[NSRCA-discussion] FrSky DIY 2.4 GHz Transmitter Module

[Ronald Van Putte]

I just received some new DIY (do it yourself) conversion packages  
which enable you to convert your 72 MHz transmitter (like that  
perfectly good Futaba 7C you have), which doesn't have a module to  
2.4 GHz and it only costs about $20.  Look at it here:  http://

The 8-channel receivers are also about $20.  Look at them here:

HobbyKing also sells some FrSky receivers with fewer than 8 channels  
and they are correspondingly smaller and lighter, but not much cheaper.

So, for under $50, your old 72 MHz transmitter can be on 2.4 GHz.

Just for grins, this afternoon I took one of the old 72 MHz Futaba  
Skysport 4 transmitters that I'd been selling as buddy boxes for $20  
and installed the FrSky 2.4Ghz DIY module.

I had to solder three wires, installed the bind circuit board with  
the LED and switch in the hole where the crystal used to plug in and,  
after removing the 72 MHz antenna, I mounted the 2.4 GHz antenna in  
its place.

BTW, the locating the soldering points for the three wires was  
simple.  You just have to look where the wires going to the buddy box  
connector are soldered and solder the wires to the corresponding  
colored wires on the buddy box connector.

It came out looking pretty good. It can even still be used it as a  
buddy box.
