The 9C Super transmitter is designated as a 9CAPS or a 9CHPS, depending on whether you get the plane or heli version respectively. There is no such thing as a 9CAFS or 9CHFS transmitter. The 9CAPS and 9CAFS designations refer only to the TX/RX packages, which include a PCM or PPM receiver respectively. Both of these packages come with a TX with the 9CAPS designation.
