- لاهڻ: After binding, press the One-Key Takeoff button. The helicopter will automatically ascend to a stable hovering altitude. Alternatively, slowly push the left stick (throttle) upwards to manually take off.
- اترڻ: Press the One-Key Landing button. The helicopter will automatically descend and land. Alternatively, slowly pull the left stick (throttle) downwards to manually land.
- اوچائي رکو: The helicopter will maintain its current altitude automatically once the throttle stick is released to the middle position, thanks to the barometric altitude holding feature.
- هدايتي ڪنٽرول: Use the right stick to move the helicopter forward, backward, left, and right. Use the left stick to rotate the helicopter left or right (yaw).
6.3 ترقي يافته خاصيتون
- آپٽيڪل فلو پوزيشننگ: This feature provides enhanced stability and precise hovering, especially useful in indoor environments. It is typically enabled by default.
