RE: Composite-arf, Retracts for Roo?
I would agree with Bill on this one. I bought a set of Robarts for my Rookie after some advise was passed to me from some one with experience with both. I bounced the crud out of the plane before I got the hang of landing delta wing planes. Never a problem with the Robarts, not even a slight bend! Do your self a favor and save the headache.
