Tom: the company has a conventionally powered model. Nice airplane. Saw an add a while back where they cut power over the Alps and it is quite the glider too. I'll take one if they want a pilot to fly them about for advertisement.They were really talking about 45 minute duration, -takeoff and -landing (pattern), that doesn't leave much time in the air. I'm surprised no one's worked out a generator/battery hybrid to extend that time. It looks like it was designed in part to eliminate as much drag as posible. Thanks for posting this.
