When Flite Test finally released the plans for the FT Spitfire I saw this as a great opportunity for my first swoppable build and to take it in another direction.
I'm on the committee of my local Slope Soaring club "Two Oceans Slope Soarers" and we host a yearly PSS (Powered Scale Soaring) competition called the Black Eagle PSS Festival. There are four classes you can enter: Expert, Sportmans Heavy, Sportsmans Light and Combat. You can see the rules here http://www.toss.co.za/documents/PSS_Rules_2013_v15.pdf
I decided to build and enter the FT Spitfire in the combat class and slope the FT Spitfire for the first time. (Probably a world first? :))
I ended up maidening it in two ways in one day.
