We've had quite a few nice mornings like this recently and I've been clocking up the hours on the mini talon. Having already made a 'misty morning' video not long ago, I have actually deleted a lot of footage just like this, but I thought it's a shame not to upload at least some of it. Actually what usually happens is I look at the video right after the flight, and having just spent 40 minutes looking at it through the goggles, I must be numbed to the picturesque beauty of it all, and I just delete it. But this time I kept the footage and watched it again about a week later, so I think it had more of an impact and seemed worthy of sharing.
I have also been using the RunCam 3s as both the FPV and HD recording camera and it's working out well. The only problem I struck was that it needs more than 5V input to function as AV out. If you give it 5V it thinks it's connected to a computer. Unfortunately the main webpage for the camera incorrectly lists it as only supporting up to a 3 cell battery, so I soldered up a special voltage regulator thing for 5V just to be extra safe, and then spend 30 minutes wondering why there was no AV out, when I could have just used my old plug with full 4S voltage.
The audio has been converted from stereo to mono, I just find it a bit annoying how it kinda flips from side to side otherwise. ... https://www.youtube.com/watch?v=24b54Sgxlp4
Here is the Box2D tank using fake conveyor belts, dressed up with some even more fake textures to make it look like the track is moving.
The same surface tangent speed given to the track fixtures is used to move textures around a series of spline points and turn the wheel textures at the right speed. The points along the bottom are attached to the track segment bodies, and the points along the top are attached to a 'swing bridge' type chain which is has nothing to do with movement of the tank and is only there to calculate the points for rendering. The wheels are also only for show.

I don't think there was ever any question about the durability of this frame, and flight handling (to me at least) does not seem greatly different, so the issues to look at are mostly about mounting convenience.

Both these cameras are pretty good. This is mainly a test of how they handle sudden changes in light, and how much detail they can retain in relatively dark or light areas.
Stats:
Xiaomi: h264, yuvj420p, 22116 kb/s, 59.94 fps, 723Mb
Runcam: h264, yuv420p, 30032 kb/s, 60 fps, 1021Mb
This video mixing, recompression and YouTube upload will mess with the clarity, but when watching the original files the Runcam has a slightly sharper picture (as you would expect from the file size difference), and slightly quicker response to light changes. Xiaomi seems to have more accurate color.
