Methods, devices, and systems of various embodiments are disclosed for operating a UAV. Various embodiments include a UAV having a pivotal platform, a tilt assembly, and a processor. The pivotal platform may be configured to selectively tilt relative to a frame of the UAV. The tilt assembly may be configured to change a tilt angle of the pivotal platform. The processor may be coupled to the tilt assembly and configured with processor-executable instructions to determine whether to implement a first change of the tilt angle of the pivotal platform in order to causes a first adjustment of a lift/drag profile of the UAV. The processor may also be configured to activate the tilt assembly to implement the determined first change in the tilt angle of the pivotal platform in response to determining that the first change should be implemented.
