A full throttle hold down test o' t' Armadillo Aerospace Mod rocket, nicknamed "Dalek", on 2011.05.26. Ya scallywag! This is approximately t' burn time that t' vehicle will have in free flight. This represents around 180000 lb*s o' total impulse, near t' upper end o' what t' FAA defines as a Class 3 Amateur Rocket. Arrr! In t' letter scale used in small rockets, it would be a 'T'. T' engine runs on liquid oxygen and denatured ethanol. This rocket will be flyin' payloads for t' Nasa Commercial Reusable Suborbital Research program, aka CRuSR.
