For this prototype which he built at Madrid, La Cierva used the fuselage of a Deperdussin, a French monoplane of pre-World War I vintage, on which were mounted two contra-rotating four-bladed rotors. The C.1 had a vertical surface above the rotor to give lateral control. This model never flew, since it proved impossible to control: the lift from the two rotors was unbalanced because of mutual interference.

It is because Cierva got all his money from the Weir family. Weir were the shareholders of the Cierva patents and Juan de la Cierva's backers.Thats why some of the designs are called Cierva "W." In fact its not Great Britain but Scotland!
Its Spain... there is no doubt about it

Hello, I have a doubt about the country of all the models Cierva. If the country of its designer, its financing and where the autogyros were constructed was Spain, why did you put tehm in the list of Great Britain autogyros?
Thanks for your great work and for solve my doubt
Do you have any comments concerning this aircraft ?
