~~Jim Clem designed the Witch Hawk which was published in the September 1982 Model Aviation. Copies of the original article are available form the AMA Museum Library. Model was selected for NFFS one-design in 2017 to be flown with a non-schnuerle .19 engine. Ours came in with a flying weight of just under 18 1/2 oz. Model has a 59″ span and 500 sq. in. of wing area. After the one-design event model may be re-powered with a .19or .21 and flown in both A & B Classic.
