Eli5: what are the benefits of a normal helicopter design vs a quadcopter we see on drones?
In: 210
Stability, power, and control from what I’m remembering. More props means more lift so it could support more weight. That being said, you would also decrease the battery life of the drone because its using more juice to power the additional motors. You can add more batteries but that then increases the overall weight so it’s a balancing act to get to the optimal design. I designed an 8 prop drone a few years ago for a school project and this was one of the things that we ran into. Basically, you need to define the use case for the drone…do you need more lift without as much flight time or more flight time sacrificing the amout of weight it can carry.
For control and stability, the 2 additional props give you 2 more axis(I think) for stabilizing the drone and movement. Essentially it’s more like using a joystick in place of wasd on a keyboard.
