FPV drones mix high-speed flying with speedy route modifications. A key drone configuration resolution is the propeller spin route, often called “Props In” and “Props Out.” Understanding these configurations can considerably influence your flying expertise.

What’s “Props In” and “Props Out”?

Props in (also called “commonplace” rotation): That is the extra conventional configuration the place the propellers on the entrance left and rear proper spin clockwise, and the propellers on the entrance proper and rear left spin counterclockwise. It’s the default in most flight controller software program. And since entrance props spin in the direction of the lens, it’s additionally known as “props in”.

Props out (also called “reverse” rotation): On this setup, the rotations of all of the propellers are reversed – the entrance proper and rear left propellers spin clockwise, whereas the entrance left and rear proper spin counterclockwise.

Props Out Professionals:

  1. Enhanced Management: The reverse rotation can present higher management, particularly in tight turns. The profit and impact is particularly noticeable for smaller quadcopters, like tiny whoops and different micro quads with low toque motors.
  2. Much less Obstruction: Decrease likelihood of obstruction by branches and racing gates, as it might simply bounce off obstacles in collisions.

Props Out Cons:

  1. Particles on FC/ESC stack: There’s a better likelihood of particles and filth being thrown in the direction of the FC stack
  2. Adjustment Interval: Pilots accustomed to the usual rotation could require time to adapt to the props out configuration.
