Navodila za uporabo
1. Združevanje drona in krmilnika
- Postavite dron na ravno, ravno površino.
- Vklopite dron. Indikatorske lučke bodo utripale.
- Vklopite daljinski upravljalnik.
- Push the left joystick (throttle) all the way up, then all the way down. The drone lights will become solid, indicating successful pairing.
2 Vzlet in pristanek
- Vzlet z enim ključem: Press the one-key take-off button on the controller. The drone will automatically ascend to a stable height.
- Ročni vzlet: Push both joysticks simultaneously to the bottom-outer corners to arm the motors. Then, slowly push the left joystick (throttle) upwards to take off.
- Pristanek z enim ključem: Pritisnite gumb za pristanek z enim gumbom. Dron se bo samodejno spustil in pristal.
- Ročno pristajanje: Slowly pull the left joystick (throttle) downwards until the drone lands. Once landed, push both joysticks to the bottom-outer corners to stop the motors.
3. Način ohranjanja nadmorske višine
The X900 drone features Altitude Hold, allowing it to maintain a consistent height without continuous throttle input. Once the desired altitude is reached, release the throttle stick, and the drone will hover at that height, making it easier to control and capture stable footage.

Figure 4: Drone utilizing Altitude Hold feature.
This image depicts the SIMREX X900 drone maintaining a stable altitude above a grassy field, demonstrating its Altitude Hold capability. A dotted line indicates the drone's fixed height.
4. Način brez glave
In Headless Mode, the drone's orientation is relative to the pilot, regardless of which way the drone's front is facing. This simplifies flight control, especially for beginners, as you don't need to worry about the drone's actual heading.

Figure 5: Drone operating in Headless Mode.
This image shows the SIMREX X900 drone flying over a body of water, with arrows indicating movement directions relative to the pilot, illustrating the concept of Headless Mode where the drone's orientation does not affect control inputs.
5. 3D Flips and Stunts
To perform a 360-degree flip, fly the drone to a sufficient height (at least 3 meters). Press the 3D flip button on the controller, then push the right joystick in the desired direction (forward, backward, left, or right). The drone will perform a flip in that direction.

This image captures the SIMREX X900 drone in mid-air, depicted in various orientations as it performs a 360-degree flip, showcasing its stunt capability.
6. Način gravitacijskega senzorja
Activate Gravity Sensor Mode via the smartphone app or controller. In this mode, you can control the drone's flight by tilting your smartphone or the controller, providing an intuitive and immersive flying experience.
