    Really? That's 300g/dm2. And I have concerns about 90g/dm2 on my uav project....

    That's nothing - I've flown over 100oz/sq. ft.

    380cm wing span and 38Kg MTOW? If I assume a mean root chord of 50cm then I have a wing load of about 200g/dm2. Isn't that a bit too much or I'm missing something? This plane should come down like a stone...
