Great Planes GPMG4500 User Manual

ElectriFly’s™RimFire™22M-1000 brushless motors are designed and produced with high quality , po wer, precision and efficiency
in mind. Designed to be power upgrades for smaller 3D aerobats and flat-foamies, the “outrunner” design eliminates the need
for an external gear drive for many applications. And, RimFire’s prop-saver design eliminates the need for a prop adapter for
many applications – simply strap the prop onto the motor with a rubber O-ring and that’s it!

• Great for small high performance airplanes, from flat foams to
built-up 3D’s.

• RimFire’s prop mounting system eliminates the need f or a prop
adapter for many applications.

• Outrunner design often eliminates the need for using external
gear drives for many applications.

• Very reliable and virtually maintenance free. No brushes to
wear out.Dual ball-bearings are shielded on both sides to keep
out dirt and debris.

• Exceptionally high power to weight ratio.

• Very durable machined aluminum and iron can.

• Maximum rated efficiency of 77%.

• Extremely strong neodymium “rare earth”magnets for high output
torque, with one of the highest temperature ratings in R/C at
150°C [302°F] which won’t breakdown like lower quality magnets .

• Magnet wires with a maximum 160°C [320°F] temperature rating.

• Gold plated 2mm bullet connectors pre-installed (3 per motor).

• Each motor includes:

• 3 x 5mm, standard thread, round head mounting bolts –
3 each.

• 2.6 x 10mm, standard thread, flat head hex key bolts –
2 each.

• Small #10 rubber O-rings – 6 each.

• Stainless steel output shaft diameter and length: 3 x 12mm.

• Do NOT apply an input voltage that exceeds the maximum
voltage listed in the specifications above.

• Do NOT apply currents to the motor that exceed the maximum
specifications above.

• 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.

• Allow the motor to adequately cool if it becomes hot
during operation.

• The output shaft will rotate at very high RPMs.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 connected to the output shaft
BEFORE applying power.

• Never attempt to use a damaged motor (having mechanical or
electrical defects).

RimFire brushless motors must be controlled with a brushless
electronic speed control. And, RimFire motors are sensorless so
the ESC must be of sensorless design as well. Do NOT attempt
to use RimFire motors with ESCs that are designed for traditional
brushed motors as permanent damage will result!

The BL-8 Brushless ESC from ElectriFly (GPMM2070) is a
perfect match for the RimFire 22M-1000 brushless motor for
small 3D flat-foam airplanes. ESCs with more power may be
better suited when using the RimFire motor in slightly larger
airplanes which require more current/torque. Check your local
hobby retailer for details on different ESC options.

There are two options for mounting the RimFire motor to your
airplane, either in-front or behind the firewall.

The entire motor can be mounted in front of the firewall. This is
the most common method for mounting a motor to a
flat-foam airplane (refer to the airplane’s instruction manual for
details).To mount the motor to the front of the firewall:

❏ 1. Secure the mounting plate to the motor with the three

included 3 x 5mm machine screws.

❏2. Use the printed template shown at left to mark the locations

of the mounting holes in the firewall.

❏ 3. Drill four 5.5mm

holes to clear the three
machine screws and
motor shaft through the
firewall, and drill three
pilot holes for mounting
the motor to the firewall
with wood screws as
shown here.

❏ 4. The prop will be installed on the motor’s built-in prop-saver

on the rotating section of the can. It will not be necessary to use
the included prop-adapter for this application. Install the two
included 2.6 x 10mm machine screws into the two holes on the
side of the motor’s built-in prop-saver. Make sure the screws are
tight, but do not overtighten the screws as they could strip the
threads inside the prop-saver!

❏ 5. The prop-saver is designed for use with APC Slo-Flyer

props. Press the larger of the two adapter rings included with the
propeller into the ACP Slo-Flyer prop hub and press the prop onto
the prop-saver.

❏6.Use one of the included rubber

O-rings to secure the propeller to
the screws on the prop saver. For
high-power applications, use two
O-rings for a stronger mount.

The motor can be installed behind a firewall.To do so:

❏1. Use the printed template shown on the rev erse page to mark

the mounting holes on the firewall.

❏ 2. Following the template, drill three 3mm holes (for the

mounting screws) and one 10mm hole (for the output shaft)
through the firewall.

❏3.Secure the motor to the firewall

using the three included 3 x 5mm
machine screws. If the firewall is
very thick it may be necessary to
use longer screws (not provided).
Here, the long end of the motor’s
shaft will protrude forward through
the firewall.

❏ 4. The included prop adapter will need to be installed onto the

motor’s long shaft as it protrudes through the firewall.There is no
need to install the 2.6 x 10mm machine screws into the two holes
on the side of the motor’s built-in prop-saver for these installations.

❏ 5. Remove the prop nut and

prop washer from the prop
adapter and slip the prop adapter
onto the shaft. Install the propeller
on the prop adapter.Re-install the
prop washer and prop nut.Tighten
the prop nut. This will cause the
collet to tighten down and grip the
motor’s shaft.

IMPORTANT! Always make sure the motor is mounted firmly to
the aircraft to prevent it from accidentally coming loose when
power is applied to the system!

When all motor/ESC connections are complete, make sure the
motor connections are not touching each other while power is
applied, as permanent damage to the motor/ESC could result.
Make sure all input connections are insulated electrically.
Installing heat-shrink tubing over each connection is
recommended. Do not attempt to cut or remove any of the input
wires from the motor as it will likely damage the motor beyond
feasible repair.

RimFire motors have three input connectors, each with 2mm
male bullet connectors pre-installed. Connect all three of the
motor’s input wires to the output wires on the ESC. It is not
necessary to match up the colors of the wires on the ESC to the
wires on the motor.If the motor operates in the opposite direction
as required, switch any two of the wires from the ESC to the
motor to reverse the motor’s rotation.

RimFire brushless motors require virtually no maintenance.There
aren’t any brushes to wear out and replace. The ball-bearings
have a very long service life and should maintain good operating
condition for a very long period of time. Blowing pressurized air
into the motor can help to remove dirt and debris, and improve
overall efficiency. The output wires should not require
replacement. If used with a gear drive, the gear drive itself might
require addition of lubricating grease after a certain period of
time. See the instructions which came with your gear drive for
detailed information.
