Estes Pro Series II Leviathan rocket modified. On my first flight, the rocket landed in the parking lot and splintered the tip of a fin. The splintering was pretty deep, so I decided to make a mod to it. After simming the change in Open Rocket, I decided to go for it. The mod called for taking a cutting wheel on a dremel and removing the sweep on the trailing edge of the fins so it was parallel with the aft of the rocket. I decided the look of the modified Leviathan was very "Patriot missile" looking, so when it came to painting I tried to mimick the look of the Patriot.
