RE: First bipe
I agree with wing incidence - especially the difference between the two wings. I just finished my second bipe and it has ailerons on both wings where my first one didn't. I am kind of anxious to see what happens there.
Note that the tail moment on a bipe is very short making the elevator and rudder very quick to respond. Ground loops are quite common as is takeoff pulling to the left. I found getting the tail up quickly was very important to get better control. And that is also a reason to land faster than a monoplane.
