INSTALL THE BRUSHLESS ESC
Mount your ESC in the desired location. Always make sure that the
ESC is positioned so that it gets some cooling air fl owing over it.
Use the instructions included with the ESC to correctly connect
the ESC.

RIMFIRE MOTOR MAINTENANCE
RimFire brushless motors require virtually no maintenance. There are
no brushes to wear out and replace. The precision bearings have a
very long service life and should last a very long time. The internal
parts of the motor should not require any cleaning. The only thing that
needs to be checked is to make sure all the screws and set screws
remain tight.

IMPORTANT PRECAUTIONS
• Once the battery is connected to the ESC, stay clear of the motor
and prop.
• DO NOT apply an input voltage that exceeds the maximum
specifi cation of each motor.
• DO NOT apply currents to the motor that exceed the maximum
specifi cations of each motor.
• DO NOT allow the input connectors to accidentally touch each other
while power is applied to the motor. Make sure all input connections
are insulated electrically.
• DO NOT allow water or moisture to enter the motor, as it can
cause permanent damage to the motor and possibly short out the
attached ESC.
• DO NOT cut the coated wires from the motor. If you must remove the
bullet connectors, unsolder them.
• Allow the motor to cool after each fl ight.
• The motor shaft of the motor will rotate at very high rpm. DO
NOT attempt to touch the shaft while it is rotating. If setting up
the motor/ESC on the workbench, make sure the motor is securely
attached and that nothing is attached to the motor shaft BEFORE
applying power.
• NEVER attempt to use a damaged motor (having mechanical or
electrical defects).

Front Of Firewall Mounting Method
Use the template from the
header card to locate and drill
the mounting holes and the
relief holes for the mounting
plate screws. Attach the
RimFire mounting plate to the
fi rewall using three #4
Ч3/8”
[3
Ч6mm] sheet metal screws
(not included), or a type/
size specifi ed by the airplane
manual.
Behind Firewall Mounting Method
Use the template from the
header card to locate and drill
the holes for the mounting
screws. Attach the RimFire
mounting plate to the fi rewall
using three 3mm machine
screws (not included).
Prop Saver Prop Adapter Installation
Install the cowl if the plane
comes with one. Install the
prop on the prop saver and
secure it with a rubber O-ring
looped over both of the
machine screws. Check the
O-ring for wear before each
fl ight. If the O-ring shows any
cracks, replace immediately.
Collet Type Prop Adapter Installation
Slide the 3mm prop shaft
over the motor shaft. Next
slide the prop shaft retainer
over the prop shaft. Note that
the hole through the retainer
is tapered. Make sure that the
side with the larger diameter
hole is installed fi rst. Install
the prop, prop washer and
then the prop nut. Tighten the
prop nut against the prop. This will cause the tapered hole in the prop shaft
retainer to squeeze the prop shaft around the output shaft. Carefully pull on
the prop to make sure it is securely attached to the motor shaft.
Set Screw Type Prop Adapter Installation
Slide the 3mm prop adapter
over the motor shaft. Tighten
both of the set screws against
the shaft. Install the prop,
prop washer and then the
prop nut. Tighten the prop
nut against the prop. Carefully
pull on the prop to make sure
it is securely attached to the
motor shaft.
Remove the set screw
that locks the motor shaft
to the front endbell.
Loosen the set screw
in the brass collar and
slide it off the back of the
motor shaft.
Remove the c-clip and
washers from the motor
shaft behind the rear
endbell.
Press the motor shaft
forward inside the motor.
Reinstall the washers and
c-clip onto the groove at
the back of the motor
shaft. Rotate the shaft
inside the motor so that
the hole for the set screw
in the front endbell aligns
with the fl at spot on the
shaft. Reinstall the set
screw into the front endbell and tighten it against the shaft with thread
locking compound.
The included prop saver
adapter can be installed
with either end facing
forward. One end has a
diameter of 5mm and the
other end has a diameter
of 6mm. For other prop
hub sizes, 7mm and
7.85mm adapter sleeves
are also included to fi t
over the 5mm diameter prop saver end. Orient the prop saver adapter
in the direction that best suits your propeller and install it onto the
front of the motor shaft and tighten the screws against the fl at spots
on the shaft.
Mounting Plate Installation
Although the mount-
ing plate comes prein-
stalled on the RimFire,
the three 3
×4mm ma-
chine screws should
be retightened with
threadlocking com-
pound. If you plan to
install the motor behind
the firewall, remove the
mounting plate from
the motor.
