Ive recently been given a mark 1 4.5m Ozone Lil' devil, closed cells with 4 vented entry points on the leading edge, so i guess its an early one cos all other lil' devils ive seen are all open vented.
anyone out there know wether they like a bit of brake bias or flown powered up? just shortened the 30m lines it came with to 25m turns a lot better now mainly for buggy use
