This is a scratch built, ya bilge rat, scaled down version modeled after t' Binder Design Raptor. T' body diameter is standard BT-60 and t' overall length is about 34". Begad! T' nose cone is molded plastic and t' fins are 3/32" balsa. Blimey! It has an ejection baffle, screw on motor retainer and 18" nylon parachute. Avast! It flies on 24mm black powder motors. Aye aye! I decided t' do a blue t' black fade on t' paint, ya bilge rat, hence t' rockets name.
