Reason is that when I fly my models (in a very different manner compared to a military operations or commercial flights), I think very little of aerodynamics. If I think about aerodynamics when my model acts up near ground, they will be wrecked.
Ikarus, you're right of course here, when I'm flying my gliders the last thing on my mind is how the circulation on the wing is being affected by the flaps. Where I think that aerodynamics is really important is on the ground before takeoff.
I've heard of too many horror stories of pilots who overloaded their planes, or piled to much load in the tail and moved the cg too far aft, or some other stupid mistake that results in their death.
