Six-Series Brushless 2000Kv Motor (28mm x 36mm)
Thank you for purchasing the E-flite Six-Series Brushless 2000 Kv Motor. Six-Series Brushless 6-pole motors
are high torque motors suitable for either direct drive or geared applications. They feature the same diam eter
and mounting hole pattern as brushed 400 and 480 motors so they make excellent upgrades for these cla s ses
of models. Six-Series motors are ideal for direct drive applications such as hotliners and other LMR products
18- to 28-ounces. They are also ideal for 3D and aerobatic models weighing 28- to 35-o unces, and for scale
park flyers weighing 25- to 40-ounces, when using a gearbox. They’re an especially good match for the
ParkZone F-27B Stryker (PKZ1200), flying wings and hotliners when used direct drive, and for aerobatic and
3D models like the E-Flite Brio 10 (EFL2275) when using a gearbox.
Six-Series BL 2000Kv Motor (28mm x 36mm) Features:
• Perfect match for 3D and aerobatic models 28- to 35-ounces (790- to 990-grams) using a gearbox
• Ideal for scale park flyers 25- to 40-ounces (710- to 1140-grams) using a gearbox
• Ideal direct drive motor in models 18- to 28-ounces (510- to 800-grams)
• Ideal for models requiring up to 300 watts of power
• Perfect upgrade for brushed 400 and 480 motors with same diameter and mounting hole pattern
• High Torque, 6-pole slotted rotor design
• Includes connectors, prop adapter, and mounting hardware
• High quality construction with ball bearings and hardened steel 3.2mm shaft

Installation of Pinion Gear & Gearbox:
It will be necessary for you to install the pinion on the shaft if you are using a gearbox.
When installing motors into the E-flite gearbox, it is very important that your gear mesh is correct and the gear’s
mesh is smooth with no binding. The E-flite gearbox features adjustable slotted mounting holes so that you can
ensure your gear mesh is correct. Remember, if your mesh is too loose or too tight, it may strip the gears.
One suggestion may be to insert the polybag included with the motor or a small piece of paper in between the
pinion and spur gear as you are installing them. Tighten and secure the screws to the gearbox. Always make
sure the screws are long enough so they have properly seated into the motor. You can easily pull the polybag
or paper out by rotating the shaft until it comes out. Be certain to check the mesh at multiple points on the spur
gear before finalizing the motor mounting position in the gearbox. To extend the life of your gearbox, we also
recommend using a small amount of grease, such as lithium grease, on the spur gear.
Once a pinion is installed on the shaft, it will be necessary to remove the pinion from the motor shaft if you want
to use the motor with a gearbox that uses a different module of spur gear. If not, the gears may bind and the
motor will not operate properly. We recommend using a gear puller for this step (EFLA212) for the safest
removal of the pinion gear. Never reuse a pinion gear that has been removed from a shaft.
Installing Pinion Gear
1. Align pinion on end of shaft and press fit using a vise for proper installation.
2. Support the aft bearing and shaft using a small hardwood block to prevent both from separating from the
case.
3. Be careful you do not crimp the motor wires in the process and make sure they are safely out of the way.
NOTE: For a more secure press fit, you may add Loctite® Threadlocker Green to the inside of the pinion before
installation.
Removing Pinion Gear
1. To remove the pinion gear, it is recommended to always use a gear puller to prevent damage to the
pinion and shaft. We recommend the E-flite Pinion Puller (EFLA212).
NOTE: Never reuse a pinion gear once it has been removed from the shaft.
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 control.
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 prope rly 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 th e 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 clear of the rotating
propeller since spinning propellers are very dangerous as the motors produce high amounts of torque.
9. Never disassemble the motor. This will void any warranty.
