Radio & Receiver compatability q's?
1) The Transmitter and Receiver MUST be on the same frequency (27mhz, 75 mhz, etc) and the same channel #
2) The "Shift" of the system MUST match. (i.e. Both TX & RX, must be either positive or negative shift.)
Hitec has a new RX that has "auto shift" and will change "shift" based on what TX is being used.
3) In general with 27mhz, crystal brand does not matter.
For 75 mhz, the crystals usually must be of the same brand as the Transmitter.
There are some instances where the RX and crystal brand must match (consult the Radio manufacturers site for more specific details).
