This is a scratch built, scaled down version modeled after the Binder Design Raptor. The body diameter is standard BT-60 and the overall length is about 34". The nose cone is molded plastic and the fins are 3/32" balsa. It has an ejection baffle, screw on motor retainer and 18" nylon parachute. It flies on 24mm black powder motors. I decided to do a blue to black fade on the paint, hence the rockets name.
