I have been flying and building since 1960. Flying RC since 1973. Flew IC ducted fans exclusively from 1986 to 2004. Built and flew one of the first giant scale ducted fans (a 120" span, 53 lb A-10) flying on 2 OS91/dynamax fans.
United States, TX, Schertz
RC models (scale prop and jets as well as pattern planes) I always have at least one pattern plane in my fleet.
