Futabs FP T6NFK new in box
 
A guy I work with told me he had bought this particular radio new 15 years ago and never got around to using it. It's been in his closet the whole time. He's going to bring it to me tomorrow to see about trying to power it up. I doubt the batteries will do anything but what the heck. He's wondering how much he could get for the radio. I will try to get some pics up for it soon if anybody wishes to put their .02 cents in. It's a Futaba radio. I spelled it wrong in the subject line.

Gold sticker still in place.

Just about can't give away 72 mhz any more...

The servos will still be useful.

There's a few on here that still use 72Mhz ...........

If my 35Mhz JR still worked - I'd be more than happy using it ...

The batteries probably won't hold a charge since they're nicads and have been sitting for so long. The radio and receiver should be fine. They've never been used. Heck I may buy it from him for that reason alone and replace the batteries.

Talk to Chellie ... she still uses FM ....

Hi David :ws: you can buy a battery holder and buy some 1000 mah AA nicad batteries to power up your transmitter with, thats what i do with my JR transmitters. Hope that helps, Chellie

or you can buy a transmitter lipo battery from Hobby king

How would you get the 9.6 volts needed for the Tx and it fit inside the radio with LiPo batteries without going to higher voltage. Right?? Same for the recevier, it needs 4.8 volts and you won't get that without going to a higher voltage and including a voltage regulator. That's an extra step I wouldn't want to have to do. Am I off the mark on this??

The Futaba TXs from when that was made can handle 8 X alkaline AA cells for 12.0 nominal... I forget the full charge voltage for Alkalines. I remember checking with Futaba tech support about using Alkalines for their FM 72 mhz transmitters.

So according to that tech the extra volts won't harm the Tx? Interesting. I know this radio is old but its never been used. It was stored for years with the battery in the Tx. Some kind of funk that looks like green corrosion made its way into the connector that feeds power to the Tx. No gook is leaking from the Tx battery that I can tell. It's strange. I guess I feel sorry for this thing.

fhhuber 06-06-2014 02:22 AM

There's a failure called "black wire disease" which may have happened to that radio from your description. You need to see how far the corrosion has crept into the TX and you will probably need to replace any wires between the circuit board and the battery at a minimum.

Its possible for this corrosion to have eaten into the main circuit board too.

Had this happen on an old boat I use to float......but never seen it again on any thing related to a re-chargable nickel metal hydride battery....

Original battery in that old Futaba is NiCd.

Yep they are NiCads. If there is corrosion in the circuit board from them the thing is probably toast.

Check out www.barbadosrc.org/misc/blackwire.php for some good info on black wire disease
