Hiktec and Futaba
As I stated Hitec and Futaba are completely back wards compatible and will work with one another. Shift sequence is of no concern.
JR, Airtronics, Multiplex, Graupner are all the same shift sequence.
Futaba and HiTec are of the same shift sequence.
HiTec offers shift selectable RX's and some of the TX's are shift selectable, i.e. Prism's and I believe the Eclipse TX's. The standard HiTec offerings are Futaba compatible. The shift select RX's are offered as an alternative as well as RX's purpose built for Airtronics, JR and Futaba within the HiTec product line.
