Took the ViFly R220 out the other day to see how she flies. Put a 4S on it and took off. I think I need to figure out some decent PID's for this thing because it felt really loose to me compared to my other quads. It didn't take long (about a minute and a half) for me to wreck the dang thing! The camera and the battery cage got beat up pretty good but short of that it seems okay. I can't seem to find much on PID's for this thing and I really haven't learned how to properly tune a bird yet so I'm kind of in limbo right now. I did adjust the rates but I don't know enough about the PID's to change them. Anyway, enjoy a short video of me wrecking my bird!
