60th Anniversary Edition of Matt Kania's 1947 speedster originally kitted by Megow.   Perky is designed for Postal Contests where each contestant builds the same model and flies it at their home.   The flyer then submits their time for a set number of laps flown.  At the end of the year all of the times are averaged for the models flown over that year.   The person who comes closest to that average time is the winner.   Being the fastest or the slowest does not help as you need to be in the middle.   There have been two write ups in Control Line World magazine about the Perky Postal race.
