7. How To Fly Tinyhawk III

Before turning on the drone, please learn the controls first, and then turn on the drone. Be cautious when flying and operate in an open and controllable area.

(Take EMAX's E8 Transmitter and Transporter 2 Goggles as examples)

First turn on the power of E8 Transmitter and Transporter 2. Tinyhawk III has been bound to E8 Transmitter and matched with your Transporter 2 on the correct video channel. Turn on your Tinyhawk III by sliding the battery into the battery tray and plugging in the power source. After the battery is inserted, place the Tinyhawk III on a level and stable surface so that it can be calibrated.

Calibration takes a few seconds, and then Tinyhawk III can fly. Tinyhawk III can fly for up to 4 minutes when the battery is fully charged. When the battery power reaches 3.2v, please land the Tinyhawk III; flying longer will seriously damage your battery and is not recommended.

7.1 Lock&Unlock

Arming refers to setting Tinyhawk III to begin flying. When Tinyhawk III is powered on for the first time, it will not spin the propeller until it is armed.

First move the throttle to the bottom position to control the aircraft,
Then move the left switch of the E8 Transmitter to the third position.

When Tinyhawk III is successfully armed, you will see the propellers spinning.

Note: In the event of a collision, Tinyhawk III must stop flying immediately. Failure to stop the flight in time will damage Tinyhawk III. Before handling Tinyhawk III, be sure to switch the switch to an unarmed position. 7.2Flight Mode

The AUX 2 switch is set as a 3-level switch to change this mode. When AUX 2 is in the first position, Tinyhawk III will be in Angle Mode and stabilize the aircraft. When the switch is in the middle 2nd position, Tinyhawk III will be in Horizon Mode, allowing the drone to perform acrobatics by tilting roll or pitch all the way to the end. The third position is Rate Mode which will turn off Gyro Stablization which is recommended for experienced pilots who wish to perform acrobatics and professional maneuvers.

1.Beginner Mode (Angle Mode): The maximum angle of Tinyhawk III is limited during flight to help limit speed and make flying easier. In this mode, the control of the aircraft is based on attitude. The pitch and roll input from the remote control controls the pitch and roll angle of the aircraft. For example, a 20-degree tilt of the joystick will be converted into a 20-degree tilt of the Tinyhawk III.

Intermediate mode (Horizon Mode): This mode has a higher angle limit and is used for higher speed flight with the same attitude control. The only difference is that at the end of the gimbal for pitch and roll, it will cause the aircraft to flip in that direction.
Advanced mode (Rate Mode): This mode allows you to fully control the aircraft. There are no more angle restrictions, and control is based on rate. This means that the control input from the joystick sets a rotation rate on the axis.

Straight flight

To learn how to fly Tinyhawk III, you must first fly within sight (without wearing Transporter 2 Goggles). Turn on the power of Tinyhawk III and place it in a safe and empty room. Start Tinyhawk III, then use the left stick to raise the throttle to the hovering position. First try to maintain a stable altitude, the left and right thumbs control the throttle pitch angle of the joystick, so that the Tinyhawk III can fly normally. You need to practice many times until you have reached a level of proficiency.

7.3Advanced Flight-First Person View (FPV) Flight

After you have certain basic operating skills, you can try to fly with the Transporter 2. Make sure that the Tinyhawk III and Transporter 2 goggles are on the same VTX channel, choose an open and safe place to fly, and operate according to your experience. Control the throttle to keep the aircraft level and fly slowly, which makes it easier to learn to fly FPV. When you have enough flying experience, you can control Tinyhawk III freely in the air.

The Transporter 2 screen display (OSD) image data from the Tinyhawk III camera. OSD displays important information such as flight time and battery voltage. During the flight, please always pay attention to these numbers to understand the remaining battery time. Tinyhawk III can fly up to 4 minutes. When the battery reaches 3.2v, let Tinyhawk III land. It is not recommended that the battery voltage be below 3.2v, otherwise the battery will be damaged.

Warning: Try to maintain a controllable altitude flight. Do not slam the joystick when controlling Tinyhawk III, as this will make the aircraft difficult to control; do not let the battery be lower than 3.2v; when the default AUX3 switch is set to the second position (middle), A buzzer will be activated to find Tinyhawk III.
