I know what you mean, i have altered my Mcgregor TX to Futaba, the receiver was gutted and a Futaba RX hidden inside!!! this was for use on some 60's models so it looked the part, modern internals with a retro outer case

Thanks Mike, just got one for my grandson to use with his tug, he's only 4 but really enjoys trying to manoeuver his barges, and getting quite good at it.
Cheers Colin.

Looks perfect Mike, no programming, uncomplicated to use for the littlun, and at that price what have you got to lose?
Don't dump the 35Meg set, you never know when you might need it!
Like me and my Sanwa 35Meg set, 30 odd years old and still works fine so I keep it as backup for my Catalina.
It's great that your getting your grandson started, we're gonna need replacements for the Old Codger Guard some time, and that includes me😉🤓 All the best, Doug 😎

Thanks a that's a great response. and probably says dump it and buy a new one, its for my 5yr old grandson and I saw this on Hobbyking, what do you think for a first beginners set?

Evenin' Mike, I like and agree with your basic attitude👍 BUT-
How's your electronics!?
Whereas it MAY be possible to obtain a 2.4Gig TX module for the Mac (but I doubt it cos it's probably too old) there's no way you can mod the RX to match. And which hopping system would you use? FAST, HOTT, AFHDS ...?
Assuming you can find an appropriate TX module you'd have to replace the RX anyway. Your best bet might be to look for a 40MHz TX module, there were a number about before the 2.4 craze started! You'd still have to replace the RX though, unless your electronics is up to a rebuild and retune! And make sure you have a match; AM, FM, PCM, PWM ??
The UHF (459MHz) sets never really got off the ground(!😲) so modules for those are probably as rare as rocking horse droppings!
Look for 40Meg bits.
Bon chance mon ami,👍 Cheers, Doug 😎

Hi there KIpper, its not always about the cost its rather about the challenge for me. I often do things that could very easily be done by purchasing the item, but for me model making is about setting a goal to be achieved - not for everyone I agree.

To be honest, when you can buy a new 2.4g 6 channel transmitter for £30-£35, even if conversion is possible, I don't think the cost & work to convert is worth the hassle.
