OK, not quite a mass build (thankfully!) but no sooner had I posted my intention and a picture of the design onto Facebook, a fellow PSS'er jumped in to say could I cut him a set of formers and a wing.
I will get my first one a little way into the build to iron out prototype problems first though, then cut him all the bits. The builder of said 2nd C17 - David Gilder. Nice one Dave!
