I see it as a BIG advance for small drones. The same torque from smaller engine where every gram counts is a big win, you can replace that weight with more battery.
- kragen 7y agoWhat counts there is power density, not torque density, isn't it? Quadcopters don't typically gear their motors down, instead preferring to pitch the rotors at shallow angles of attack.
