This bag set was designed specifically for the three-piece Hellcat wing, with the Center section left on the plane. It features our canvas/3/4"-thick padding/fleece sandwicha full-length, custom zipper, pockets for a small hardware box. The center panel bag is available as a special order. Email me at thintz@ctc.net for pricing of the Center Section. The outer wing bags have a parts pocket and web handles. There is a simple hook and loop strap to keep the bag in place on panels with the wing tubes. If your Hellcaat does not have the wing tubes in the outer panels we can add a hook and loop closure.
