Safety is paramount when handling drones, especially drones in the classroom. Ensure all safety equipment is used and in place before operating any drone.
Necessary Equipment:
- FPV Goggles or safety glasses
- Safety signage
- Rocket Drones Stage I Drone
- Rocket Drones Rover Controller
- Battery and tester
Safety Checks and Drone Inspection:
Drones should only be flown in designated flight areas. Safety signage or barriers should be used to ensure the area remains clear. Never fly drones near other people or out of designated flight areas. Inspect drone, propellers, motors and connections for any damage and ensure motors spin freely. Inspect the frame for any cracks and missing screws.
Inspect and verify battery voltage:
Fully charged batteries should read between 4.20v to 4.25v.
Wearing Safety Glasses:
Always wear safety goggles when operating the drone to protect your eyes from any potential harm. Ensure loose clothing or long hair is secured to prevent entanglement with properllers.
Always follow preflight checklists and safety guidleines put into place by Rocket Drones and your local school administration.

Step 2: Connecting The Launch Controller and The drone
Launch Controller
- Take out the launch controller and set the throttle joystick and two switches “SB” and “SC” on the top to the lowest position while ensuring that switches “SA” and “SD” are in the pop out position.
- Hold the “Power” button on the launch controller for 5 seconds until it beeps three times, and then release it.
- When the launch controller’s power indicator turns from flash red to solid blue, it means it has been successfully powered on.
A red light indicator on the controller means the left joystick (Throttle) is not in the lowest position.
Install Battery
- Install a battery into the battery mounting slot under the drone until fully seated.
- Connect the drone to the battery, and then place the drone on a horizontal surface. Wait 3-5 seconds until its status LED lights change from flashing blue to solid blue. This indicates that the initialization of the drone is completed and the drone is connected successfully with the launch controller.
If the lights continue to blink yellow, following the binding procedure foundhere.
Arming Motors
- Press switch “SA” to arm the drone.
- The throttle joystick must be at the lowest position or the drone will not be armed. After being armed, the motors will spin slowly.
- Press the “SA” switch again to disarm the drone and motors.
- Complete the above three steps to ensure that the drone and the launch controller can work normally. Then, the following flight operations can be continued.
Rogue Drone
- Important: For operating the drone, first re-arm it by following “Arming Motors”.
In the event of a rogue drone or unresponsive throttle, remember to disarm motors and let the drone fall to the ground.
Step 3: Basic Flight control
Once the drone is re-armed, the motors of the drones will start to spin at a low speed.
ImportantFor operating the drone, first re-arm it by following “Step 2”.
Throttle (left) Joystick
- In normal mode, you will need to slowly raise the left joy stick slightly above the half way position before the drone will begin to hover. Use this joystick to control the altutude of the drone. During flight maneuvers ensure you are at least at shoulder height before performing any activities.
- Left or Right movement of the left joystick controls the counterclockwise or clockwise rotation of the drone. Forward orientation is indicated by the direction the camera is facing.
Direction (right) Joystick
- Up or down movement of the right joystick controls the forward or backward movement of the drone.
- Left or right movement of the right joystick controls the left or right movement of the drone.
Before flying with goggles, it is recommended to practice and get familiar with the sensitivity of joysticks by following the above-mentioned operation steps.
- Find a suitable open place for the first flight.
- Give a slow push to the joysticks, especially the throttle joystick.
- If the drone becomes out of control or collides with objects, press switch “SA” immediately to disarm, and motors will stop spinning.
Land Drone
- Land the drone steadily and press switch “SA” to make it push up, which is shown below:
Disconnect Batteries
- Disconnect the batteries from the drone by removing them from the mounting slot.
- Hold the “Power” button on the launch controller, it will power off after three beeps.

First Person View (FPV)
First-person view (FPV) is to operate the drone through the real-time image transmitted by the FPV goggles camera. Operations for setting up goggles are given below:
- Take out the goggles and install the antenna.
- Press and hold the power button for 2-3 seconds. The screen will light up and the FPV goggles will be powered up.
- Long press the channel select button for 2-3 seconds, repeat this step until the red light on the antenna appears. Short press the channel select button to switch between FPV channels.

On-Screen Display (OSD)
After adjusting the channels, the flight information and FPV camera images will be shown on the display. This information is called On Screen Display (OSD), which is shown below:
- Flight Status: It is displayed in the center.
- DISARM: It indicates locked status.
- TURTLE: It indicates that the Turtle Mode is activated.
- LOW VOL: It indicates that the battery voltage of the drone is low.
- RX LOSS: It indicates that the drone has been disconnected from the Launch Controller.
- Status Of the Drone: It is displayed at the bottom of the screen, including the receiver protocol, drone battery voltage, flight time, flight mode, and speed threshold.
About OSD information:
For drone FPV channel controls, watch our support video foundhere.
Flight Mode
The flight mode is displayed in the lower right corner of the flight screen, corresponding to the flight mode of the drone. The pilot can choose different flight modes according to different flight environments and their flight control skills.
Note: The flight modes are selected by a switch on the launch controller.
Normal Mode
- For ascending the drone, position the joysticks of the launch controller in the center at the same time this will maintain the drone at a fixed point in a horizontal attitude.
- For controlling the direction and tilt angle of the drone, control the position of the direction joystick.
- The drone has an auxiliary flight function that can assist in adjusting the altitude and horizontal position, which makes it easier for the pilot to control.
Sport Mode
- For ascending the drone, the throttle joystick will be operated to control and adjust the altitude of the drone.
- For controlling the direction and tilt angle of the drone, control the position of the direction joysticks.
- When the direction of the joystick is moved back to the center, the drone will return to a horizontal attitude.
- When in this mode, some sensors are turned off, which makes the operation more difficult for the pilot.
Manual Mode (Experience pilots only, may cause damage to drones) Mode
- For ascending the drone, the throttle joystick will be operated to control and adjust the altitude of the drone.
- For controlling the roll direction and speed of the drone, control the position of the direction joysticks.
- The drone will maintain its current attitude when the direction joystick is moved to the center.
- When in this mode, all sensors are turned off, which makes the operation very difficult for the pilot.
Turtle Mode
- For ascending the drone, the throttle joystick will be operated to control and adjust the altitude of the drone.
- For controlling the roll direction and speed of the drone, control the position of the direction joysticks.
- The drone will maintain its current attitude when the direction joystick is moved to the center.
- When in this mode, all sensors are turned off, which makes the operation very difficult for the pilot.
If the drone crashes into the ground and the fuselage is flipped, the “Turtle” mode can be activated to reverse the motor and turn the drone back over. “TURTLE” is displayed in the center of the OSD.

Clean Battery Connectors: Keep the battery connectors clean. Use a dry cloth to wipe them before use. Dirty connectors can cause energy loss and difficulty in charging.
Safe Disposal:
Improper disposal of batteries can be a fire hazard. To safely dispose of a battery, follow these steps:
- Fully discharge the battery before disposal by flying battery to exhaustion.
- Use tape to cover the battery output connector to prevent accidental short circuits.
- Always check and follow local regulations for proper battery disposal or recycling.
Additional Precautions for Battery Use and Charging :
- Do not immerse the battery in water. Store it in a dry area if not used for an extended period.
- Keep batteries away from children. Swallowed batteries require immediate medical attention.
- Do not use or store batteries near heat sources, microwave ovens, or open flames.
- Only use a charger that meets the battery's specifications when charging.
- Never throw a battery into a fire or heat it.
- Avoid using or storing batteries in extremely hot environments, such as in cars under direct sunlight or hot weather, as this can affect battery performance and lifespan.
