Great Planes Ammo 36mm Power System - GPMG5240-5325 - Manual (Page 6)

SET SCREW TYPE PROP ADAPTER
INSTALLATION
Slide the prop adapter over the output shaft of the gear
drive or motor. Align one of the set screws with the flat on
the output shaft of the gear drive. Apply a drop of
threadlocker to the set screw and install it in the prop
adapter, tightening it against the flat of the gear drive output
shaft. Remove the second set screw that does not tighten
onto the flat. When installing the prop adapter onto a shaft
that does not have a flat spot, tighten both of the set screws
against the shaft. Install the spinner backplate (if used, not
included), 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 output shaft
of the gear drive.
Determine the distance the prop adapter needs to be from
the firewall by using the recommended distance in the
airplane instructions or by installing the cowl and measuring
the distance from the firewall to the front of the cowl. Add
approximately 3/32" to 1/8" to the distance. Attach the Front
Plate of the motor mount to the Back Plate using the eight
6-32x1/2" SHC screws, eight #6 flat washers and four
aluminum screw plates, spaced out as far as possible. A
drop of Threadlocker on the threads of the screws will
prevent the screws from coming loose.
MOTOR BRACKET INSTALLATION
(OPTIONAL)
The Large Motor Mount comes with an optional Motor
Bracket. If you have installed a 40mm or longer motor in the
Motor Mount; we recommend installing the optional Motor
Bracket. Attach the Motor Bracket to the sides of the Motor
Mount using two 4-40x1/2" SHC screws, #4 flat washers
and 4-40 lock nuts. Position the Motor bracket as far back
on the motor as possible. Once the Motor Bracket is
installed, secure the motor to the Motor Bracket using the
nylon strap.
INSTALL THE BRUSHLESS ESC
Because most of the power systems using the 36mm
Ammo motor are drawing more than 35 amps continuous,
the ElectriFly SS-45 Brushless ESC (GPMM1840), for
power systems drawing less than 45 amps, works well. If
you will be using an Ammo motor and prop combination
that draws more than 45 amps continuous, use the SS-60,
SS-80 or SS-100 Brushless ESC. Always make sure that
the ESC is positioned so that it gets some cooling air
flowing over it.
Use the instructions included with the brushless ESC to
correctly connect the ESC.
AMMO MOTOR MAINTENANCE
Ammo 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.
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 specification of each motor.
• DO NOT apply currents to the motor that exceed the
maximum specifications 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 flight.
• 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).
