Controlling 3 drones with different input waypoints

[Pigenator]

I have three sets of waypoints that I am using with the base DSLPID controller for the craziefly model you have which individually work for the drones, but when I try to initialize at the same time, the drones struggle to follow their individual trajectories or become completely uncontrollable. fly.py serves as a good example of what I am trying to do, just with three different trajectories individually defined instead of the same one for each drone. So I guess my question is, is there a concise way of inputting the individual waypoints or, alternatively, what could be causing my error? Thanks!
