This tall kit is originally supplied with a single long body tube. Since it was damaged in shipping, I cut out the crushed section and spliced together two smaller tubes by making a long, 10" payload section out of the upper third.  These tubes had to be sized exactly as the original, because the supplied full-body wrap decals needed to be used.  This kit came with a lot of high quality parts, including a foil-lined motor tube, a parachute swivel, cloth-covered shock cord, matching aqua-colored heavy plastic parachute and of course all those decals.  It takes 24mm D and E engines.  I added an ejection baffle to this rocket.
