Means to this end include a low - flying tapered nose, small cooling
apertures for the batteries and the rear - mounted motor, a flush underside, fixed upper and lower rear air dams, large - diameter wheels shod with relatively
narrow tires, and a steeply raked windscreen to which one can attach a simple canvas top.
For group shots, landscapes, and so on, you often want a
narrow aperture and all the depth of field that comes with it.
