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