hello, I need help with this F-16, This is an F-16 that I do not remember where I got it, what matters is that I needed to make it more maneuverable so I put jet engines in the back and front of the plane which significantly improves the maneuverability of the plane, but in turn greatly increases the instability, Then I was wondering can you make the engines below only activate at 450km/h and at least 600m high, limiting it on that part would greatly improve stability, I will not upload this plane is only a whim of mine, I would appreciate it very much if you help me and if you can not thank you for taking the time to read anyway.

note: Handling motors only activate at 50% power
