I am posting this here as I usually get good results. I have a 72mhz JR 8103. I've been reading about the 2.4ghz technology. People have different reasons they want to go to 2.4. The only reason I would be interested is if switching would give me any more "perceptible" control over my aircraft. I do some 3D and my main question would be does 2.4ghz give you better feel?
I understand that latency is decreased by several milliseconds, however, I am unsure as to whether you could tell a difference since this is so quick.
Another advantage they propose is "servosync". Not real clear on what that is though.
I'd like to hear from people who have made the switch and know if their "locked in feel" (as the 2.4ghz ads say) is better with the newer technology.

I switched because one day when I went to the feild, me and another guy were on the same frequency. We had to keep taking turns flying, and since I don't get to fly near as much as I would like, it stunk that my "air time" was cut in half because of a frequency. It was worth it to me to go 2.4 so I could be assured that I would get as much air time as I wanted when I go flying. Its also nice to not have to worry getting shot down by someone on the same fequency. As far as a more locked in feel; I cant really tell a huge difference.

Are you familiar with digital music? Some people think they can hear a difference between a high-quality MP3 file and a CD. I can't, but perhaps my ears just aren't that sharp. In the same way, I don't notice a perceptible difference between 72mhz (PPM and PCM) and 2.4ghz in terms of feel. Maybe you'll be one of those that does, maybe you won't.

[color=#FF0099]I fly with a Futaba 7 CAP. I've got a Futaba T6ex Fasst, but the receivers are so much more expensive that I can't justify the switch... Also, I know 95% of my channel buddies and we rarely have trouble sharing the frequency (plus a couple have now gone 2.4 and that leaves more time for the rest of us.

There is no difference in the way the servos work between the different transmitter technologies. The only thing that 2.4 give you is the fact that the receiver is bound too the transmitter that is used, end of story. The transmitter incoder is what is used to control the servos, 2.4Gig is the transmitter frequency used as 72mhz was used in the older sets.

I switched to 2.4 about 2 years ago and have seen zero difference in what you ask. Going to 2.4 is the best change I have seen in my 37 years in this great hobby. I recommend it.

All the big 3D guys fly 2.4 systems, you know they wouldn't if the lag was noticeable.

Ghost I may be incorrect , but I was under the assumption that 2.4 Gz is the band width in wich the transmitter will work not so much the frequency itself , in that respect 72 mhz compared to 2.4 Gz is like comparing apples to oranges , there is no comparison 2.4 Gz gives you 100 times the available frequency options because it is continues to search for one that is a available and not being used at that moment in time within 2.4 Gz bandwidth ( in plain english ) you would have example ......100 available frequency with 72 mhz and 10,000 available with a 2.4 Gz

ZERO, what I was saying is that the 2.4 gig systems do not make the servos work any better, it is the encoder in the transmitter that is responsable for that, the 2.4 gig band is only what the encoded signal travels on.
I switch from a JR3810 (on 36mhz) computer set to the DSX9 (2.4) and there is no difference that I have seen in the way it controls the aircraft(speed at which it works), I have been using digital servos in all my aircraft for several years, don't know weather this is the difference.

Servo synch is taking channels that perform like functions and transmitting them at the same time.

An example is dual elevators. With a 72mhz Futaba system the channels are polled and updated in order and if your elevators are on 1 and 6 then channel 1 gets its update, 2, 3, 4, 5 then the other elevator servo gets its position update.

This creates a noticable lag.

With 2.4 systems I can tell a noticable decrease in control lag when flying helicopters with high performance servos, on a typical airplane I cant, on a 3D gasser with good servos I can.
