Hah yah I'll upload another sometime later this week of other clips from flying around there. Have one clip where I had a switch flipped that I shouldn't have and was stuck in angle mode then I hit disarm by accident instead of flipping into air mode and ended up caught by a tree/bush about 3 inches above the water. Does definitely add an element of danger for the quad into the mix.
The wifi module isn't necessary really and I barely ever use it but it is nice to be able to modify the camera settings without hooking it up to a computer. To get the wifi module to work I have to disable cell data on my phone due to some bug. Also certain settings (PAL vs NTSC and frame rate) can effect the latency so if you decide to go with it would search about that issue to see what the right setting is to reduce that latency to something flyable, after making the adjustment I don't really notice the latency but it was pretty bad out of the box.
