Simscape Simulation,External Force and Torque........ has its follower port rigidly connected to the world frame; it has no effect. You can configure this diagnostic in the Simscape Multibody Configuration Parameters dialog. [4 similar]

Hi I am having issues with this simulation. I have followed Ryan Gordon And Michael Carone's example to be able to simulate my own QUadrotor. I am having this issue and I am unsure over how it can be resolved. https://www.youtube.com/watch?v=fpJZSQmqDVk&t=1206s
