I suppose you're turning her into a C? Or are you going to do the old E version?
I'm not sure what you are asking, because Cheetah C's and E's are totally different aircraft. Cheetah C's have a longer fuselage, larger canards, later model CHAFF/Flare dispensers, JM-6 ejection seat, different EW sensors, wrap-around windshield, Kfir style main undercarriage and doors, different refueling probe and an ATAR 09K50 engine, just to mention a few. This one is an E for sure. There is a conversion set for the Cheetah C from Scaleworx aswell, but this is not it.
