Futaba T4GRS

[Jamie B4]

Can anyone send me a link for a replacement lipo instead of batteries for the new Futaba 4GRS.

Also any ideas if or when I can get a second receiver for it?

i use one of these as a second receiver: FUTABA R204GF-E works very well and has an internal antenna. i bought it off fleebay for about £35 inc postage new.
cant help with the lipo as i stick with the aa's in mine

Don't use lipo in the Tx, use LiFE battery. This is what I use

There is an official Futaba battery but not been able to find it. Part number is in the back of the manual.

You can get the same receivers that come with the transmitter from here

I'm sure there are more options for you, but found these with a well known search engine.

FrSky TFR4 was Fasst compatible for the 3Grs, don't know if this carries over or not. The Futaba genuine receivers for the 4GRS aren't as ridiculously expensive as they were for the 3GRS so you might be as well sticking with them.

[Mr Eccleston]

4GRS is FHSS compatible, the 3GR is FASST compatible, they both require different Rx's unfortunately.

As you say, the 4GR Rx's are a lot easier on the pocket.

The hpi rf -11 reciever is s-fhss and binds up and works perfectly with the t4grs and at 24 quid is a steal

looking at the dimensions for the recommended Futaba NiMh pack at 84x43.5x17mm then the Hyperion FG305-2080-2S transmitter pack at 78x41x17mm will certainly fit and is available at £22.95 from;

On the subject of mixing Tx an Rx manufacturers I have never been personally comfortable with, the Rx supplied with the Tx does give you the full telemetry functionality, if you need it of course and is not hellishly expensive either, for once!
