The Emigh Trojan A-2 was an attempt to simplify aircraft construction as much as possible--interchangable tail surfaces, external wing ribs and, notably, a completely symmetrical wing section that the left and right wing panels could be interchangable.
Presumably, a symmetrical section like that gives up quite a bit in terms of maximum lift in return for that structural simplification. Other than aerobatic types, symmetrical sections are rarely used for wings.
Are there any other non-aerobatic aircraft that use a truly symmetrical wing section?
Are there any other pros and cons to a totally symmetrical airfoil, other than, of course, suitability for inverted flight?
Cheers,
Matthew
