Having built a Thatcher CX4 and spent time with Dave Thatcher in his workshop during the Thatcher Flyin in Pensacola i can assure people that no sophisticated equipment is required to build these brilliant aircraft . The CX5 according to the supplied materials list costs approx US$ 23,000, my CX4 in Australia complete less engine let me buy a beer short of A$10,00
