Estes Pro Series II Leviathan rocket modified. On me first flight, t' rocket landed in t' parkin' lot and splintered t' tip o' a fin. T' splinterin' was pretty deep, so I decided t' make a mod t' it. Arrr! After simmin' t' change in Open Rocket, I decided t' go for it. T' mod called for takin' a cuttin' wheel on a dremel and removin' t' sweep on t' trailin' edge o' t' fins so it was parallel with t' aft o' t' rocket. I decided t' look o' t' modified Leviathan be very "Patriot missile" looking, so when it came t' paintin' I tried t' mimick t' look o' t' Patriot.
