Which runcam do you have? I've been looking at the Runcam 5. It's a GoPro session knockoff.
I increased P from 47 to 50. If I can get out and do some flying today I'll get a video. I may shoot for a 1 min video this time.Sounds like you can go up on the P a bit more.
Oh and......
WE NEED LONGER VIDEOS YOU SLACKER!!!!!!!!
