Before beginning assembly, we recommend that you
first break in the motor. Taking the time to do this now
will do a couple of things. First, it will improve the per-
formance and life of the motor and, second, it will give
you a chance to test your radio system, electronic speed
control (ESC) and flight battery before installing them into
the airplane.
❑
1)
Lay the radio system, motor, flight battery, peak
charger and ESC onto your work table.
❑
2)
Charge the flight battery using your peak
charger, following the instructions that were provided
with the charger. Install 8 AA batteries into the Focus 3
transmitter.
❑
3)
Plug the two servo leads and the ESC lead into
their proper slots in the receiver.
❑
4)
Using a soldering iron, carefully solder the ESC
motor leads to the leads preinstalled on the motor. Make
sure to use heat shrink tubing to insulate the solder joint.
❑
5)
Set the motor between the handles of a pair of
needle nose pliers and secure the motor to the handles
using a couple of small rubber bands. This will keep the
motor secure enough for the break-in procedure. See
photo # 1 below.

BREAKING IN THE MOTOR

6)
Turn on the transmitter and plug the flight bat-
tery into the ESC. Make sure that the throttle is at idle
and that the motor is turned off.
❑
9)
Using a couple of paper towels, wipe off the
excess motor spray and oil.
❑
10)
Slowly turn on the motor. Position the throttle
lever to about 1/3 throttle and let the motor run. While
the motor is running, apply a light spray of motor spray
inside the motor openings once every minute, followed
by a small drop of racing oil on each end of the motor
shaft. Do this until the battery is fully discharged.
❑
11)
After the battery has discharged and the motor
has stopped, spray motor spray through the motor open-
ings until the fluid runs clear. Apply a couple of drops of
racing oil to each end of the motor shaft and wipe away
all of the excess using paper towels.

7)
With the motor turned off, test the operation of
the two servos. Both servos should move when you move
the control stick.
❑
8)
Carefully spray a couple of light sprays of mo-
tor spray inside the motor openings and apply a small
drop of racing oil onto each end of the motor shaft. See
photo # 2 below.
IMPORTANT
For longer motor life and continued performance, it's a
good idea to regularly clean the motor. Before doing
this, the motor/gearbox assembly should be removed
from the airplane. Remove the motor from the gearbox
and begin by spraying motor spray onto the motor com-
mutator until the fluid runs clear. Place a couple of
drops of racing oil on each end of the motor shaft and
run the motor at 1/3 throttle while spraying the commu-
tator with motor spray. Run the motor for about 1 minute
then oil each end of the motor shaft and reinstall the
motor/gearbox assembly onto the airplane. This pro-
cess keeps the motor bushings lubricated and the
commutator clean. Complete this task every 30 to 40
flights for best performance.
