I just got a F12 myself (used) I only got a chance to fly it on the beach this weekend, as the wind was real light. But I'm damned psyched to try it when the wind picks up!
Loooooong and thin when you roll it out, but seems smooth up in the air. I need to do something about those flares, I don't like how they flop around. Maybe I'll install a leading edge batten or something to keep them under control.
You da Man, when it comes to the F, though, I watched all your vids, thanks.
