I agree with your thoughts, and have had the same myself, but I do feel Futaba has worked their issues out, and they are having people ship their 2.4 equiptment back to get checked out and updated if needed.
I too am leary about ANYTHING that has just hit the market too. I am thinking of buying a 2.4 9303, as soon as someone can tell me about the switch assigning capabilities, as compared to the Futabas. I need to find out IF it is possible to assign the throttle kill switch to the location of the trainer switch w/ spring tension.
???? Anyone care to tell me if this is possible on the JR 9303?
I need to also figure out how many channels the 9303 is capable of having, and which Rx will give me the most channels? I really would like to have 10 channels on this next radio I purchase. I will actually NEED 10 channels, to prevent having to use Y harnesses, which I absolutely hate.

Paul,
The 9303 does not have a throttle kill switch, you can create one by using a P-mix and hopefully assigning it to the trainer switch.
The JR 9303 radios sold in the US have mechanical trim for the throttle, so most 9303 users in the US doe their throttle cut the old fashioned way.
I flew for almost 20 years doing it that way and now have one year of flying with digital trim with spring loaded throttle cut, just me, but I would not want to go back.

Yes, I agree, I would NOT even consider using an analog trim to kill my engine. Screw that.
I'm disliking the JR more and more. You have to actually use a MIX to design a thr kill? Good Lord.
Well, anyhow, just to be fair, I just checked Cheif A/C's site, and looked at the 2.4 9303.
It looks like I can have ONLY up to 9 channels with this radio.
Can anyone tell me WHICH Rx I will want to buy with the JR 9303?? I see Chief is offering it with the "R921 DSM2" Rx, and I'm a bit confused about a couple of things.

1. What is the deal with the "AR9000" or "AR9100" ? Rx's I keep seeing people mention, and how do they differ from the "R921 DSM2" Rx that comes with the 9303 at Cheif???

2. I read about the "R922 DSM2" Rx from JR, and it says it has a "soft switch that fails in the on position".
What is the deal with this "soft switch"??? Does this actually take the place of dual, redundant switches that I've always used with my Giant Scale 72mhz planes????
I mean, IF I switch to 2.4ghz, will I still need to run TWO redundant switches with this new 2.4ghz setup or what???

I'm still trying to figure out a few things about 2.4 guys, so bear with me. I'm doing all the reading I have the time for...


BTW, why on God's green Earth would JR give people OVERSEAS a digital trim, but give us the shaft of an analog trim???? I'm trying to make sense of that....

well --- actually we far prefer the analog trim -
It is a thing which typically is a result of a fair amount of experience and the ease in setting low speed throttle as required .

I can see how some would prefer not having a digital trim, but as for NO throttle kill function without programming a mix, that just hits me right where it hurts...

Can somebody comment on the difference between 1024 and 2048 resolution based on actual fly experience?

The 9303 does not have a "spring" switch--

Easily done with one of the mixes

If memory serves me correct, Horizon researched many fliers when they were upgrading their JR 10 SX series radio to the 10X, as well as people that flew some competitors radios. One of the biggest complaints and wish list items was to have an analog trim on the throttle instead of a digital trim. At that time, most people responding wanted a traditional trim lever to set idles and cut throttles quickly. Many disliked having to continually bump a digital trim when they could set an analog, once and quicker. Some felt the analog was more precise than having to adjust a rate for the digital and they could repeat a setting more consistently. Others did not like having to remove your hand form the stick to push a kill switch. With the analog, the trim lever is easily accessible without removing your hand from the stick.
I believe the actual trim functions are digital, it is just that the trim lever is used to mechanically adjust the setting instead of using a spring loaded switch to adjust the function. I know the trim and subtrim settings are in the same menus as all the other digital functions. You can verify this on the JR help site here on RCU.
Another reason they offer all digital versions of the X9303 in other parts of the world as the JR 9XII, is because some fliers use mode 3 and mode 4 stick configurations. Having all digital trims allows the option of flying any mode,1,2,3,4 by just changing the programmed setting. There is little if any call in the US market for mode 3 and 4. Some people buy the JR 9XII and use the JR/Spektrum modules and receivers here in the USA with great results.

Two additional thoughts, you can have a spring loaded switch installed on the X9303 or use the pushbutton trainer switch. Also, the heli version transmitter has a spring loaded switch already installed and contains all three types of programming as well, just different switches.
There is a fine line about the legality of using a non US version of a radio in the USA. It has to do with type certification issues, plug in modules, power output, etc.But, as they say, that is a whole different discussion.

