Ultimately I am dancing around the questions "is it fair to compare the construction of Kolb wings to Thunder Gull wings?" What did the Thunder Gull design that other ultralights don't follow suit? Not necessarily the airfoils or aerodynamics but the actual construction choices. I think I am missing the point of struts. Kolb struts run below the wing. Minimax has two that are above the wing. Thunder Gull has none. Parasols have none, or only struts, so is that a grey area? Wouldn't attaching struts at the wing tip reduce moment arms? It took me a while to digest similar posts. I didn't understand if the answer is already here. While I am a strong reader, I might be a weak thinker. Less germane to the topic: I feel silly asking but when wings are called ladder based is that just a descriptor or are we talking literal ladders?
