This is my first Binder Design rocket. It comes in a bag with 9 pages of detailed instructions. It has a standard body tube (you must cut the marked fin slots) and 3/16" plywood fins with through-the-wall (and to the motor mount) fin mounting. It uses three 1/8" centering rings. They are not plywood (Masonite?) and fit loosely on the motor tube, so I replaced them with LOC centering rings. There were no factory problems with the kit. It comes in either 38mm or 54mm versions, I opted for the latter. I'm using a SkyAngle 36" parachute. I am also using HeatShield parachute and shock cord protectors from Pratt Hobbies, and I am using 1" tubular nylon in place of the elastic shock cord. I decided to glue the nose cone to a 7" portion of the upper payload body tube to make a "scale" nose cone, and glued the lower portion of the payload body tube to the booster portion to have the rocket separate at the new nose cone/body junction instead of farther down the body. I then filled the seams with Elmer's Fill 'N' Finish.
