Will the aircraft perform like an the aircraft you are in? Such as, same speed, etc? I've wondered about jumping into an F-15 to climb high and stalk.
You get the flight model and the load-outs, but somethings don't work, since this is a hack. For instance, carrier ops don't work well (must start out in the air) for the Hornet, but you can carry some insane number of AIM-120s. The F-22 will work as advertised, too. However, some ordnance doesn't work. You're not going to be dropping GBU-15s and using the datalink pod on the F-15E.
