Determine a Model’s Power Requirements:

1. Power can be measured in watts. For example: 1 horsepower = 746 watts

2. You determine watts by multiplying ‘volts’ times ‘amps’. Example: 10 volts x 10 amps = 100 watts

3. You can determine the power requirements of a model based on the ‘Input Watts Per Pound’ guidelines found below, using the flying weight of the model
(with batte ry):

NOTE: These guidelines were developed based upon the typical parameters of our E-flite motors. These guidelines may vary depending on other motors and
factors such as efficiency and prop size.

4. Determine the Input Watts per Pound required to achieve the desired level of performance:
Model: 25-size aerobatic/3D airplane

Estimated Flying Weight w/Battery: 4.1 lbs
Desired Level of Performance: 130-150 watts per pound; Lightly loaded 3D models

4.1 lbs x 130 watts per pound = 533 Input Watts of total power (minimum)

5. Determine a suitable motor based on the model’s power requirements. The tips below can help you determine the power capabilities of a particular motor
and if it can provide the power your model requires for the desired level of performance:

Volts x Amps = Watts

• 50-70 watts per pound; Minimum level of power for decent performance, good for lightly loaded slow flyer and park flyer models

• 70-90 watts per pound; Trainer and slow flying scale models

• 90-110 watts per pound; Sport aerobatic and fast flying scale models

• 110-130 watts per pound; Advanced aerobatic and high-speed models

• 130-150 watts per pound; Lightly loaded 3D models and ducted fans

• 150-200+ watts per pound; Unlimited performance 3D models

required to achieve the desired performance

• Most manufacturers will rate their motors for a range of cell counts, continuous current and maximum burst current.

• In most cases, the input power a motor is capable of handling can be determined by:

Average Voltage (depending on cell count) x Continuous Current = Continuous Input Watts
Average Voltage (depending on cell count) x Max Burst Current = Burst Input Watts

HINT: The typical average voltage under load of a Ni-Cd/Ni-MH cell is 1.0 volt. The typical average voltage under load of a Li-Po cell is 3.3 volts. This means
the typical average voltage under load of a 10 cell Ni-MH pack is approximately 10 volts and a 3 cell Li-Po pack is approximately 9.9 volts. Due to variations
in the performance of a given battery, the average voltage under load may be higher or lower. These however are good starting points for initial calculations.

Model: 25-size aerobatic/3D airplane
Estimated Flying Weight w/Battery: 4.1 lbs
Total Input Watts Required for Desired Performance: 533 (minimum)

Motor: Power 32
Max Continuous Current: 42A*
Max Burst Current: 60A*
Cells (Li-Po): 3

3 Cells, Continuous Power Capability: 9.9 Volts (3 x 3.3) x 42 Amps = 416 Watts

3 Cells, Max Burst Power Capability: 9.9 Volts (3 x 3.3) x 60 Amps = 594 Watts

Per this example, the Power 32 motor (when using a 3S Li-Po pack) can deliver up to 594 watts of input power, readily capable of powering a 25-size
aerobatic/3D airplane with the desired level of performance (requiring 533 watts minimum). You must however be sure that the battery chosen for power can
adequately supply the current requirements of the system for the required performance.

Battery Choices:

We recommend Thunder Power Li-Po batteries for the best performance and lowest weight (in some cases Ni-MH 1800-2200mAh high-discharge packs also
make good alternatives at the expense of weight and lower capacity). Some examples of the packs we recommend for use with the Power 32 motor can be
found below:

THP33003SPL2 3300mAh 3-Cell/3S 14.8V 20C PL V2 Li-Po EFLB32003S 3200mAh 3S 11.1V 20C Li-Po, 13 AWG
THP33004SPL2 3300mAh 4-Cell/4S 14.8V 20C PL V2 Li-Po EFLB32004S 3200mAh 4S 14.8V 20C Li-Po, 13 AWG
THP33003SP30 3300mAh 3-Cell/3S 11.1V Pro Power 30C Li-Po
THP33004SP30 3300mAh 4-Cell/4S 14.8V Pro Power 30C Li-Po

Operating Instructions:

1. This brushless motor requires the use of a sensorless brushless speed control. Failure to use the correct speed control may result in damage to the
motor and/or speed co ntrol. Please be sure t h e timing and PWM switching frequency is set pr operly on your controller.

2. When mounting the motor, be sure the correct length of screws are used so damage to the inside of the motor will not occur. We suggest you use
the mounting hardware included with your motor. The use of long screws will damage the motor.

3. You may connect the three motor wires directly to the controller with solder or use connectors such as gold plated brushless bullet connectors
(EFLA241), which will also need to be soldered properly to your wires. The three motor wires can be connected in any order to the three output
wires or output port on a sensorless brushless speed control. Be sure to use heat shrink tubing to properly insulate the wires so the wires will not
short. Shorting may damage the motor and speed control.

4. If you add connectors and you no longer wish to use them, never cut the motor wires. Remove them by properly desoldering them. Shortening the
motor wires is considered an improper modification of the motor and may cause the motor to fail.

5. When you connect the motor to the esc, check the rotation direction of the motor. If you find the rotation is reversed, switching any two motor
wires will reverse the direction so the motor rotates properly.

6. Proper cooling of the motor is very important during operation. New technology has brought much higher capacity batteries with higher discharge
rates, which can cause extreme motor temperatures during operation. It is the responsibility of the user to monitor the temperature and prevent
overheating. Overheating of the motor is not covered under any warranty.

7. You can install the propeller on the motor shaft after you have confirmed proper rotation direction. Also consult the instruction included with your
sensorless electronic speed control for proper adjustments and timing.

8. Once the battery is connected to the motor, please use extreme caution. Stay c lear of the rotating propeller since s pinning propellers are very
dangerous as the motors produce high amounts of torque.

9. Never disassemble the motor. This will void any warranty.

Reversing the Shaft:

This Outrunner motor has a shaft, which exits through the rotating part of the motor. If you want to reverse the shaft to exit through the fixed part of the motor,
follow these instructions carefully for changing the shaft installation. Be sure to use the correct sized wrench or you may strip the set screw. NOTE: The user
assumes all liability for damage that may occur.

1. Loosen the set screw on the shaft collar and remove the collar from its location against the bearing.

2. Remove the small black donut washer that rests against the bearing.

3. Loosen the two set screws in the rotating part of the motor.

4. Slide the shaft through the motor. It may be necessary to use a small hammer to lightly tap the shaft. It is very important that you do not bend the
shaft in this process so use extreme caution to assure this does not happen.

5. Re-install the donut washer against the bearing. Do not skip this step.

6. Re-install the shaft collar back against the washer and bearing.

7. Retighten all setscrews making su re you line up with the flat spot on the shaft.

Replacement shafts are available separately. Order EFLM40321 for a Power 32 BL Outrunner shaft.

improper use of propellers may result in serious injury.

Installation:

NOTE: Photo shows typical installation of motor and x-mount directly to the outside of the firewall. There are other options available including mounting the

motor inside the fuselage (requires reversing the shaft direction) or extending the motor further forward using aftermarket mount extensions when using cowls.

1. You can first trial fit the aluminum x-mount against the front of the firewall and use a Sharpie® to mark the locations of four holes and drill
appropriate size hole to fit the blind nuts provided. Always be sure to maintain the proper thrust line and account for adequate prop/spinner
clearance.

2. Attach aluminum x-mount to the outrunner motor using the four flat head (countersunk) screws provided with the motor.

3. Install four blind nuts on the inside of the firewall.

4. Attached the aluminum x-mount and motor to the outside of the firewall using the four socket head cap screws and washers.