Well -- actually the we is quite a few flyers -mostly those with a fair bit of flying experience -and typically competition flying - but use what you like - Post 60 is on point -

I've been flying since 1965 and am still flying IMAC so I fit the above description and we, my black cat and black & white dog prefer to fly digital trim on throttle and use a three position switch for throttle down and throttle cut which we've found to be faster and more reliable than a mechanical trim lever. But then some old dogs are harder to teach new tricks.

How can I get a spring loaded switch installed on the 9303? Also, will I be able to put it up on the TOP LEFT, where the usual spring loaded trainer switch is installed on a Futaba 9C/etc?
IF INDEED I CAN have it installed in this location, what switch will it replace? Or should I say, what is the purpose of the switch that is already in this location, as when the Tx left the JR factory??? Will I be replacing something important, or will I be removing something that I don't really want to remove?
I'm just wondering who can do this switch swap/where can I get it done? I've never heard it mentioned before.
Thanks for sharing my friend!

After reading this thread, the "official" release thread and every other one I can find, I've placed and order with Espirit. My feeling is Futaba has taken more than enough heat over the 9C's mixing speed/latency issues and I believe the supposedly all new digital circuitry and faster CPU will make performance equal G3 FAAST spec, at least when using 1024 servos. Personnaly I'd be tickled pink to have affordable giant scale servos and a radio that ACTUALLY could do 1024 with some speed. I've seen discussion here and elsewhere on resolution and it seems we arent getting anything like 1024, and IRC, Multiplex was one of the worst for low res. yet they are popular, so its not just a simple numbers game.
BTW, I ordered form Espirit hoping they would be less deeply backordered.. I bet Tower is already sold into the second/third shipment despite a hopefully large alotment.
And yes, I will be squealing like a stuck pig if Futaba doesnt ship by MAY 1, hehe.
I decided my intended IMAC use made the 14 ch RX first batch systems a deal ($200 rx there, OMG) on the assumption I can do my 35% plane with no mix box with channel assignments on the RX.
Also just have to say my purchase was also LARGELY due to the MODULAR design so many have said KEEPS them from buying the "C" series and up. I have an Xtreme Link system, a Plantraco Monolith and homebrew IR systems so I like my versitility. Also I have literally
dozens of FM(mostly parkflier/indoor) Rx's so no way I'm switching wholesale to SS, especially since SS rx costs are still radical in my view.
So I will be looking for the FM module for the 10C when it becomes available. Then my 8UA can rest after 8+ years.

Ok crossup, so I'm not even sure what you have purchased, or are waiting on??? The 10C????

superdave01

I had a Futaba S....L....O....W 9C, then switched to a JR XP9303, then added the 2.4 Module and NOW have a JR X9303 2.4.....

Model Match is plenty of reason to go JR, for those that say its no big deal well then i guess you just are perfect and NEVER screw up.

Not considering Model Match at all the 9303 is still much better, 7 point curves even 2 for throttle in acro mode, set both directions speed of any servos, 3 FLight Modes < KEWL!!!!! and so much more......

I have to say i absolutely LOVE my X9303, something ive never said about a transmitter in 28 years of this hobby.

The Futaba 2.4 stuff seems to be reilable but ive noticed you have to use THIS reciever with THIS transmitter and also the signal voltage on some of them has issues with some servos, a friedn had to buy a Smart Fly to get his signal voltage high enough that his Hitec 5955 servos would work.

Bruce--When I looked at your posted Futaba link on receivers I noticed the 608FS & 6014FS both listed for the 10C and both indicate 2048 Resolution. This link seems to answer the 1024 VS 2048 resolution issue we have been talking about. Anyone see it different ?

pilotpete2

I just looked and I think you may be on the right track, you will also notice that when using the 8 channel or the 14 channel you must switch to multi mode rather than 7 channel mode. This could very well be an indication that from 8 channels and up FASST is 2048. Could this mean that the TM-8 module does 2048 resolution with the 8 channel receiver?
I think we will know more when the Runryder Heli guys get their hands on one and they give the numbers to show where it comes in as far as latency goes[8D]

I believe the resolution comes from the transmitter and not the module. As for the 8 channel receiver, I asked Krysta at hobby services if it would operate at 2048 and she emphatically said yes it would. I have the 12FG with one 6014 receiver. Most of my models can operate on 8 ch. or less so i'm waiting for their release next month, (or whenever it really happens, patience is a virtue), to pick up a few 8 channel receivers.

flying buddy received on 608 fs rx today.
yes it does operate in fasst multi mode.

pilotpete2

I was under the impression that PPM did not have discrete steps as in PCM, but that it was rather more of an analog deal, as the pulse is shifted in time, I would think that this would make PPM finer in resolution than even 2048 in theory, not that one would ever know the difference with the sport servos I fly
