Predators are discontinued, I'm sure there are some to be found but when they're gone, they're gone.
Having built both I would take a Viper over a Predator anyday.
The Dominator kit is ok but I can get heavy if you don't replace some wood- mine had some oak-like fuselage sides and very heavy wing sheeting which I replaced with lighter stock. I have a Racer ll kit coming- cant wait
