Tinyhawk II Freestyle All-in-One Flight Controller

Tinyhawk II Freestyle’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).

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

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 Tinyhawk II Freestyle Flight Controller (FC)

Left Stick Diagram

Fly Tinyhawk II Freestyle

Start by powering on your Radio and Goggles. Tinyhawk II Freestyle comes already bound to your radio and on the right video channel matched with your goggles.
Power on Tinyhawk II Freestyle by sliding the battery into the battery tray andplugging it in. Once the battery is plugged in, set Tinyhawk II Freestyle on a stable
surface so it can calibrate. Calibration takes a few seconds then Tinyhawk II Freestyle is ready to fly. Tinyhawk II Freestyle can fly for 4 minutes on a fully charged

battery. Land Tinyhawk II Freestyle when the battery reaches 3.2v; flying any longer can severely damage your battery and is not recommended.

Arming refers to setting Tinyhawk II Freestyle to a fly ready state. When Tinyhawk II Freestyle 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 3rd position upwards. You will see the propellers spinning when TinyhawkII Freestyle is successfully armed.

In the event of a crash always disarm immediately. Failure to disarm in a timely manner can damage Tinyhawk II Freestyle. Always disarm Tinyhawk II Freestyle before handling it.

Flying Modes

Tinyhawk II Freestyle 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 Freestyle will be in easy mode where control sets the attitude of the aircraft. When the switch is in the middle state, Tinyhawk II Freestyle will be in intermediate mode.

Easy Mode: This is easy flight control where the maximum angle of tinyhawk II Freestyle is limited in flight to help limit speed and make flying easier. In this mode control of the aircraft is attitude based. Input from the right gimbal with pitch and roll controls the pitch and roll angle of the aircraft. For example 20 degrees of tilt on roll of the gimbal will translate to 20 degrees of roll tilt on tinyhawk II Freestyle.

Intermediate Mode: This mode has a higher angle limit for higher speed flying with the same attitude control. The only difference is at the end of the gimbal for pitch and roll, it will cause the aircraft to flip in that direction.

Advance Mode: This mode gives you full control of the aircraft. There is no more angle limit and control is rate based. This means control input from the gimbal sets a
rotation rate on said axis.

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

First Person View (FPV) Flying
Make sure Tinyhawk II Freestyle 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 Freestyle 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 Freestyle 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 Freestyle. 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 Freestyle can fly for a maximum of 4 minutes. When the battery reaches 3.2v, land Tinyhawk II Freestyle. 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 Tinyhawk II Freestyle 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 whenlooking for Tinyhawk II Freestyle.

Warning：

Please pay attention to your surroundings.
Not recommended for persons under 18 years of age.
