Just some short clips I threw together showing how stable the quad and gimbal are with the Gopro 3 Black :) Only thing now is that I wish it was a 3D gimbal as left to right movements are not counter acted by the 2D gimbal. Anyway works really well for what it costs :) One other thing the vibration dampners are too soft as it sometimes wobbles in flight so will have to sort that out too.
Overall I would recommend this quad even though I got it second hand. Think I would adjust the max angle in the pitch and roll as 22 degrees sometimes has trouble flying against the wind.
Gopro was set to ProTune at 30FPS.
