I dont know about unperking that thing. It may percieve to you that it is not much different than the spit9, however it is MUCH faster, accelerates MUCH faster, Climbs REALLY fast, and turns REALLY well. It is overall very manueverable. Been flying it in the CT, I am impressed with it. Those G10's, doras, dont get away from it too well. They are faster, but the acceleration of the late spit is just too much for them. Agree to lessen the cost of it (and the F4U-4).
