Base Kit: Kinetic 1/48 Sufa
This upgrade provides excellent cast cockpit tubs, instrument coamings, and ACES II ejection seats. Included are side controllers; the control sticks are molded into the side panels. Score high there; no disappearing act on the joystick or those throttle levers while trying to attach them to the panels. Detail is unmatched on the resin. The photoetch fret contains all the myriad little bits designed to disappear or be invisible except to specialized cameras or those with 20/05 vision.
Where this upgrade falls behind is the instrument panels; they require you to sandwich film with a photo-etch instrument panel, and paint the back of the films white to simulate instruments. In my case, this was not so good; the white does not show up well, and the level of detail is not up to par with other releases. You cannot see the instruments once you sandwich them to the PE; and there is no good way to correct this (Short of color PE, which if you know me is about the best there is out there IMHO).
