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

Tinyhawk II Race All-in-One Flight
Controller
Tinyhawk II Race’s main electronic board is shown above. This board contains a F4
flight controller with all 4 esc’s and an 8CH receiver.
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).
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 RED LED is flashing, 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.
Alternate Binding Method

Page 12
Tinyhawk II Race
It is possible to place the receiver into Bind Mode via the Betaflight configurator.
In the CLI tab type in this command:
bind_rx
Hit enter and your receiver should be in bind mode. Follow steps 2-3 from
above to complete the binding process.
Emax Tinyhawk II Race Flight Controller (FC)
This flight controller has a F4 MCU with a MPU6000 gyro. Tinyhawk II Race flight
controller comes pre-programmed and properly tuned for optimal flight. The flight
controller is programmed with Betaflight 4.1.0. 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
Tinyhawk II Race 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 Tinyhawk II Race 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 an 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.
Adjusting Software Settings (Betaflight Configurator)
Betaflight Configurator can be used to changed programmed settings on Tinyhawk II
Race and to flash new firmware if desired. Betaflight Configurator and flight controller
firmware can be downloaded at https://github.com/betaflight/. The hardware target for
Tinyhawk II Race Flight Controller is MatekF411RX.
DISCLAIMER: We do not suggest changing any PID settings on Tinyhawk II Race or
upgrading the firmware to new versions. Tinyhawk II Race comes stock with an
optimal tune for superior flight performance. Changing this can affect flight time,
overall speed, control of the aircraft, and excessive heat within the motors.
Reprogramming Tinyhawk II Race Flight Controller
1. Put the Flight Controller in DFU mode by pressing the BOOT button while
plugging in the micro USB cable to a computer.
2. Select MATEKF411RX as the target and then select the firmware (4.1.0) or

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 throttle and yaw direction of Tinyhawk II Race. The right stick
controls pitch and roll of the aircraft.
Left Stick Diagram
Right Stick Diagram
Fly Tinyhawk II Race
Start by powering on your Radio and Goggles. Tinyhawk II Race comes already
bound to your radio and on the right video channel matched with your goggles.
Power on Tinyhawk II Race by sliding the battery into the battery tray and plugging it
in. Once the battery is plugged in, set Tinyhawk II Race on a stable surface so it can
calibrate. Calibration takes a few seconds then Tinyhawk II Race is ready to fly.
Tinyhawk II Race can fly for 4 minutes on a fully charged battery. Land Tinyhawk II
Race when the battery reaches 3.2v; flying any longer can severely damage your
battery and is not recommended.

Tinyhawk II Race
Arming
Arming refers to setting Tinyhawk II Race to a fly ready state. When Tinyhawk II
Race is powered on first it will not spin up the propellers until it is armed. Arm the
aircraft by first moving throttle to the bottom position. Then move the left switch of the
radio to its 3rdposition upwards. You will see the propellers spinning when Tinyhawk
II Race is successfully armed.
In the event of a crash always disarm immediately. Failure to disarm in a timely
manner can damage Tinyhawk II Race.
Always disarm Tinyhawk II Race before handling it.
Flying Modes
Tinyhawk II Race 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, Tinyhawk II Race will be in
angle mode where control sets the attitude of the aircraft. When the switch is in the
middle state, Tinyhawk II Race will be in Horizon mode.
Line of Sight Flying
To learn how to fly Tinyhawk II Race start by flying it line of sight (no goggles yet).
Power on Tinyhawk II Race and set it down in a cleared room. Arm Tinyhawk II Race
then throttle up using the left stick to a hover position. Work on maintaining a
constant altitude. Pitch and roll Tinyhawk II Race with the right thumb stick and yaw
Tinyhawk II Race with the left thumb stick.
First Person View (FPV) Flying
Make sure Tinyhawk II Race and the goggles are on the same vtx channel and that
you have a clear area to fly around in. Apply the same principals learned when flying
Tinyhawk II Race 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 Tinyhawk II Race like a car using yaw on the left
thumb stick.
There is an on screen display (OSD) overlaying the video feed from the camera of
Tinyhawk II Race. 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. Tinyhawk II Race can fly for a maximum of 4 minutes. When the
battery reaches 3.2v, land Tinyhawk II Race. Drawing the battery below 3.2v is not
suggested and can damage the battery.
