No hijack. I believe adverse yaw is one of the things you'll be dealing with.
Nickel is a math professor with an interest in flying. He was presenting birds as "tailless" aircraft and probably looking at them as gliders. I didn't quote him exactly. What he actually said is that a bird's tail was not a stabilizing instrument. I expect he'd agree with all your exceptions to that statement.
He talks about the flying plank type wing in the book. With a reflex airfoil it allows you to skip using a tail as a stabilizer. You could still have it in your model for other reasons, you just wouldn't need it to stabilize the wing.
