Next : FUTABA 's Binding?

Will you think about binding deviation with FUTABA RXs?

I'm less optimistic about existing RF modules. Futaba seems to use customized RF chip with "Futaba" logo on it.

So it was just rebranded CC2500!
I saw exactly the same board with "Futaba" chip on it somewhere on the web. So it is

BTW, is it technically possible to make some kind of module multiplexor or all-in-one module? I think the most complex part will be antenna switch.

Herewith some background information on the Futaba Fasst protocol and the potential implementation

I would also be interested in a FASST-version. This would really make the deviation TXs' unbeatable. I don't think the protocol would be the big problem.
But where to get transmitter PCBs? Without them, you cannot do any upgrade to a devo transmitter.

Does anyone know, if there's anywhere a ML2724 transmitter PCB available???
For I really don't think it's a good idea to make such HF PCBs ourselves...

Using the Futaba TM-modules would surely be easy (you just need to feed them by PPM), but they are also costly.
But I couldn't find any cheap transmitter PCBs, like e.g. for the A7105s.

I know this is an old thread.

I looked up the ML2724 (RFMD site is a mess) The part has a 2003 date on it, lacks an integrated base-band engine, which would suggest the part has been superseded by newer and better parts. The "not recommended for new designs" stage should have passed many years ago.
There should be no reason to use this part unless you need compatibility with old equipment, which may be the case why Futaba uses it in later products.

ML2730 also lacks a baseband engine. This antiquated part (2009?) "only" contains RF-modulation and de-mod sections, and is way behind the curve of other SoC-parts that also include base-band engine, USB, SPI-interface, AES en/decryption and integrated micro-contoller and other stuff.

It does have a 20dBm PA and may well be a nice part, for its era, but any new design would clearly leave it in the dust, and I would consider more recent designs, like www.ti.com/product/cc2540 with a CC2592 25dB range extender, and others.

There is always a trade-off in pissing off old customers sitting on piles of old equipment that may become non-interoperable.

"ML2730 also lacks a base-band engine."
This may be the reason Futaba has a branded chip to interface this this part?
Alone the ML2730 can't do anything.
