It would be interesting to see if a virtual model could be used to test the viability of the Heston design, doesn’t the ‘X-Plane’ simulator offer a chance to see if the design was capable of obtaining the world speed record all those years ago…
There must be enough data kicking around to at least build a scale RC model or a computer flight simulator available that would enable to test whether the Type 5’s flight characteristics were able to achieve its original goal… Or is this not possible?
