At the Weak Signal Show in Toledo 2017, we were sitting in the lounge and I said that sounds like a fiasco. Dave Platt said; ”sounds like a good name for a model”. Subsequently a design emerged on a napkin. A few weeks later Dave finished a hand drawn plan which we converted to CAD and cut a set of laser parts for a proof–of-concept model. Later 2 prototypes were built. One for these instructions and one by Tim Miller for flight testing. Test model turned out to be typical of a Dave Platt design with great flight characteristics. The flaparons are unique in that through “transmitter mixing” they can be used as both flaps, and ailerons. Model has a 44” wing span with 340 sq. in of area, designed around a 200Watt brushless motor and a 3/2200mAh LiPo battery. Flying weight is in the range of 30oz.
