Alternatively, there is the MATLAB Support Package for Ryze Tello Drones. This Support Package supports the Tello, Tello EDU, and Tello Ironman variants. These drones are manufactured by Ryze Tech and powered by Dji, which is one of the global leaders in the drone market. These drones are also relatively easy to buy from Amazon, Best Buy, or from the official Dji store.
The Ryze Tello Support Package is only for MATLAB and so to design a controller in Simulink you would need to use MATLAB Function Blocks to call the commands. However, due to hardware limitations, it is also not possible to deploy custom code to the drone and thus may not be suitable in many situations.
