Propeller Direction and Mounting
There are 2 spinning directions for Nanohawk propellers, Clockwise (CW) and
Counter-Clockwise (CCW). When Buying a set of propellers, 2 CW and 2 CCW will
be given. The blunt leading edge indicates the direction the propeller is suppose to
rotate as compared to the sharp trailing edge. When mounting propellers please
make sure the correct orientation shown in the diagram below.
Caution: Failure to mount the propellers in the correct orientation will cause
Nanohawk to not fly correctly and with no control. Please double check for the
correct orientation.
1. Line up the 3 struts of the propeller with the 3 struts on the motor bell.
2. Press on the propeller while supporting the backside of the motor with our
fingers.
3. Press on until the motor shaft is flush with the propeller.

Caution: Failure to support the motor sufficiently can cause the frame to break. Use
caution when pressing the propellers on.
Propeller Dismount
Use caution when dismounting the propellers. Only do so if completely necessary to
change to a new propeller.
1. Use a small tool (such as a 1.5mm hex wrench or the small screwdriver
provided) to press on the metal on the bottom of the motor and Nanohawk.
2. Press on the blades of the propeller with your fingers until the propellers pop
off the motor.
Caution: Failure to support the motor sufficiently can cause the frame to break. Use
caution when pressing the propellers off.

Nanohawk All-in-One Flight Controller
Nanohawk’s main electronic board is shown above. This board contains a F4 flight
controller with all 4 esc’s and an 8CH receiver.
Emax On-Board Receiver
The receiver is integrated into the main flight controller board and is set up via
betaflight.
Number of Channels: 8CH
Compatibility: Receiver mode is SPI RX default protocol is FrSky_D (D8).
NOTE: It is also compatible with Frsky_X (D16) but for best performance it is
recommended to use Frsky_D and set “Telemetry” OFF on your radio.
Binding Procedure
Binding is the process of uniquely associating a receiver to a transmitter module. A
transmitter module can be bound to multiple receivers (not to be used
simultaneously). A receiver can only be bound to one transmitter module.
1.Hold the bind button for 2 seconds while the flight controller is already on. When
the BLUE LED is on, it means the receiver is in BIND MODE
2.Turn on the transmitter, make sure it is set to D8 mode, and then set it into bind
mode. When the BLUE LED on the flight controller starts flashing, it means bind
successful.
3.Power cycle the flight controller and take your radio out of bind mode.
