Preferably it would come with a switch, so that trainers and students could both be in the same plane, and take turns at the controls. Or so a trainer could takeoff, then hand over control to student etc. I know its a trainer, but virtually every US fighter pilot spent time in one of these before going on to the combat birds.
P-39
The Bell P-39 Aircobra was one of the principal American fighter aircraft in service at the start of World War II. Although its mid-engine placement was innovative, the P-39 design was handicapped by the lack of an efficient turbo-supercharger, limiting it to low-altitude work, although the type was utilized with great success by the Soviet Air Force.
