reduce roll when either side engines are shut off

[_LLJY]

How can i reduce the roll effect when the left side or right side engines are completely shut off? my plane goes out of control when only one engine is shut off.

 

this is a picture of my plane's engine placement.

Answer 1) don't turn them off.

Answer 2) if you insist on turning one off, then turn the opposite one off as well to balance it.

Answer 3) Raise the wings on the body, pack the engines even closer to the body to reduce torque to a minimum, and add way moar aerodynamic control surfaces to try to counteract the massive torque from an unbalanced goliath.

1) I want the plane to be as realistic as possible, therefore I need it to be able to fly with only two engines.

3) I already have a ****ton of control surfaces, they cannot control the torque from my modified goliath (400Kn of thrust for realism )

This is made worse because jet engines are much more powerful in KSP  than they are in real life.

To stop planes being too overpowered, they have reduced lift:drag ratios a lot compared with real life.

So,  you need more thrust to fly, but you have more thrust.  Which is fine until you have an engine out on one side, like you just discovered.

Also, the very powerful engines make it easier to simulate thrust reversers.   Just thrust backwards - done.

Real airplanes have lower thrust:weight ratios,  and thrust reversers don't redirect all of the airflow, nor send it straight back.

The air that does get redirected by the reverser, comes out mostly sideways and a little bit forwards.

This disrupts what is normally smooth airflow around the wing and engine to destroy lift and create huge drag.   It's like a "virtual parachute" .

They are very effective at landing speeds, but are normally turned off below 80 knots - by this point you're mainly just making noise - and trying to suck bits of gravel into the inlet.

AFAIK, the Goliath is underpowered compared to the Trent that it was modeled after
