Only one place to go down here...
Call Luis Rollan at Intercopters +34 607 325 386 (
www.intercopters.com)
He's at Cuatro Vientos (Four Winds) airport, Madrid, and tell him Dan Coughlan sent you.
Luis has a couple of R22's and a R44 available, I think. He'll sort you out. He's also the Robinson importer/maintainer, so you should find all you need.
Let me know if you're flying down south; Malaga, Granada, etc, and I'll show you where all the good bars are, too.
Good luck
Dan
