ZINGO

Tom Hutchinson  developed  the ZINGO in 1970-71   for FAI competition, and set an open class AMA record in FAI.   Design was published in the August 1972 Flying Models. Model has a 60” span and 440 sq. in wing area.  Stab has 132 s. in. for a total of 572.  1972 FAI rules requires a 26.3 oz flying weight for this size model. Therefore Tom elected to “beef-up” the structure using 1/8 balsa ribs and some spruce spars. We considered using as lighter structure for NFFS one-design then found weight saving to be less than 1 oz.  Our  1st kit built ZINGO has a respectable flying weight of  22.1 oz.
