Hello guys. I need to help for ROS noetic to use it in Gazebo classic. I could not install the ROS to add more than one fixed wing uav. I want two uav to fly together with coordination. Can you help me? I am new to this world 
To add multiple UAVs in Gazebo with ROS Noetic, you’ll need to tweak your launch files to handle multiple vehicles. Make sure the models and world files are set up correctly, and adjust the communication and control settings for each UAV. This way, they can interact smoothly.
