One of my friends, Scott slope-soars his red tails. Sadly, he lost his red tail at the meet. Ironically, it stopped responding to him when he wasn't soaring it, but it was a magnificent soarer, we actually managed to find it the next day as it was coming in on a harris that we were flying. We called scott up and let him no, but as we were talking to him the red tail started soaring at about 2000 ft and refused to come down for anything, he never did get his red tail back. But he took it well.
