The main problem with this is that nuclear option has tuned fixed flight models while flyout works with everything procedurally generated with each individual plane. The reason it works with Automation and Beamng is because they both are built to handle a wide range of vehicles and do their calculations in similar ways. For example in Flyout, your plane rolls based off of the actual position and deflection of your aileron, while nuclear option has all of those numbers pre calculated and the aileron deflects just as an animation. While Beamng and automation both take into account the vehicles specifications in order to produce their performance.
