good input guys.

Just a quick question, does all 2.4ghz transmitters have a fail safe when turning on/off or loss of signal etc? Or doe sthat depend on the RX purchased?

Also I know with the 40 mhz systems you could use a futaba transmitter with jr RX as long as the crystals matched, how does this work with 2.4ghz? will any receiver work with any transmitter now?
