Nanohawk Structure

Nanohawk

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 supposed 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. 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. 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 successfully.
3. Power cycle the flight controller and take your radio out of bind mode.

Alternate Binding Method

It is possible to place the receiver into Bind Mode via the Betaflight configurator.
In the CLI tab type in this command: bind_rx_spi
Hit enter and your receiver should be in bind mode. Follow steps 2-3 from above to complete the binding process.

Emax Nanohawk Flight Controller (FC)
This flight controller has a F4 MCU with a MPU6000 gyro. Nanohawk flight controller comes pre-programmed and properly tuned for optimal flight. For a full tune and configuration setting file (CLI dump file) please visit <https ://emax-usa.com/> for the CLI dump file.

Stock Flight Controller Settings
Nanohawk is configured to take a channel map of the TAER1234 convention. That is the channel map is in the respective order: throttle, aileron, elevator, rudder, AUX 1, AUX 2, AUX 3, and AUX 4. The arm switch on Nanohawk is set on AUX 1 and armed with the highest value. AUX 2 is configured for a 3  stage switch to select flight modes: Acro, Horizon, and Angle activating in increasing order. AUX 3 is configured for the beeper. In a high state, the motors will beep. AUX 4 is set to Flip Over After Crash mode (often referred to as turtle mode). Turtle mode is set when AUX 4 is in a high state. Please configure your radio as described above or change these settings in Betaflight Configurator.

Flight

Always use caution when flying and operate in an open and controllable area. Please learn the flight controls first before powering on the aircraft to fly.

Radio Stick Controls

The left stick controls the throttle and yaw direction of Nanohawk. The right stick controls pitch and roll of the aircraft.

Fly Nanohawk

Start by powering on your Radio and Goggles. Nanohawk comes already bound to your radio and on the right video channel matched with your goggles. Power on Nanohawk by sliding the battery into the battery tray and plugging it in. Once the battery is plugged in, set Nanohawk on a stable surface so it can calibrate.

Calibration takes a few seconds then Nanohawk is ready to fly. Nanohawk can fly for 4 minutes on a fully charged battery. Land Nanohawk when the battery reaches 3.2v; flying any longer can severely damage your battery and is not recommended.

Arming

Arming refers to setting Nanohawk to a fly-ready state. When Nanohawk is powered on first it will not spin up the propellers until it is armed. Arm the aircraft by first moving the throttle to the bottom position. Then move the left switch of the radio to its 3rd position upwards. You will see the propellers spinning when  Nanohawk is successfully armed.

In the event of a crash always disarm immediately. Failure to disarm in a timely manner can damage Nanohawk.

Always disarm Nanohawk before handling it.

Flying Modes
Nanohawk comes stock set in rate mode. This is an advance mode where control sets the angular rate of the aircraft. The AUX 2 switch is set to change this mode on a 3 stage switch. When AUX 2 is in a high state, Nanohawk will be in angle mode where control sets the attitude of the aircraft. When the switch is in the middle state, Nanohawk will be in Horizon mode.

Line of Sight Flying
To learn how to fly Nanohawk start by flying it line of sight (no goggles yet). Power on Nanohawk and set it down in a cleared room. Arm Nanohawk then throttles up using the left stick to a hover position. Work on maintaining a constant altitude. Pitch and roll Nanohawk with the right thumb stick and yaw Nanohawk with the left thumb stick.

First Person View (FPV) Flying
Make sure Nanohawk and the goggles are on the same vtx channel and that you have a clear area to fly around in. Apply the same principles learned when flying  Nanohawk line of sight except now work on flying in a forward direction while maintaining a controlled constant altitude. It is easier to learn flying FPV by always moving in a forward direction so always apply a slight amount of pitch using your right thumb stick. You can steer Nanohawk like a car using a yaw on the left thumbstick.
There is an on-screen display (OSD) overlaying the video feed from the camera of Nanohawk. The OSD displays important information such as flight time and battery voltage. Pay attention to these numbers during flight to know how much battery life is left. Nanohawk can fly for a maximum of 4 minutes. When the battery reaches 3.2v, land Nanohawk. Drawing the battery below 3.2v is not suggested and can damage the battery.

Tips: Work on maintaining a controlled altitude flight to begin while driving Nanohawk with pitch and yaw. Do not let the battery go lower than 3.2v. The arm switch activates a beeper when set in the 2nd position (middle); this is useful when looking for Nanohawk.

Thank you for purchasing our product! Enjoy Flying Nanohawk.
