Using a trick flight control process, a pilot may fly an aircraft while having control over two axes of orientation while the aircraft may be rotating automatically about a third axis of orientation. The pilot may continue to fly the aircraft during an automated trick rather than relinquishing control completely to the aircraft's electronics.

Controllable flight during automated tricks

The present invention provides a method for self-righting a remote controlled model vehicle. The method includes determining a current pitch angle and a current angular rocking rate of the model vehicle. The method further includes accelerating or decelerating a mass on the model vehicle based on the current pitch angle and the current angular rocking rate of the model vehicle to create a rocking motion about a first axis by the model vehicle. In addition, the method may include sensing a rotation about a second axis of the model vehicle and imparting a yaw moment to realign the model vehicle to rock about the first axis. The method may also include terminating the self-righting process when the model vehicle is upright.

Self-righting vehicle

A process for self-righting an inverted remote controlled model vehicle is provided. The process includes the method of determining a current pitch angle and a current angular rocking rate of the model vehicle and accelerating or decelerating a mass on the model vehicle based on the current pitch angle and the current angular rocking rate of the model vehicle to create a rocking motion by the model vehicle. In addition, the method also includes terminating the self-righting process when the model vehicle is upright. In which, the model vehicle body contacts the ground and provides a fulcrum for the rocking motion by the model vehicle.

An electronic system for stabilizing steering of a model vehicle may use different settings depending upon the RC model vehicle to be controlled. Different vehicles have different dynamic operation and responses and therefore may require different Electronic Steering Stability (ESS) system 'settings'. The 'settings' may be different &#x201c;gains&#x201d;, or different &#x201c;coefficients&#x201d; used with the control system algorithms. &#x201c;Settings&#x201d; may also mean that a completely different control algorithm may be used. For example, a vehicle A may be controlled adequately with a &#x201c;P&#x201d; control algorithm, while a vehicle B may require a complete &#x201c;PID&#x201d; control algorithm to be implemented.

An electronic system for stabilizing steering of a model vehicle may provide a curvature steering control of an RC vehicle. The approximate curvature control of the RC vehicle determined using error integration to achieve full steering. Application of a leaky integrator may be used to minimize steering memory. The leak factor may be based off gain scheduling of the steering input.

Steering stabilizing apparatus for a model vehicle

A realistic simulation of the dynamic sounds of a full-sized vehicle are created on a moving R/C Scale Model. A mounting apparatus supports an audio exciter in a model vehicle without any modification to the exciter. A full range of volume of sound may be produced by the exciter without limiting the range of movement of the exciter as volume is increased or decreased. The apparatus may limit the mechanical excursion of the exciter to prevent physical damage to the exciter. The present invention also provides a method and apparatus for operating the audio exciter in a model vehicle.
