Falco F8 and the GeneralAvis F22 are similar and I think related (? Both Stelio Frati designs).
Indeed, both came out from Frati's pencil.... both great designs.
I saw the Furio at Oshkosh 2011 and I was in contact with G. Nustrini, but in spite of moderate running costs the a/c has a surprisingly high purchase price (more than 350.000 NZ dollars for a decently equipped one) to which transportation to Europe must be added... on top of that the a/c is still not available on second hand market (too new, of course)...
