9303 PCM to 2.4 conversion

[Stainless Skills]

I have a JR 9303 that I would like to convert to 2.4

I thought that the conversion from the radio signal to the transmitted signal took place in the module. If I switch to the $300 2.4 system will I gain faster control response between my radio and my model.


How fast in 1/100'ths of a second is PCM compared to 2.4GHZ?

What is the difference between resolution, bits a second.

I have never understood the 2.4 GHZ locked in feel that everyone is talking about. How much more, in transmissions per second is the locked in feel? Can I get this locked in feel by converting my 9303 to 2.4 or do I have to buy a whole new radio?

Is there actually a locked in feel at all? I mean, in PCM you can not visually tell the time laps between the movement of your thumbs and the surfaces, how on earth can you tell a difference with the 2.4?

I can't give you all the numbers you are wanting, but after switching my 9303 to the spektrum module and rx, I could notice it a bit faster and more crisp. I flew back to back, so had a decent comparison. I did however just order a ground up X9303 2.4 since it had a few additional features that you cannot get with the module, and is as fast as the DX 7 with 2048 resolution.

Right now Horizon is selling the new 9303 2.4 radio's for $629.99 with no servo's and a 9 channel 2.4 reciever.

Brand new PCM 72Mhz 9303's which come with 7 channel PCM recievers are selling for $500-$520.

Right now, my 9303 has is basically in new condition, with awesome long shiny red anodized sticks. A brand new 1650mah NIMH battery and a 9 channel dual conversion PCM 649 JR reciever.

My radio, if it was not used, would be worth more than $520 but since it is used, even though it is in perfect condition, it could be sold for say... $450.

I would love to sell my radio for at least $520. I will even throw in an extra R770 reciever. If anyone wants to buy all my stuff for $520 please PM me.

That means I could take that cash, and then turn around and purchase a brand new 2.4Ghz 9303 with a 9 channel reciever for only $100 more bucks. Instead of the $300 that they are asking for the conversion.

I also have a like new 6102 PCM radio on CH 47 that has a new 1650 NIMH battery that I could also sell.

I think I want to sell all this stuff and buy a new 9303 2.4 Gig. That would be pretty sweet. So PM me if you want anything.

It could happen but when I got my first DX7 -I sold all my other stuff -and prices -even for new radios --with buggy whips , are likely to be a buyers market .

Keep in mind that the servo only option X9303 is not available yet, not for a while from what I hear. I just ordered the complete X9303 2.4 system from Sugarland Hobby in TX, it was $729. I am hoping to get back about $50 by selling the servos. The market is flooded with 9303s right now. I am trying to sell my 9303 with the spektrum module and AR 9000rx for $400 and no luck with that, nor selling just the TX, original module and 1500 nimh battery for $275. Tough market. I knew when I bought my Spektrum module and rx I would use it until a ground up system came out though. The best reason IMO to get the module version is if you want to avoid getting shot down.

Thats really tough, not being able to sell your converted 9303 for $400.

PM me if you ever want to sell the 2.4 module and reciever.

Yeh -it really sucks - but- this is the marketplace at work-in the real world
on a similar note -and in that you are 18 years old pay attention--(example)
a new Ford may sell for 20,000 bucks - and in less than a year -can be found on wholesale outlets to dealers for 1/2 price .
How can that be?
simply put - supply and demand - once a company say - Hertz releases a sh itload of low mile cars on th market - the price all over the country drops like a rock.
I sold my 9303 as soon as I made first flights on my DX7 - -I saw the handwriting on the wall.
next I EBayed my 10X- same reason - and got good prices for each as they ar both excellent systems and for someone who is content with flying on 72, a good way to go ----but that % of the market soon becomes saturated so further attempts to sell at same price become less likely - --business s usual.

I would go with xtremelink, it will only cost about 200 for the module and the 8ch receiver.

A couple of thoughts since I converted all my stuff to the Spekrum/JR 2.4GHz radios.

The used market for 72MHz is dropping like a rock. From what I've been seeing you'll be lucky to get $300 for your XP9303 and I've not followed what the rx's are going for since I had all Futaba stuff. When the first X9303's hit in late August/early September, the 9 channel PCM Futaba rx's I had were going for $100 to $120 a pop if NIB or really clean/low time. I didn't manage to get my hands on an X9303 until late October since I'd been waiting for one without servos. I finally bit the bullet and got one with the servos. I finally got the last of my 9 channel 72MHz rx's sold about a month ago, and I only got $75 a piece out of rx's that cost $160 each new, and one of those rx's was NIB.

The resale value on the 72MHz stuff is only going to get worse.

Now as for converting your existing 72MHz system vs. a new native system; yeah you can gradually convert since you can change modules, but you lose model match, servo scynch, and the faster data transmission offered by the native system as it has more bandwidth to work with and can convert your stick inputs to RF and get them to the model's rx much faster.

So yeah it's a bite taking the financial hit, but I figured I'd spend less converting now than I would later, and for me it was a bit easier as I changed radio brands as well so the choice was much more clear cut.

I'm glad I did it and I wouldn't go back...

I converted my Futaba 9C to the Spektrum module. It worked, but got no advantage except the 2.4 Ghz. band.

I flew it one flight and ordered the native X9303 which I love. Don't waste the money on a module, get a real transmitter.

I have to disagree with WILDHARE, I have the xtremelink module and receiver and think it is great. The firmware on the module and receiver can be upgraded with the new device that wireless connects you tx or rx to your computer. Soon xtremelink will have a firmware where the user can now run the transmitter is pcm modulation. Specktrum is ok, but it does not have the features of the xtremelink system. But yall can draw your own conclusion.

[Zeeb]

Those "features" are hardly enough to overlook the capabilities of the X9303 vs. your module system when it comes to flying a model...

I kind of enjoy tinkering with computers as well, but I'm more concerned in this case with how my radio control system performs in my models, than it's connectivity to one of my computers.
