These settings are global in that they affect all quads not just the one you have currently chosen to fly.

They are sliders that affect the aerodynamic drag acting on the frame of the quadcopter.


'Top Drag' is the aerodynamic drag of the quad in the vertical axis going through the quad top to bottom (or vice versa).

'Front Drag' is the aerodynamic drag of the quad in the horizontal axis flowing directly through the quad front to back (or vice versa).

'Side Drag' is the aerodynamic drag of the quad in the horizontal axis flowing from left to right through the quad (or vice versa).


Increasing the slider will make the apparent surface area of the quad bigger in this axis (more aerodynamic drag slowing the quad down in this axis). Reducing the slider has the opposite affect and reduces the apparent surface area of the quad in this axis.

If you want to increase the speed the quad will drop when horizontal then reducing top drag will do this (as an example). If you want to increase the quads speed when dropping nose first then decreasing front drag will achieve this.
