"The Griff 300 gets its name from the number of kilos it can lift and carry. Converted to U.S. measurements, the drone can lift up to 660 pounds, including the drone's own 165-pound weight. The drone can then fly with its cargo for 45 minutes, according to Griff Aviation."
165 pound drone that can carry cargo for 45 mins??
I feel like these specs are unheard of!
I want to design a heavy lift drone that can lift 180 - 200 pounds for around 20 mins.. And hoping to keep the weight of the craft itself under 80..
