DECISIONS YOU MUST MAKE
At this point, based on the performance table from page 2
and the airplane you will install the HyperFlow ducted fan
into, you will need to decide which motor, ESC, and batteries
to use with the fan. Remember that once a motor is chosen
based on the power output, a speed controller and battery
must be used that are capable of delivering the current
drawn by the motor. Several power systems are available
from Great Planes at the time of this printing. Please check

ADDITIONAL ITEMS REQUIRED
❏
Threadlocking compound (GPMR6060)
❏
Phillips screwdriver (HCAR1024)
❏
1.5mm hex wrench (GPMR8010)
❏
Medium CA+ glue (GPMR6008)
The EP Ducted Fan Unit will work with 370 sized brushed
motors, 20mm brushless motors, and 24mm brushless
motors. All necessary parts are included for these motor
installations, plus 2mm, 2.3mm, and 3mm adapters.
Note: The aft cone might not be installed when using longer
brushless motors.
If your motor does not already have leads attached, do so
prior to the motor installation into the ducted fan unit.
NOTE: If the ducted fan application requires the fan housing
to be installed into an existing duct tube that provides properly
distributed airfl ow into the fan rotor, then the optional rotor cone
should not be installed. If the ducted fan is to be installed in a
nacelle or into a duct tube that does not properly direct airfl ow
into the fan rotor, the optional rotor cone should be installed.
ASSEMBLY
Installing a Brushed Motor
❏
1. If installing a Great Planes T-370 brushed motor, slide
the motor into the ducted fan housing up to the mounting
plate. Align the slotted motor mounting holes in the housing
with the screw holes at the top of the motor.
❏
2. Secure the motor to the fan housing using two 3 x 5mm
fl at head screws with threadlocking compound.
