is low.
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 the 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.

direction of Tinyhawk III; E8 Transmitter right stick, controls Tinyhawk III’s
pitch and roll. Right-handed model: E8 Transmitter left stick controls the
pitch and roll of Tinyhawk III; E8 Transmitter right stick controls the
