Well we finally got some decent snow here in central pa we have about 15-20 inches but its drifting bad but anyway i was riding with a few f7s and f6s and they had nothing but trouble with the deep snow but I adjusted the tranfer rods and straps on the viper and when I cracked the gas she came up outa the snow and ran like a champ. Could not ask anything more from her!! if anything i need rid of the stock track.
