1. A method of adapting a radio frequency (RF) transmitter for use in controlling a radio controlled (R/C) device having an RF receiver, the method comprising:
- receiving a pulse-position modulation (PPM) signal from the RF transmitter, wherein the PPM signal is a control signal for the R/C device, the control signal having a plurality of pulses based on a first channel assignment associated with the RF transmitter;
identifying, based on the PPM signal, which pulse of the plurality of pulses of the PPM signal contains a particular active control signal;
automatically selecting a channel assignment map based on the identified pulse of the plurality of pulses of the PPM signal; and
generating, from the PPM signal, an RF communication signal compatible with a second channel assignment associated with the RF receiver for use in controlling the R/C device based on the selected channel assignment map.

10. An adaptor for a radio frequency (RF) transmitter for a radio controlled (R/C) device, the adaptor comprising:
-
a connector having an input that receives a pulse-position modulation (PPM) signal from the RF transmitter, wherein the PPM signal is a first control signal for the R/C device, the first control signal having a plurality of pulses based on a first channel assignment associated with the RF transmitter; a channel detector having an input that receives the PPM signal, the channel detector to identify a brand of the RF transmitter based on an identification of which pulse of the plurality of pulses of the PPM signal contains a particular active control signal; a channel mapper having an output that provides a second control signal by translating, based on the identified brand, between the first channel assignment associated with the RF transmitter and a second channel assignment associated with the RF receiver; and an RF modulator having RF modulation circuitry that modulates the second control signal to form an RF communication signal for use in controlling the R/C device; wherein the channel detector identifies, based on the PPM signal, which pulse of the plurality of pulses of the PPM signal contains the particular active control signal, wherein the identified pulse corresponds to the brand of the RF transmitter; wherein the channel mapper selects a channel assignment map from two or more channel assignment maps based on the identified pulse of the plurality of pulses of the PPM signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of using an adaptor for a radio frequency (RF) transmitter for a radio controlled (R/C) device, the method comprising:
-
selecting one of two or more cables based on a connector of the RF transmitter; coupling the adaptor to the RF transmitter using the selected cable; and applying power to the adaptor while holding a control element of the RF transmitter in a first particular position to provide, from the RF transmitter to the adaptor, a pulse-position modulation (PPM) signal having a particular active control signal that corresponds to the first particular position, wherein the PPM signal triggers the adaptor to automatically identify a channel assignment associated with the RF transmitter based on an identification of which pulse of a plurality of pulses of the PPM signal contains the particular active control signal, wherein the pulse identification is based on the PPM signal. - View Dependent Claims (18, 19)
