Abstract:
1. A radio control system for controlling a radio controlled (RC) model device comprising: an add-on transmitter module, said add-on transmitter module configured for removable coupling to a controller which includes at least one control input and said add-on transmitter module configured for removable mounting within a receptacle of said controller, said add-on transmitter module further comprises an integrated antenna coupled to said add-on transmitter module; and an add-on receiver module configured for removable coupling to said radio controlled (RC) model device, said radio controlled (RC) model device including at least one motor to allow movement of said radio controlled (RC) model device, said add-on receiver module being suitable for receiving a control instruction regarding operation of said at least one motor from said add-on transmitter module of said controller via a spread spectrum modulated digital radio frequency link, said spread spectrum modulated digital radio frequency link is suitable for back-channel transmission of data from said add-on receiver module of said radio controlled (RC) model device to said add-on transmitter module, said back-channel transmission of data includes real-time operating information regarding said radio controlled (RC) model device, wherein said add-on receiver module only recognizes signals from said add-on transmitter module, said add-on transmitter module and said add-on receiver module transmit active packets and binding packets, said binding packets include fail-safe data, said add-on receiver module is configured to reconstruct lost packets by monitoring data of a last received packet.
