Transplanting the Futaba Navy twin stick into a modern radio?

Hello,
I happen to have an old radio with a Futaba Navy Twin Stick - it's like this http://www.conrad.com/ce/en/product/...WIN-STICK-F-14
For my needs (controlling boats and steam locomotives it seems very useful).
I have almost no idea about electronics, so please bear with me.

I'd like to know if there is any modern 2,4 GHz radio which could have the twin stick installed into, that is, it should be compatible electronically with the Futaba twin stick. I don't mind doing some alterations on the radio's case myself to make it fit.

I can do what you want to achieve but I can not provide details as I would normally figure those out during the conversion process.

You can check my blog on conversions I've done.

I think this address your problem, it can be adapted to other radios or your present radio can be converted to 2.4 Ghz with a DIY module(or even just accept a regular plug-in module). ivanc does makes nice conversions for almost any transmitter!

In case anybody is interested, I have successfully converted my Futaba FC 16 to 2,4 GHz, with the ability to use 40 MHz as well with the flick of a switch. I have used the rather inexpensive FrSky DHT 8 channel receiver.

Installing it wasn't too difficult but of course involved a bit of soldering. The DHT module has enough room between the gimbals.

The white panels seen below are just home-made covers for the unused switch holes of the transmitter case. I know they might not appeal to many but my idea was to be able to easily label the switches with a marker on the white surface (which I didn't do yet).

I have added switches for all previously unoccupied channels. Two proportional on the left hand white panel and two 3-way switches on the 2 white panels in the middle.

The right hand panel is dedicated to the DHT module. The switch between the old (silver) antenna and the new (black) one is used to switch between 40 MHz and 2,4 GHz. Made it point to either antenna, so using it should be self-explanatory. The switch to the right changes between 1 and 2 way (telemetry) communication modes, with the 3rd position being for firmware update. The small black push button is used for binding to the receiver, to its left is the led showing module status.

Here are before and after pics:

That's actually the old battery pack (about 10 years?) and not holding much of a charge. A few days ago I have bought a new similar one but with only 2400 mAh.

Nimh are less durable than the old Ni-Cad, was using them in fast electric before Lipo came out and they just lasted two season!

What would be a better, more durable option for my transmitter battery?

A 3s Li-Fe would be same voltage as 8 Nicad, but they requires a specific charger!
