Rocket is built out o' 3.72" FWFG found on eBay. Avast!  T' tubin' is very nice, ya bilge rat, certainly on par with tubin' commonly available in t' rocketry hobby!  T' rocket uses a 3" LOC nosecone inside o' a 3D printed adapter. Well, blow me down! Motor mount is 54mm Hawk Mountain tubin' and t' fins are 1/16" G10 fiberglass. Ahoy!  Recovery is either single deployment at apogee by way o' Cannonball Works RRC3 or via dual deployment out o' t' recovery bay with a cable cutter.
