The 4* is an excellent aircraft, no ifs, ands or buts. If it wasn't successful, Bruce Tharpe wouldn't have built the Venture 60 kit, which is an improved version. If you've never built one, anything else is a chore. You just can't buy a better kit, or a better flyer. There is nothing wrong with a Tiger 60, or any of the Stiks. They are classic for a real good reason.
