Cobra Plan, RCM Aug 76
 

Here's another .40 size design that's appealing, just not sure about that flying stab. Can they be solid and reliable? I'm wondering- in general did the classic designs use a thicker wing, say 15 to 18% than the newer designs? Noticed the Option 120 published in July 07 Flying Models has only an 11% wing. I wonder if that's a modern trend and if so, for what reason.
