Dual mode FM and 2.4 GHz SS transmitter

Isn't this the announcement you've been waiting for ...

Unfortunately I was just joking. Its not available yet (as far as I know). It does seem to be the right transition strategy for many of us.

Imagine buying or upgrading a JR 9X/9303 or a Futaba 9CAP transmitter that could transmit both 2.4 Ghz and 72 MHz FM. It would just be part of the model memory programming. Select the model memory for the model you are flying and that selects FM or 2.4 GHz to match the reciever in the model. No need to replace all your receivers (or any at all) from the start.

I expect that this would push up the cost of a pure 2.4 GHz transmitter by what you can buy an FM RF module for today. There might have to be some clever work with aerial placement and you'd have to remember to extend the FM aerial when using an FM model memory.

I wonder if anyone will actually make a dual mode transmiter?

Where is the lift?

The only obvious drawback would be the need for two antennas mounted on the tx.

the transition mode is...

keep using the older 72 mhz TX(s) you have on hand for the stuff that still has 72 mhz radios installed.

Then as you buy new receivers (for replacement or for new planes)... buy the new 2.4 ghz that go with your 2.4 ghz TX.

Eventually... you'd end up with just one or two planes on 72 mhz, and be able to go ahead and replace those RX's and sell your old stuff on E-bay.
