Hi;Was recently reading thru some old mags and found article on Comabt meet in Europe I believe.They were using bueatiful foam warbirds with 15 engines?Are these kind of planes available somewhere?Not really into combat just keeping up is a major project but these planes were really neat and apparently durable too.They also had some real nice looking twins theywere flying.Can these kind of planes be purchased here anywhere?Showed picture of kit was all foam looked simple to build too.Thanks
