Don't be too hard on the autogyro.

They are far cheaper to build and operate and less complicated than helicopters, giving LAMEs' less work to do per flying hour .

The rotor is always in autorotation, a safe mode for it to be, especially when operating near the ground.

The rotors produce no downwash, good for very low level ops over sensitive surfaces.

Unfortunately, they are still relatively under-developed machines, resulting in poor design, poor pitch stability (how the CAA ever allowed machines with no horizontal stabilisers and therefore no pitch stability is beyond my logic). Unfortunately some "modern" designs use excessively noisy, high revving insufficiently silenced engines and propellors set at too high a thrust line in order to get sufficient propellor tip to ground and airframe clearance.

A "traditional" tail wheel design, using a quiet, slow revving four stroke engine and prop would naturally have good prop tip to ground clearance and a naturally stable thrust line.

I would fly a Littlewing any day. Cierva (whose design it is based on) had it right, in many ways he was ahead of his time.
