RE: 2004 IMAC Sequences
I would echo Mark's comments about the tailslide. There is a great deal of luck involved with this maneuver. Moreso if the wind is blowing. I would also like to see them removed from IMAC competition as it truly does take away from the skill aspects. There is also a great deal of arbitrary application of the 'visible slide' judging criteria.
A couple comments though. The tailslide has been removed from the known in IAC and CIVA contests due to the Q not being a scored flight for contest results. The Q only serves to validate competency in the class being flown. They still show up in unknowns, and are a requirement in the free program. Regardless, they are still a much hated maneuver in full scale competition as a result of the luck factor. Matt Chapman lost the free program at the WAC in Oklahoma after his airplane slid backwards some 150' or more only to flop the wrong way.
As far as how we fly or what control inputs are required.. it's irrelevant. I don't care if you need full down, full right aileron, and wag the rudder like a fish to make your airplane snap roll.. If it looks like a good snap.. it gets scored like a good snap. If your airplane shows all the criteria for a snap roll.. then you get scored as such.
