   Post on What model were the speed and aerobat wing introduced in Avidfoxflyers General Hangar

   By TSoftware, posted 5 Apr 2017

   Anyone what model the speedwing and aerobat wing were introduced.  The history that I found here doesn't mention them until model C.  I have a possible B model that appears to have an aerobat wing, it is 23'8" long and undercambered, but it has 18" ribs on it.
   TIA
