An historical note on use of spoilers...
Any decent model of the Northrop P-61 will have the spoilers this plane had.
Top and bottom.
In flight testing, the airplane was lost, and the pilot almost killed.
No spoilers were ever used on the P-61 after that; although they were installed, they were disabled.
On the short version of the Tristar, the -500, the plane demonstrated a tendency to tighten a turn. Without the use of spoilers this rapidly became an uncontrollable situation! I've seen the pilot with the column hard against the instrument panel, and the turn -still- tightening.
Pulling the spoilers slowed the plane and pitched it up. The CAA made a mod to the autopilot that -automatically- extended the spoilers on CAA certified planes above about .86 Mach.
