Franco Bugada, e-mail, 25.09.2014 10:10 There is a mistake on the above text. The pilot who successfully transferred the biplane mode to autogyro mode was George Townson and not Townsend. It seems 100 times from the literature. A nice three view drawing of HV-2A is in the book of Bill Hannan concerning the international history of aircraft models. I am looking for the drawing of HV-1.

Franco Bugada, e-mail, 27.08.2014 08:05 I would like to have a three view drawing of HV.1 and HV-2 aircraft. Where I can find it ? Thanks
