Title: Futaba Tx Question
Post by: mick on February 10, 2012, 07:09:22 pm

Hello Chaps, and chapesses, I have a 27 meg Futaba Attack 4WD radio. I do not have a manual with this radio.
I am presently using eight dry cell batteries in the Tx.
I am looking to upgrade the Tx to be able to use rechargeable batteries. There is a charging socket/jack already installed on the side of the radio.

I want to replace the dry cells with rechargeables.
Can I fit eight single cell rechargeable batteries, ( there does not appear to be enough room for a battery pack ) in place of the dry cells....and use the charging socket/jack to charge these batteries.

I did not want to start 'going' into the back of the Tx, unless it was absolutely necesserary.
I know I can simply 'suck it and see' , I would rather know, before I screw the back off the Tx.

Best wishes...Mick

I use eight rechargeables in mine with no bother, I do however take them out and charge in a separate charger.

Hello DickyD, thank you for your reply, I know what you mean, I do have a small wall charger which takes four rechargable batteries.
I could use that. It will take longer to charge the eight cells...however the result is the same.

Thank you again, regards Mick :-))

I highly recommend Sanyo Eneloop batteries. these are NiMH batteries with very low self discharge characteristics. In a nutshell you charge them up, and they hold their charge for months on end- they behave just like dry cells.

Sanyo Eneloop batteries are very good, however they are a lot more expensive than Vapex “Instant” AA 2500mAh NiMH rechargeable which are very near as good and can be

obtained from  component-shop.co.uk who are an excellent supplier, efficient, fast, cheap and cheap P&P

Fair enough. There are the pattern batteries too. I only paid a fiver for the pack of four Sanyos, so was happy with the price.

My old Futaba radio had dry cell batteries which I changed for rechargeable ones then left them in the radio and charged through the socket provided I had no problems with either radio or the charger which I used. (currently now charging my new Futaba radio)

Hello catengineman, this is the reply I was hoping for...I will give it a go and install my rechargables.
If nothing happens, I can charge these batteries in my wall charger.

Thanks again lads....Mick

I only got a new Futaba because the old one ran out of channels and the new one is an FX18 with 32 (I think now) though I have just ordered a different module because the one I have in it at the moment only gives me switched options and not proportional ones.

But as I said I had no problems with the old set and the rechargeable batteries
