1. A method for controlling a model airplane comprising:
(a) the model airplane comprising a fuselage, an engine, and flight control means comprising wings and control flaps and optionally engine speed; (b) structural flight control means comprising mechanical sections and connections to control engine speed or variable positions of flight control means to result in taking off, stable flight and landing of the model airplane; (c) a control device comprising a processing device operating under a control program, where operation of the control program causes structural flight control means to effect flight control changes for the model airplane by changes in the flight control means; (d) a wireless remote controller is operated by a user to transmit wireless flight control signals received by the processing device to cause the control program to maintain or change flight control means for take off, flight and landing; (e) periodically sensing of a current altitude of the model airplane by way of an altitude sensor and transmitting the current altitude to the processing device, where the current altitude is compared to a stored control altitude value; and (f) a protection mode of the control program operates if the current altitude is control signals from causing travel or operation of flight control means to exceed predetermined limits. |
