First flight of my new Aerotech HV ARCAS on an F52-5T reload left a lot to be desired. The body tubes failed to separate and the rocket came back sideways, landing on the edge of a parking lot just two feet from some nice soft grass. One fin broke and the fin can has a slight crimp. Failure to properly tape the motor in allowed the ejection gasses to vent through the rear. I have removed a layer of paper from the coupler to loosen it and now tape the engine before flight. The F52 engine is perfect for this rocket.
