This is the Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System, with an included R304SB Receiver. The 4PX is the most cutting-edge 4-channel radio in the Futaba fleet. The 4PX is 30% faster and 0.5 oz. (15 g) lighter than the 4PKS-R, for ultimate response and comfort. It’s fully stocked with all the features today’s drivers want — and then some.

At the heart of the 4PX is a full-color TFT (Thin Film Transistor) display that's easy to read in any light condition. This large, 3.5" (89 mm) LCD has intuitive menus and clearly labeled graphics for hassle-free operation. Racers can even monitor lap times and battery voltage in real time without having to scroll through multiple menus.

The 4PX also includes a synthesized voice for telemetry data, so drivers can hear the latest updates through the built-in speaker or headphones (sold separately). A large, assignable button on the bottom of the transmitter lets users activate key features instantly.

Compatibility with T-FHSS, S-FHSS and FASST protocols gives drivers the freedom to use the 4PX with their favorite Futaba 2.4GHz receivers. Durable, long-lasting potentiometers result in improved, precise calibration; insert a micro memory card (sold separately) to update software and transfer models from one 4PX to another.

Other highlights include multiple crawler functions, two trigger choices and a steering wheel with drop-down option – all proven features by drivers all over the world. Of course, they only represent a small part of everything the 4PX has to offer. See the features below for a full list of what the 4PX has to offer.

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Hands down The BEST RADIO I Have EVER seen, held and now owned. It's just in a different league from anything Sanwa/Airtronics, KoPro Po or even Futaba in this case, has put out in the past.
The feel in the hand is unlike any other Radio and the fact that the receivers are only $40 per piece, this makes this one of the Best investments for your RC Arsenal.
Here's My Unboxing & Review of The 4px if you have any doubts in your mind: https://www.youtube.com/watch?v=sETLHG8pVcY

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Couldnt agree more with the other review. Great radio, very happy with it. I noticed a difference as soon as I turned it on in terms of speed which does take some getting used to initially. It also has a good weight without being too light, its easy to adjust tension on the trigger and wheel, the screen is huge and easy to read even in the sun, and all of the settings are similar to older Futaba radios but have enhanced features/options. Another great part is that it will fit in your 4pks-r cases, I had the the 4pks-r and the 4px fits great in the case so I'd assume the 4pks case will work too. I definitely recommend getting a LIFE battery because it definitely uses up more power than the older radios, my 1600mah LIFE was drained after one race day. And my favorite feature specific to nitro, the RX battery level indicator, no more guessing how much life my receiver lipo has or having to take the lid off, but I believe you need the newer receivers for this feature to work. Over all very happy with the purchase, my 4pks was on the fritz, otherwise I wouldn't have bought the 4px right away but now I am very happy I did.

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Just AWESOME !! It looks Great, Feels Great , It's nice and light, THE screen !! what can I say ITS SICK ! easy to see great colors every thing u need to know is right there on the screen . what I think about the steering and throttle feel , throttle feel was a little more touchy then my Radio-Post ts401, but is Very Smooth !,by my 3rd lap it felt good , The Steering wheel was to Stiff for me. So I used the tools that they give you to soften the feel of the wheel, after that it was great . I Believe This Is the last radio your ever going to Own ,, I don't know what else Futaba can do to make this any better? Futaba has out did them self's on this Awesome Radio ! great job to the Team who designed the 4PX !!

FYI Guys ! There are so many setting's that it's going to take me hours to Read the manual and learn all the setting on the 4px this new 4px is an all around radio , if your a hard core racer or just a Club racer that wants to take it to the next level. Also if your a Crawler or U4rc Person you will LOve there settings on here !!!, also the on road guys I feel like you will enjoys there steering settings because we all know on road guys like there steering lol

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Great radio very light and super responsive its noticeable over my 4PKS R takes a few laps to adjust to the increase in response. I modified my trigger to take a little of the gap between throttle/brake away I like to see and update there but this is definitely the best radio on the market right now.

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
awesome radio.. easy to set up lots of feature.. i recommend using a Life battery

fyi when updating the firmware on this you need a minimum of 16GB micro sd cards... if you have a android device with a micro sd card you can download it from the device and put it on the sd card and put it in the radio..

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Excellent radio in every way. I had a 3PM-X before this one, and found it cumbersome to navigate around the menus and change models. This radio has a beautiful display... the best out there currently. It makes life a lot easier when you can change settings quickly and easily. As for the performance? Well, it doesn't get any better. Also, the receivers are not that expensive at $60 each.

Futaba 4PX 4-Channel 2.4GHz T-FHSS Radio System w/R304SB Receiver
Great radio! I upgraded from an M8 with a Spektrum 2.4ghz module. Night and day difference. Lighter and way way faster. I had to re-adjust my servo horns once i plugged them in and powered up my rx. Much better resolution. Now I just need to get it dialed in the way I want.
