This is the Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System; the first Futaba surface system with telemetry! Built on the success of the first radio ever to win the coveted "Basher-approved" award from BigSquidRC.com, the 4PLS adds the ability to read and display four critical racing data as you drive.

Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System w/R304SB Receiver
I upgraded from a 3PL to this buying from a friend. If you have large fingers like me, go with the 3PL. I had to widen the trigger, well, ok, I broke it in two. But when I tire-glued it back together, I made it as open as the 3PL trigger (not interchangeable according to Futaba tech support). I then dremel'd the trigger stop to restore most of the reverse swing (overall I'm still missing 25% of reverse travel). I'm giving it only four stars for lack of out-of-the-box comfort and the learning curve. I also would have preferred an internal antenna like the 3PL as well.

Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System w/R304SB Receiver
Been using Futaba for over 20 years on everything from airplanes, helis, to cars. No one can argue they are the leader in solid link reliability. I was heavily debating on picking up the 4PX, but because of the extreme cost when it was still $550, I ended up opting for the PLS due to the fact it had most all of the programming available as the more expensive unit for less than half the cost. (Pros) Futaba undeniable link reliability It has just about every programming option you can imagine for tuning adjust-ability. The screen is very sharp, back-lit very well, easy to navigate and set Transmitter is moderately light and comfortable. Batteries last a long time Very affordable receivers (Cons) Feels a bit cheap in comparison to more expensive transmitters *(this is where the price point comes into play) Lack of a few physical trigger adjustments. *(You can change tension, over-all pull length and brake end point) All and all, this is a very good system you'll be hard pressed to match elsewhere for the money. The only other unit I would even consider within this class range is the $90 more expensive Airtronics MT-4S for it's superior physical feel and slightly less latency factor. Either way you won't go wrong with this radio for the money.

Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System w/R304SB Receiver
Bought my first Futaba in 1989 it was a Magnum Jr for my Bolink Eliminator. Futaba it just the best. I never worry about my radio. Now that I have 4pls with a life battery, it stays charged forever. Menu is easy, has a comfortable weight and feel. Best radio in its class... NO SPECTRUM GLITCHES!!!!!!

Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System w/R304SB Receiver
I have used the 4pls for a year and a half on 7 different rc cars and trucks anything from 1/10 scale buggies ,2wd short course , 4wd short course , rock crawlers , 1/8 scale buggies and as small as a 1/16 scale revo vxl and summit vxl ! It does almost everything radio costing twice as much . it has all the adjustments I need for racing and bashing or crawling And it tough as nails I have dropped it on concrete and on the ground several times and still works flawless everyone I let use it wants it or one like it. if I sold it I would buy another one like it ! It is comfortable in my hand and is better looking than most of the high dollar radios ! I'm a racer first and a basher second and this radio has made me a better driver because of all its adjustment I can dial in whatever I'm driving to the track conditions or whatever i I'm driving on. I LOVE IT !!!

Futaba 4PLS 4-Channel 2.4GHz T-FHSS Telemetry Radio System w/R304SB Receiver
I am 5'11" and weight 330lbs. The US army might say I am too big around for my height. Anyway, my fingers fit fine. The range is second to none. I had a receiver antenna pull out of one of my SB304 receivers and it still works perfect on the largest track I have ever raced. You can link 40 trucks to it, keep lap times with the push of your middle figure and adjust your car every bit as much as you can with the more expensive radio. That being said, if you plan to invest $30,000 into RC by running 2wd and 4wd 1/10th scale and 1/8th scale trucks and buggies and have some of each to play around with, the more expensive one would be better if only for the fact it doesn't have a breakable antenna on the radio. I like it.
