I got the GoPro strap from Great3D, I had to use a sanding wheel on the dremel to widen the opening a little bit since the Yi lens is wider than the GoPro's but otherwise it works great. http://great3d.com/gopro-velcro-strap-camera-and-mount-not-included/

Ouch, how did the red bottom handle the mud?

They weren't too difficult to clean out, I didn't remove the bells but I rinsed them out a ton. It's been rainy the last couple days and I haven't had a chance to fly them yet. Hopefully I cleaned them out enough!

Nice setting, where is this?

It's a little park in the southern suburbs of St. Paul MN

Excellent. I'm sure it'll look great in a few weeks.

Looking better! I wish I had one these little 210s.

Little shaky but it looks pretty zippy.

Yep, it needed some PID tuning and I was banging on the sticks a bit to see what it would do. PIDs are much more locked in now, I'll have another video of the 2nd day of flying up later today or tomorrow. The RS2205s are monsters!

Awesome, were your rates too high?

They were actually a bit lower than I prefer just to be on the safe side for the maiden flight since I wasn't sure how stable the PIDs would be at speed. I had only hovered the quad for a minute or so before this to get the PIDs at a decent starting point. For this flight I was intentionally making some jerky moves to see if I could induce some oscillations.

Aha, so that was intentional. It did seem a little excessive on the jerkiness.

Thanks! The frame was surprisingly nice for the price. The edges were in good shape and needed very little filing. They do cheap out on the hardware a bit but otherwise I totally recommend it.
