Just gonna say, I'm feeling like I was right. The best performing Darpa lift drone so far is a bog standard heli. It did the full course with 110 lbs, which is the minimum to qualify for the 2.5M prize, but you can tell that heli has more to give. It's only the first day though. (Xtreme Aerial Concepts, lane 15)Can anyone explain to me why the Darpa lift challenge is a thing? I mean, 3D capable 700 series helicopter s have thrust to weight ratios of like 10 to 1. So... just use that? (or a slightly bigger one to carry the 200lbs.) Why have a competition when OTS hobbiest hardware can do the job? Also, why are quadcopters a thing? I get them for racing and stunts, but for long duration missions, aren't traditional helicopters better?
EDIT: Now it's carrying 135lbs.
EDIT 2: Now there's a second heli,(H-Squared) almost identical to the Xtreme one.... Ya.... looks like they're using the same turbine motor.
