Battery & Charging
The E8 Transmitter is compatible with a 18650 battery, with a working voltage of 4.3V-3.3V.
When you need to reinstall the battery, remove the battery compartment cover and install
the battery according to the correct polarity (the negative pole is on the spring side of the
battery compartment). Confirm that the battery compartment cover and the battery
compartment are perfectly matched then push forward until locked. If the battery is not
installed correctly, charging and starting cannot be performed correctly.
The remote control is charged with the micro USB at the bottom. After the USB cable is

Note: It can be turned on and charged only when the battery polarity is correct, it will not
turn on or charge.
Instructor port and simulator operation
Trainer Port for Simulators
Insert one end of 3.5mm male to male into the trainer port (3.5mm audio interface), and
plug the other end into the simulator (sold separately) to output the corresponding channel
value.
Plug the micro USB cable into the remote control to output the corresponding channel
value.
5.Gimbal Trim
Each joystick has a corresponding Trim button. Each Trim button adjusts the direction of the
corresponding joystick control. Each time it is adjusted, a beep will sound. When it is
adjusted to the center position, it will make a longer beep. Please pay attention to the
sound. With joysticks centered, use the Trim buttons until the drone is steadily hovering in
place.
Calibration of joystick
The E8 Transmitter is pre-calibrated, but recalibration can help solve some common issues:
1. With the E8 Transmitter turned off, press the "L3-" button and the power button at the
same time as the controller turns on.
2. Wait for the center indicator to light up and change from fast flashing to slow flashing,
and push the joysticks of E8 Transmitter to the maximum travel in the four directions up,
down, left, and right.
3. Press the "L3-" button, the prompt will sound, exit the calibration mode, and the E8
Transmitter will then boot up.

connecting the joystick to the main board does not need to change positions).
Left-handed mode: E8 Transmitter left stick, controls the throttle and yaw direction of
Tinyhawk III; E8 Transmitter right stick, controls Tinyhawk III's pitch and roll.
Right-handed mode: E8 Transmitter left stick controls the pitch and roll of Tinyhawk III; E8
