Rick Byrd, whom flies IMAC and this past year returned to flying AMA pattern, Masters class for his return... who also managed to win the class at the national level, was kind enough to host a day of set up, trimming and training for all Thunderbird club members interested. This was held Sunday, and could not have come at a more perfect time. I had the plane set up well, but it needed the cg moved forward, and could use more dihedral. Fortunately I was able to mix the tuck and roll out of the knife edge, and it tracked through the loop well. I still need to fine tune it, but he saved me lots of time with his exceptional experience. (I believe he started flying pattern in 1980 and won Masters in 1989.)
