It looks like it should be a good FPV plane, and watching the 4s video it looks like it can take quite a bit more stress than the Explorer. I always fly the Explorer as a scale GA airplane, for fear of folding it up. I might build one of these for the next step in my FPV career and start flying more aggressively.
Speaking of the video,
@AircPirateNinsei is that an earth-bermed metal Quonset hut beside your airstrip? I've heard it can be done, but there aren't many out there.
