In America Pitcairns worked wonders with the autogiro and it is interesting to compare the mechanics of this American contemporary with the Cierva designs.
It is a pity that most commercial modern day autogyro designs have now been grounded by the UK authorities,the Air Command 532 series suffering from blade deflection which can literally chop off the tail by in-experienced pilots,despite modifications to try and avoid this the problem still exists.
Thankfully we still have a few people experimenting and perhaps who knows one day we will have the almost foolproof autogyro design in our skies ?
