T6A and T6B receivers are not interchangeable. “A” model receivers (R6A)
will not bind to “B” model transmitters (T6B), and “B” model receivers (R6B)
will not bind to “A” model Transmitters (T6A). HobbyKing lists their brand as V1
(“A” model), and V2 (“B” model). “A” model systems are non frequency hopping,
and “B” model systems feature advanced frequency hopping technology. The R6A
receiver uses a smaller satellite receiver, but the R6B does not.
