Default Spektrum 2.4 module in my 9CAP ?

I am thinking of going to a 2.4 module in my Futaba 9 CAP. Can you tell me if it is worth the difference in price between the TM-8 made by futaba and the Spektrum module with the AR7000 receiver. I can buy 2 spektrums for the price of 1 futaba, but if the futaba is better, I will go with it. Thanks for the replies.

I don't think you'll be able to find any "proof" that one is better than the other. I've never had any problems with spektrum equipment, plus there are BNF planes if that is something you're looking at. As you said there is a price difference, so much that trying the spektrum out isn't really much of a commitment, in fact only about $30-40 more than just a RX alone gets you the module as well, and then you're set!

Dave I have been using the Hitec Sprectra module and Aurora receivers for about a year now with excellent results. The have a combo with two receivers and the module for a pretty decent price. Its one alternative you can consider.

Like Brian said; do you want to play with any of the BNF models from Eflite or Horizon? Spektrum/JR also have a lot more rx types available than any of the other manufacturer's and the prices are more reasonable than Futaba, but I think a bit more than Hitec.

If you're just getting into the 2.4GHz systems, which one to use out of the three mentioned is the subject of much discussion/controversy. You must stick with which ever brand you buy as they are all proprietary systems and will not work with each other.

Yeah, but most of the Spectrum receivers are obsolete, now that the new DSMX system is coming into use.

Since any DSMX compatible Tx is backwardly compatible to DSM2, the only obsolete Spektrum Rx is the AR6000 DSM1. Granted that as people Upgrade their Tx's to DSMX or buy new DSMX Tx's, they will most likely buy the DSMX receivers, but DSM2 is by no means Obsolete.

The 800lb gorilla in the room is Bind n Fly
Advocates of various brand often try to ignore this feature
However -Amongst all the flyers I know - this feature is THE biggest tie breaker in purchasing a new (or another) radio.
Model Match -some still say is not a big deal (tho it is to me )
Guys who would not be caught dead buying a new Spektrum- buy an older one to take advantage of the Bind n Fly.
Or they get a module .
Prediction: Interest in smaller models will grow - and the really big stuff -which requires dedicated flying fields - will continue to diminish
Why ? cost of driving will reach a trigger point for many .
A 100 mile round trip easily costs $20.00 or more .
No big deal to some - but -for others - yet another tie breaker in deciding which equipment to buy.
I don't like it either - and out here in the wild wild west - driving long distances is the norm.
I guess it's time to start midnight siphoning Mc Donald's cooking oil for my car -

What I did: Get the spektrum module and keep the 9C for small stuff, BNF foamies etc. Then get a new Futaba tx with FASST for big stuff. One thing to consider also, the spektrum module uses ppm which is only 512 resolution. My new 10CAG with FASST is 2048. The 512 was very ratchety on my high end titanium geared hitec digitals. Very smooth on 1024 or 2048.

So the solution is to have both for me. The 800 pound gorilla is welcome here.

Umm.... I think that the Spektrum module/AR7000 rx combo is only $20.00 more than buying just the rx....

This is not True. Spektrum is 1024 or 2048 depending on which RX you are using.
And just because the transmitter is in ppm mode, that only has to do with the signal from the transmitter to the module that you plug in. the module produces the rf signal (notice how the antenna is attached to it and not the Tx?) which goes to the Rx and that is 2.4 gHz, PCM digital code, NOT PPM.

$109.99-$79.99=$30.00, however I dont see the the ar7000 on horizon's site anymore.

I'm not seeing your logic here. How do get 1024 or 2048 from 512? You can't "create" 1024 or 2048 out of 512 from the tx. The tx determines the resolution at the start of the data source. It's like saying you can create HD TV out of low def TV.

While it is true that the Resoulution of the Transmitter is what determines the resoulution of the signal, the PPM signal matches the resolution of the PCM for the given transmitter, which would be 1024 for the 9 CAP. My 18 year old Z-PCM JR x-347 is 512, and the spectrum module there would be limited to 512, but plug the same module into my 10X, and we're at 1024.

Compare to AR7010.

are they going to start packaging the 7010 with the module?

I see no issue with that setup to get someone started as the DSM2 protocol is still viable and supported as well as the fact that the modules (with the exception of the 12X MV) do not support DSMX.

I switched from Futaba to JR in 1997, So I guess I'm not sure. The 9C is a pretty recent radio, i.e. was manufactured this millenium, right?

The 9C is a pretty old radio buy today's standards. It's a decent radio but the electronics industry has evolved so quickly that today's transmitters are way better. I'll probably buy a new transmitter every couple years. I currently have the 10CAG. It's native 2.4G. No module, no antenna sticking out from the back. It's a nice radio but they are getting better every day. The 8FG with 14 channels and assignable servo channels is pretty amazing for the price. Futaba shocked me with that one. My buddy is about to get one.

For foamies my 9C with Spektrum module is awesome. I have never had a radio glitch in 2 years. For large gas planes it's FASST only.
