Here at my place you should not have problems with N registered aircraft, also maintenance for Robbies is available - under EASA regulations, of course. Generally, Europe is considerably more expensive aviationwise compared to USA (fuel, etc.) but there are huge differences between countries/regions. If you are looking for diverse landscape and good cuisine and wines, maybe you shall come overe here to Slovenia - from 9000ft Alpine peaks to warm Adriatic sea you will fly in about 40 minutes
. Croatian coast with thousand islands is nearby, and Venice is also not far. Six months ago, an American, Eric Raymond, that built his own sucessful solar powered plane Sunseeker II, was here and he returned in May and extended his stay. You might also want to check with Woman Soaring Pilots Association, (WSPA) that held their annual conference here in May - first time ever outside USA.
If you are interested more, PM me.
