Not that small... All of the horizontal baggage was just moved into vertical tiers. Perhaps this is better for the OP, but there are plenty of FPV racers out there with folding arms.
Yeah, trading stackup for footprint. A smaller footprint is better for storage, but this is worse for flying by adding another point of failure to each arm.
OP here. I actually updated the blog to add another picture of the Foldy Quad vs. H Quad at 45 degree angle[1]. At 45 degree+ it does have a nice aerodynamic advantage. Of course, even cooler would be to encase the entire midsection into a ball, it could be like a tiny Death Star quad :)
As for the additional point of failure, I do agree, in a crash, the plastic bolts holding on the arms snap, but I think that adds a little more protection to the motors, the arms, and the ESCs. I never had the screws come off mid flight. It does take longer to recover from a crash though, but plastic screws are cheep.
Love it! lol, unfortunately even though it's small and foldy, it does nothing to reduce the size of a huge taranis that you need to use to control it ;)
