Strange helicopter at Redhill?
Can anyone help with a half remembered trip to Redhill last century?
There was a hangar in front of which was parked a small helicopter. It was remarkable as it was small, painted all white and had a tall mast with what appeared to be contra rotating blades one set above the other.
The name over the door was (I think) Rotortech or similar.
Any clues as to what I saw and where it is now?
Many thanks, Sir George Cayley
