Estes Pro Series II Leviathan rocket modified. Ya scallywag! On me first flight, t' rocket landed in t' parkin' lot and splintered t' tip o' a fin. Arrr! T' splinterin' was pretty deep, so I decided t' make a mod t' it. Aye aye! After simmin' t' change in Open Rocket, matey, 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 be parallel with t' aft o' t' rocket. Arrr! I decided t' look o' t' modified Leviathan was very "Patriot missile" looking, so when it came t' paintin' I tried t' mimick t' look o' t' Patriot.
