Rocket is built out o' 3.72" FWFG found on eBay.  T' tubin' is very nice, certainly on par with tubin' commonly available in t' rocketry hobby!  T' rocket uses a 3" LOC nosecone inside o' a 3D printed adapter. Motor mount is 54mm Hawk Mountain tubin' and t' fins are 1/16" G10 fiberglass.  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.
