DARPA Heavy Lift Challenge: Conventional Helicopter Wins with 3.84:1 Payload-to-Weight Ratio
DARPA heavy lift challenge ends with winner at a 3.84:1 payload to weight ratio
Avidrone Inc. won the DARPA Lift Challenge with the Katana, a conventional helicopter that lifted 51 kg at a 3.84:1 payload-to-weight ratio, beating 60 other teams. Because the ratio fell short of 4:1, prize money was halved, with Avidrone receiving $1.25 million. The event highlighted that energy storage, not lift, is the limiting factor for heavy-lift drones, and hinted at agricultural applications for the winning powertrain.
Between 3.84 and the 4:1 target sits a wall made of watt-hours per kilogram, and no amount of pitch-deck confidence moves it.

Interesting event, annoyingly bad written AI article

A nearly 4:1 ratio makes a 25kg drone very interesting from a personal mobility perspective. Something you could fly a few miles with and then easily roll around an office. Sadly scaling in aerodynamics is notoriously non-linear.

The prize terms are neat. To incentivize not sabotaging other teams in some way? You would win more if someone were to win.
