Videos from the first flight with the Gimbal and GoPro Hero4 attached:

And here is a 360 degree rotation of it hovering on a fairly windy day:

Very stable, although adding the gimbal with the GoPro HERO4 makes it a bit front heavy; needs a re-trim when the gimbal is attached, but still very stable once this is done.

With a 3,300 mAh 4S LIPO I get between 10-12 minutes flying time.

Thanks
