Hey Gordstar,
I thoroughly enjoyed my hours in the Airvan. The auto-land system is amazing! I used to take an extra cushion along for comfort. Yes, the ventilation could use some work. It's nothing compared to the ram air of the 206! I've never done photo opps in one, and can't really remember it being that bad in turbulence. All in all a great, simple, well thought out aircraft. All the best.
Cheers,
Greaser.
