BTW, Gil, are you far from Oostende? There was an aged guy there, Jos Schepers, who built interesting things (autogires) with rotors and Subaru engines. Didn't heard about him for about 5 years.
No I'm not from Oostende but it's only 100 km's from where I live.
I believe he (Jos Schepers) was involved trying to get the autogyro within the legality in Belgium.
He did most of his flying in France but I'm not very into the gyrocopter scene.
Regards,
Gilbert
