This seat not only replaces the incorrect seat in the Magic Factory A-4 kit, it is also scaled to fit that kit. This particular seat features the tightly packed parachute pack. If you prefer wrinkled look at set 48287. This seat will not work in the Hasegawa family of kits as it is undersized due to the overall dimensions in the Magic Factory kit. The kits cockpit is too narrow and too short and therefore requires a whole new design for the seat. See the photo below with a PHR seat meant for Hasegawa and the Magic factory seat next to it. The Magic factory seat is quite a bit smaller.
