Status: offline 		Well posting the same question in multiple places violates RCU forum rules. Then when you don't take the advice/comments given because you don't like the answer and post it somewhere else, then you are violating the rules and exhibiting behavior normally associated with trolls.

Onewasp has given you the appropriate response regarding the use of aftermarket items and the text from this thread, to which I will provide you a link to as it seems you were not able to find it. Kind of funny that onewasp and I can find it but you can't....

Now go ahead and do what you were going to do regardless of the answers you got to your question.

Status: offline 		I have a question about the Spektrum radios....I bought a new radio about a year and half ago which is the 9303 with the
synthesized module and also I use the 955 and 945 receivers....I'm thinking seriously of changing to the 2.4

What would be the best move to make if I'm going to switch to spektrum.....replace my Module and receivers on my 9303, or just buy the new 9303 that is already set up and add more receivers with it....is there any advantages to either choice?

Thanks for any help or opinions,
Bill

The module setup is less munney
The X9303 has Model Match - which none of the other guys have - NONE of em
If you keep the radio for a while and add more rx- the model match is a very good thing

also the value of ANY 72 mhz based radio is dropping - as example I have been offered Futaba 14 for 1000 bucks - I turned it down. Good radiobut that is what happens when new technology and good marketing change the picture
The 9303 is one of the best 72 radios in that it has excellent programing and a good match of elevators built in - so - really it is a matter of spend now --or later --

Status: offline 		A couple more reasons to go with the new X9303 instead of a module...

All a module will do is convert your frequency band to the 2.4GHz range, so there's no change in the way your XP9303 handles the conversion of stick inputs to data so it can be sent to the rx. Some folks claim the 2.4 module is faster than the 72MHz modules, but I suspect that may be anecdotal evidence.

The new native 2.4 X9303 also has servo synch where say dual (separate) elevator servos are grouped together and sent at the same time, so there's not a lag issue to deal with there. Then there is the fact that the native system is designed from the ground up to use the new band and it's capable of handling more data than the 72MHz, broadband if you will. In fact, comparing a native 2.4 system to a 72MHz system is a bit like comparing dialup Internet access to Broadband Internet access, it's just plain faster. This is where you get the faster control response from the model and what lots of people referred to as a "more connected feel" when the DX-7's first started being used.

Though I live in a rural area, I enjoy flying in the cities at fun flys, etc. & have always had the worry that someone could "turn on & down me".
I called Horizon this morning. The new radios are currently out of stock & have to be backordered. They did have the equipment in stock to turn my XP9303 into 2.4, but I'm considering taking your advice.......
It's nice to be able to hear the opinions of others who have experience.

Status: offline 		A lot of the discussion in these forums about reasons for going to 2.4 is about being shot down by lack of frequency control, nearby ‘park flyers’, dial-a crash transmitters, people taking the wrong pin, etc.

A lot of competitive events, fly-ins, rallies, etc. use different frequency control than the flying field has set up for regular club use. In the past year, I have personally witnessed three occasions where a pilot was registered on the wrong channel due to a clerical error. In all three cases, the error was discovered before anything bad happened. As long as humans are filling out forms these errors will happen.

Status: offline 		I won't go into all the details, but we had a member lose his model at our annual club open house where we had guys running a tx impound. He was flying and the impound guys gave out another tx on his frequency and the rest is, as they say, "history".

So is all of my 72MHz stuff...

Status: offline 		I've been flying a C-ARF Rookie turbine jet for two years with the JR9303 and 9-channel Rx that came with it. I have over 180 flights on it. Today, I flew three times with the Spektrum AR9000 Rx and DM9 Tx module. On the first flight I could tell immediately that the latency was a lot less. For about the first 6 minutes it was like flying a new jet over again. It was the last thing I would have thought would be different. I was more concerned in the back of my mind about what my readings were going to be on the Flight Log after landing. I also added a second remote antenna for these first flights. To say the least I was pleasantly surprised with the better response with this Rx and the fades were very low.

Prior to these first three flights, I flew this Spektrum combination in a 60 sized prop plane to ensure the system worked before I put it in my jet. I ran 5-cell batteries in both. I want to point out that I have had some issues with binding the system with the second remote antenna. The antenna LED never seemed too cooperate with the rest of the LEDs in the system during the binding process, but nonetheless, I was eventually able to get a solid LED. I’m still unsure why I had trouble. I have also seen some other unexplained issues that leave me somewhat concerned even though I flew successfully with this system. One is the fact that I can cycle through the Flight Log and see that all antennas read zero, but number of total fades actually shows a number. With the success of these three flights today, I will continue to fly this Rx system and monitor setup closely.

Status: offline 		Some of the local pilots at my field seem to think that i am doing a disservice to the new members because I push 2.4 when they are ready to move up. They tell me that because 72 is that much cheaper on the used market I should direct them in that direction. Not withstanding the fact that I loose a sale by suggesting the used market, I fell that the new member not having a lot invested in radio equipment and the fact the both types of radios new are within $30 buying 2.4 makes more sence. I know some of them have told the new guys to look used and save money. As a LHS owner i fell it is my duty to explain everything thing to them and let them make a choice. What do you all think?

My two cents,

When I was a lad-- the question was about buying another horse -or getting a car -
I know there are still 72 mhz radios for sale -but just can't figure out why -
