AF.... was that one of the Jodels from the Megeve Aeroclub? I did a flight from there in one with one of the locals last year and had a great time. I'm in the area a fair amount (used to live near Geneva and still have an appartment there (Grand Bornand)). I keep meaning to do the site authorisation at Megeve but have not got round to it so far. If that is where you are flying from I'd be interested in "picking your brains" via email to get some info.
