2.4ghz

[Stuart]

Since the introduction of the new 2.4ghz systems. I'm interested to see how many of us are looking at moving to this.

I'm personally not in a hurry to change when you consider that 2.4ghz is widely used frequency from Wi-Fi to wireless security camera's and much much more. I wonder how secure these channels will be for our use.

While 35mhz is ours period.

This is not to say that technology will prevail but is it secure enough as it stands now.....So let the debate begin.

[Steve]

My thoughts exactly Stuart. I'm of the same opinion as you - there's no hurry, let's wait and see.

As you say, there's a free-for-all out there on this frequency, so I fail to see how it's going to remain safe for RC use.

I'd be afraid that it would get so popular that you get to the patch turn on the TX & a little screen popped up saying sorry frequency busy please try again later

gonna stick to 35 meg for a bit.

[rambo]

dont think there will be a problem with other 2.4ghz stuff such as wireless routers etc; as 2.4ghz is designed to work with each other


just a quick edit......35mhz is not actually all ours....the lower end of the band is used for some sort of transmission thingy (not quite sure what), but it is as clear as punch on the OFCOM website

Well I've been using the DX7 with no probs. All the skeptisism is perfectly natural, but I understand the technolgy and happy on their implementation.

Someone suggested that if I have the phone near it, it will wipe the memory!! That's how skeptical people are.

IMO there are more risks to using 35mhz than 2.4Ghz. It only takes someone to switch on to your frequency to give you a bad day.

The only issue I can see is the TX isn't as good as a 9X.

Also I've never had a glitch with the ALLL carbon TREX of mine

[gazza]

Just think of all the mobile phones in use & they all seem to get on okay

Am sticking with my trusty 10X for now...Thats not to say I wont get the module for it though

2.4 rocks not only in safety but in response time also, all the leading manufactures are now into production of there own 2.4 systems imho its the way forward and a godsend for busy club fields.

All this 2.4 is running at my place -

5 - 2.4 cameras
2 - 2.4 video senders
1 - 2.4 multimedia transmitter and broadband wi-fi not a problem in sight.

I've switched nd like it, not too many WiFi devices and no security cameras at out site

Though some idiot was playing with a 2.4g transmitting camera without a clue wether it would cause a problem to a heli, it wouldn't but he didn't know that.

I have been on the Spektrum for a while now and it has saved me flying my Raptor on the Trex settings and I have only crashed the Trex 450 once in 2 months instead of every other outings, so the (would be) repair bill has paid for the TX. I have just installed the Spektrum servos into a Panic (I know people think they are crap) but I quite like them, they should be fine in there in my opinion.

Only issue I have rarely seen with my Raptor is once that once in a blue moon when I turn on the system binds I get nothing from the controls. If I turn off and on it will work fine, I think it may be the receiver but I am not 100% sure.

I do love the feel and the response to it, it is like I have upgraded all my servos to faster ones just by installing Spektrum.

why can't the 2.4Ghz technology be applied to 35Mhz?
Probably no reason, other than the 2.4Ghz is a global spec so the market is huge, but 35Mhz is europe only.
Surely the binding technology and latancy advantages would still be available at 35Mhz transmission, in a "cleaner" band? 35Mhz at 10kHz spacing channels was introduced 25 years ago, so it mustbe possible to get much more data through in the same band width.

I can see where you're coming from but the 2.4ghz systems are legal in a large number of countries now and surely it will be cheaper for a manufacturer to make one spec transmitter for the whole world instead of the UK being one of the few on 35mhz? I'd like to think the savings in production costs would be passed on the the consumer, then again probably not! It would certainly increase the size of the market you could buy from, no more worries about ending up with a 72mhz system you can't use.

Been on 2.4ghz since it's introduction.....not interested in going back to 35mhz at all. You can have 80 spektrum tx powered up at once and everyone can fly without interference or fear of being shot down. The 81st tx will not transmit until it finds a spare slot to transmit on. Can't see a good argument for 35mhz IMO.

[G-DAVE]

Stop fretting about 2.4 Ghz just do it !!

Same here - using 2.4 Ghz since December 06 , no problem .
I agree it's wise at the moment not to jump to each new idea that comes along "WAIT AND SEE " .
I'm not convinced about 2.4 Ghz modules for existing 35 mhz sets it somehow seems to good to be true , there must be a down side.

The down side seems to be slightly higher latency than the DX7 plus no model match so you muct check model memories before switching on! I'd certainly miss the model match but looking at the tests done, the latency of the PCM9X used with a Spektrum module & receiver is actually less than if using PCM, although higher than the DX7, I dont notice the difference between the PCM9X on PCM and the DX& now so not a problem for me!

[ChrisB]

Used the DX7 since its introduction

2.4 ghz is good because 35meg is where metal to metal rf noise hits and so does brushless motor and esc interference

So thats why its partly 2.4 also as mentioned its a worldwide standard frequency

So a Spektrum type system on 35mhz is pointless

No problems with mine and i would never go back
