This KK2 board was my key to acro flying. Rate mode is amazing. And I find it pretty "forgiving" regarding vibrations. This small quad has been beaten hard. Shafts bent, arms crushed etc. Still the KK2 stabilise it very well. Video absolutely best in HD full screen. It's a small quad and a wide angle on that GoPro:
