RE: Is this too much of an angle?
Pete,
What's the thin CA for? Anyway, if for any reason, you're unable to eliminate all of the play/slop, bear this in mind: Those stabs are designed to be dynamically stabilized, and they are. I'm sure that I've had this airplane as fast as anyone ever has, and the stabs are rock-solid throughout. On mine, I tolerate as much as 1/8" at the L.E. without any concern.
Tom.
Thanks!
