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. Ya scallywag! T' splinterin' was pretty deep, so I decided t' make a mod t' it. Avast, me proud beauty! 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 be parallel with t' aft o' t' rocket. I decided t' look o' t' modified Leviathan was very "Patriot missile" looking, arrr, so when it came t' paintin' I tried t' mimick t' look o' t' Patriot.
