Abstract

A method for a radio control transmit controller communicating with exactly one radio control receiver is provided. Two or more identifiers are stored in a radio control transmit controller. Each identifier is an identifier of a radio control transmit controller. The transmit controller receives a link request from a first radio control receiver. The link request includes an identifier of the first receiver. The transmit controller determines if the identifier of the first receiver is in the two or more identifiers. If the identifier of the first receiver is in the two or more identifiers, the transmit controller transmits a link response to the first receiver.
