Wotcha Blue,

sorry I can't help as far as plans are concerned, but kits used to be available from here

Following are notes I made some time back:

Under the heading 'Shop' autogyros are not listed, but if you pump in 'Kirara' into the 'Suche' (search) box it came up with a couple of hits.

Ain't cheap.

Hope this helps.

Karl.
