I am about to purchase a JR system......this is after 20 years with Futaba 35mhz. The simple reason is that Futaba don't do all these satelite recievers with the flight recorder/data logger, and I want maximum coverage with a logger telemetry of what the system is doing rather than working blind all the time.
I have to say this is a reluctant change because I really like the Futaba programming and hate the JR system programming as I find I cannot get the settings for my turbines on the JR that I can get on my Futaba (I purchased a JR 9X mkII 3 years ago then sold it 4 weeks later because I hated it). That said I am willing to forgive the JR for anything now, provided it can give me a near bullet proof link to my machine. I believe that the JR system with it's 4 recievers and eight antennas has to be the answer over the Futabas single reciever. So lets hope it works.... I'm sure it will.
As for Futaba, come on guys get your ass in gear and build some recievers with greater coverage.....please.

Umm, futaba's 2.4 doesn't need the satellite receivers. The way its 2.4 operates eliminates the need for them. You should do more research into futaba's 2.4 system before you give up on them. Also, programming wise, futaba is a huge amount cheaper than any JR system. Take the 12fg for instance. I can get one for less than $800 right now, and the 12fg can do all, the 12x can. Also the 12fg you can update the firmware, and assign switchs. (forget about being able to assign switches to any jr radio unless you want to jump through a bunch of hoops).

I would recommend looking more into futaba's 2.4. Sure, they might night have data logging features, but the money you will save going futaba vs jr (i'm talking feature for feature pricing, don't try to compare a 9x to a 12fg, because the 12fg blows it away), you can buy an eagle tree data logger and get all the info you need. Plus how often do you really want to take your eyes off your bird to check something on the radio for the telemetry. Personally I just have a timer and I never take my eyes off the heli.

You know you have to many heli's only when your wallet is empty.

With all the crashes due to brownouts with JR/Spektrum 2.4 systems I would recommend you reconsider your decision. I have been flying Futaba 2.4 since they came out with no problems but have seen more than a few JR brownouts cause crashes.

You seem to have many RC machines...did you consider the cost of buying new JR receivers for every one?

You might want to go check some prices. Futaba's 7 channel is 99, its 8 channel is about $140, and its 14 channel is only $200. Jr's has no 14 channel, but their 12 channel is $230. So futaba is a lot cheaper, plus with the larger channel receivers, you won't need 2-3 satellite receivers, and have to find places to put them.

The only receivers futaba is more expensive with (not even by much at all), are their micro ones, but if you are doing anything large, futaba is cheaper.

I am not sure I understand this statement. What coverage are you referring to?

I recently switched from a 9Z to the 12FG and couldn't be happier. My local flying buddies (who were JR before) all bought 12X's. For there $1400.00 I got a 12FG, 14 channel reciever, Futaba transmitter case, free 6 channel reciever, another 14 channel reciever, an 8 channel reciever and the new 4 channel micro reciever.

A few things in defense of the 12X, the screen is nicer and comes backlit. I have modified my 12FG to backlight it though. The JR 2.4 radios have model match, and this is something that sold most of the guys at the field. If you have a lot of models, I can understand the need for this.

All that being said, I have heard of problems on both sides of the fence. Spektrum with random hits and failures, Futaba with the whole reciever heat issue.

and customer support, JR has great customer support. I have herd of several cases here on RR of people getting horrible support from futaba, and none about having good support.

Cost for me is not an issue, it's all, about reliability. Now I'm not suggesting that Futaba is at all unreliable, no way!
What I was concerned about is that on doing my research I spoke to somebody at Futaba who kind of admitted that a piece of metal the size of the palm of your hand placed between you and the reciever could and would drastically shorten the range. It was suggested that the reciever should be placed where the tranmitter could 'see' it at all times. Now I know that the Fixed Wing jet boys use them and that they fly out for 'miles' BUT as you know a helicopter is just one big 'screening' device and it's all metal and corbon as opposed to wood and glass so there can be no comparison. The problem then as I see it with the Futaba is that with only 1 unit there is no place that it can be put where it would be seen at all times by the transmitter. Now I know many use this system and have had no problems, but I have a large and now very very fast Wren Predator, it's not unusual for it to run out 400-500 yards, and this is where my Futaba guy hesitated in his explination. And so here I am reluctantly buying a bloody JR. As for the data logger, well that can be veiwed on the ground after the flight and this logs the recievers performance during the flight.
The reason for this post is the hope that some applied pressure will make Futaba come up with a system like this too, it's not meant to be at all malicious, as I have said I am a Futaba man....

