Under construction by Bucky Walter is this Dragonfly designed by Bob Lee and Tex Newman back in 1974. Northrop Plan Service claims this is one of their best sellers. Being published in the the defunct Model Builder Magazine twice helped. Originally powered by an O.S. .10 and similar engines, the original used a Kraft brick.
With a new Spektrum 5 channel and a PAW .09, the performance of this 728 sq. in. model should be an improvement over the original.
