I was trying for an up close roll at lower speeds. I think I lost too much speed during the roll and stalled the right wing. It probably wasn't helped by the fact that I adjusted the course a little during the roll to avoid the light pole. Of course, looking back at the video, it's clear I was nowhere near the pole. But that's easy to say after the fact. :D
The rudders still work, so at least I have that going for me. :D
