System, transmitting device, receiving device, and method for the wireless control of an RC model

A system for the wireless control of a radio controlled (RC) model, the system comprising:

• a transmitting device separate from the RC model comprising a first transmitter configured to transmit first information via digital radio communication to the RC model, a second receiver adapted to receive second information via digital radio communication from the RC model, and a user interface for manipulation by a user to generate control command signals for operation of
• the RC model;
• the RC model, comprising:
• a multifunctional device comprising or connected to one or more electronic accessory modules and having access to a memory located on the RC model for storing data values;
• and
• a receiver module connected to or integrated with the multifunctional device, the receiver module comprising a first receiver configured to receive the first information and a second transmitter configured to transmit the second information;
• wherein said first transmitter is configured to transmit in a single transmission first information comprising one or more protected data packets and one or more non-protected data packets:
• said one or more non-protected data packets configured for a unidirectional control protocol and containing said control command signals, and
• said one or more protected data packets configured for a bidirectional control protocol and containing (i) data for parameterizing the multifunctional device or the one or more electronic accessory modules, and (ii) information relating to a data-protection protocol, and
• wherein the second transmitter is configured to transmit second information comprising both (i) immediate feedback corresponding to any changes in the data for parameterizing the multifunctional device or accessory modules received from the first transmitter in a first transmission, and (ii) data corresponding to the data values stored in the memory.
