    Re: EMG-5 Electric Motor Glider

    I'm a big fan of anything that attempts to advance the aviation art, and there are some pretty thought provoking ideas here. The one issue I had while reading was that is pilot position. I get the fact that it puts the pilot weight over the spar, but I know my body couldn't take that position for any length of time.

    I wish them success.

    I love the concept but it's sad to see that the marketing wasn't done to develop a reclined rather than prone position. IOW for nearly the same amount of work this aircraft could be marketable. Classic not-invented-here.

    This project is dead in the water with the lying down in the cockpit configuration. It looks terribly uncomfortable. Not only that but it doesn't look anywhere near as safe as a reclining position with a safety harness in an accident.

    I liked it until I saw the pilot prone position.

    I wonder if the elevator has enough authority over the flaps if the engines are not running?

    Seeing as how it's being marketed as a motorglider, it would be nice to see some glider performance specs, especially since it's being compared to a typical sailplane. Unless it's buried somewhere in the website and I didn't see it.

    My thoughts exactly.

    In the interests of playing Devil's Advocate, I point out that Motorcyclists and Hang Glider pilots adopt a similar position. And lying prone has the advantage of moving the head forward of the leading edge, whereas reclined moves your head behind the leading edge, restricting pilot visibility.

    I still think they need to rethink the prone position though. I see the feet are expected to operate rudder pedals. Getting the rudder pedals in a convenient location for a variety of leg lengths looks challenging!

    Except that in a prone position, it becomes more difficult to look up, which negates the advantage of being farther forward. I've flown hang gliders both prone and seated and will pick seated over prone any day.

    I agree. I only defend them because I think it is a good thing to challenge conventional thinking from time to time. Even if the conclusion we come to is that it is still a daft idea.

    Does anyone have anything to say about the rest of the project?