I wouldn't be too worried about range with heli applications.

I know quite a few people on the fast systems, and a few of them have BW stratus's. Mind you this heli is over the top with cf and aluminum. I've seen them multiple times fly the heli nearly out of site doing auto's (atleast 4-500 ft if not more with altitude alone since I'm only 19 with decent eyes, and even I lose where the heli is), and not once have they had an issue with range nor latency.

I believe you will be very disappointed with JR's systems, and just need to take another look at futaba.

From what I have seen with the fast system, as long as you have the antenna's mounted outside of the carbon frame (you will have to do the same with jr), they can be inside the canopy, and you will be fine.

Trying to compare futaba's 2.4 vs jr's 2.4 is like apples and oranges. Both use different principles to effectively control the aircraft.

You know you have to many heli's only when your wallet is empty.

It's been a while since I've seen a Futaba VS. Jr thread so I guess the time has come up.

+1. Even more true with the FASST system IMO. And... more satellite receivers still doesn't guarantee a bullet proof connection. Flame suit on

The Rx itself is not the receiving part It just accepts the signal from the aerials and tells the servo's what to do.

All you need to do is place the last 2" of said aerials where it can get a reasonable reception.

On the FASST Rx's there are two aerial which you orientate at 90 degres to each other. The FASST Rx's aerials are longer than SpeKtrum/JR so can be located a similiar distance apart to a Speccie RX with Satelite.

The FASST Rx's use a coaxial cable where only the last 2" is the the part that matters.

The aerials have a micro coaxial connector inside the RX allowing you to change the overall lenghth of the aerials for specialist applications. A good example being carbon Composite sailplanes where its nigh on impossible to fit a JR/Speccie system. F5B being another example.
You run one aerial down the Fuzz and expose it at the rear (2" mind)/ through a hollow wing or exit the Fuzz somewhere on the top/side where it cant be damaged or just run it to a point where there is no carbon.

Longer coaxial cables can be sourced should you require length.

I think you are over reacting as although shielding can take place (hence two aerials) its highly unlikely in practice to be totally blanked on one aerial let alone two.

Blanking the signal is not as easy as it sounds. I can sit my Tx 12FG inside the boot of my estate on the loading floor walk round the side of the car 30M away turn the heli so the aerial are shielded by the model itself Carbon/Metal without issue.

If you want to stay Futaba and are convinced JR/Speccie is the only answer you could fit a SpeKtrum module to a Futaba TX

BTW I also have a DX7

Hi BB,

I've just swapped over to 2.4 FASST I have always had Futaba BUT was going to changed to JR as I like their smaller antennas, easier to mount and orientate to 90deg. I don't like Futaba's long aerials even though it's only the last inch or two that really matters on them, I'm still finding them difficult to mount/orientate at 90deg, at the moment I have just tucked the aerials down opposite sides of the rx and slighlty angled down, not sure how well this will work ? As I've already got a 14mz it was cheaper for me to buy a module and couple of rx's to try. If I don't like it then I will change over. I've only just finished putting them into two Eagle 3's, first range check and flights will be tomorrow

Simon.

What quite a few folk are doing is to attach a small piece of tubing to the aircrafts frame where the aerial is to be placed. this allows you to slide the aerial cable into the tubes both protecting them and allowing quick removal

Yeah I've got some tubing which I've heated up and bent but it's fixing them to the heli, it's really awkward

Also, if you need to run the aerials (like one inside and one outsite the fuse) then you can buy the FASST extension (400mm) aerials. You can change both or just one, 5 minute job.

BTW, I also went JR for a while, "felt the difference". I have been flying FASST for 1.5 years now, not a single issue. Helis/Jets/airplanes.

Thankyou Gents for your thoughts, I am still feeling more reasured buy the thought of a multi antenna system since 2.4 I know is so directional. I am going to test this system very thouroughly against a Futaba 2.4 and I will post my findings here with video for proof if proof be needed. So may the best radio manufacterer win! And the winner gets to go on all of my turbine machines. It would be nice to think that their is little in it between the makes, however we shall see. These will be back to back tests under the same conditions at the same time so as to be fair and I may throw in a 35mhz set just for comparison. Should be interesting....
