700 Governor gain

In my previous video of the 700 flying again, there was a strange vibration. I had heard this noise before on my friend's 450 and he was running a CC esc too. I was thinking what it could be until I realised that the governor gain was too high and was oscillating. This caused the motor to speed up and slow down really fast, which then caused the tail to wag. I had it set on medium, so I put it down to low and it's flying great again! :)
