor
from the gearbox, get the motor running, then dip the
motor into the water. Let the motor run under water
for about 10-20 seconds, then remove. the water will
be ever so slightly cloudy because of the material
removed from the brushes. Let the motor run for
another 30-seconds, then remove the battery and dry
the motor. As with both break-in procedures, apply
a drop of oil after break-in. Also apply a drop of oil
after every 5-6 flights for good measure.
Another good way to get good performance is
to use a high-quality speed control to operate the
motor. This will provide the best transition of the
motor speed. In addition, the amount of voltage to
the motor will be slightly higher due to lower internal
resistance of the speed control. Finally, a higher
frequency speed control will get the best performance
of the motor.

1. Apply the decals as shown in the illustration
and on the box. It may be helpful to spray
a mixture of water mixed with 1–2 drops of
detergent onto the airframe so the decals will
be easier to place on the airframe.
