The signal of an infrared remote control typically reaches a range of about 30 feet (9 meters) in a direct line of sight. However, this range can vary depending on the strength of the remote control and any obstructions between the remote and the device being controlled. Infrared signals do not pass through walls or other solid objects, so the range may be limited in certain situations. **

No, the remote app typically requires a physical remote control to be set up initially. The remote control is needed to pair the app with the device it will be controlling. Once the app is successfully paired with the device, the remote control may not be needed for regular use, but it is usually necessary for the initial setup process. **

The Carrera RC Quadcopter can fly up to approximately 100 meters away from the remote control. This allows for a decent range of flight and maneuverability, making it suitable for outdoor use and aerial photography. The remote control uses 2.4 GHz technology to ensure a stable and reliable connection with the quadcopter during flight. **
