2.4 ghz - transmitters

guys,

i've been looking around the net to purchase a 2.4 ghz transmitter set. However the vary in price from £45 to £ 450. Can anyone provide me with suggestions as to what I should be looking for when going to buy a Transmitter. I suppose it's got to be 4channels up: two for drive, one for weapon, and one to turn robot off or on? What mode 2 or 1?

Here is the links to the transmitters i've been looking at.

Your opinions and comments would be great.

You could use this set to convert a 40 meg set if you have a decent one,

along with the receiver,

Grab a cheap old 35MHz/40MHz transmitter off of eBay, such as:

http://cgi.ebay.co.uk/Futaba-Skysport-6 ... 415b546cb1

Then convert it to 2.4GHz using DIY kits. This allows you to use all the fancy features of a more expensive radio but means you don't have to fork out lots of money to be using 2.4GHz. The conversion process itself is very straightforward and involves drilling a couple of holes and soldering a few wires.

I've used the Corona modules, that Gary has linked to, in the past. But they've not been 100% reliable for me, and since I've used FrSky modules, I've not had any problems. Instant bind, programmable failsafes in the receiver, and nice and cheap :)

The FrSky DIY module:

And 4-channel, 7-channel and 8-channel receivers:

http://www.giantcod.co.uk/frsky-receive ... 05458.html
http://www.giantcod.co.uk/24ghz-frsky-r ... 05319.html

And, if you choose to opt for this method, a few posts from forums that go through the conversion process:

out of that list i'd say your best bet is dx6i, i use one and it works well and has programmable features which is nice. my favourite transmitter though has to be my hitec ranger 3 40mhz, trying to snap another up and convert it :)

jonny- i think mr kent (my tech teacher) has a couple, they may be 35mhz though

Might try one of these things on Eric's transmitter, I forgot how expensive a 2.4gHz transmitter with enough channels would be so this might be a good alternative.

:sad:

harry- awesome, can you ask him next time you have tech?

will do

good input guys.

Just a quick question, does all 2.4ghz transmitters have a fail safe when turning on/off or loss of signal etc? Or doe sthat depend on the RX purchased?

Also I know with the 40 mhz systems you could use a futaba transmitter with jr RX as long as the crystals matched, how does this work with 2.4ghz? will any receiver work with any transmitter now?

no

1. depends on the receiver

2. no

Different manufacturers have different methods for connecting transmitters and receivers but the overall method is for the receiver to be bound to a transmitter. Generally the transmitter emits a specific code which the receiver is listening out for when it's turned on. When it gets this signal it will act on the instructions that the transmitter sends.

Different manufacturers 2.4gig radio gear will for the most part NOT work together as they are looking for different codes and use different methods to bind.

thanks for the help folks

HI which 24ghz-conversion would be compatible with a futaba t6x.
Thanks
ROB....

All should work, they connect to the back of the trainer port, and read the PPM stream. Ive used the FrySky hack system on a Skysport 6 and a 6EXA, with no problems. Would really reccomened these, i bought one of the modules to fit my FF8, which I use on the mechanoid. Never had a problem with range, bind instantly.

Frsky i think

Cheers I will order the frsky then.
Just hope i can get the wires soldered to the right pins. :crazy:

Can't find a BR6000 for your dx6

Quote from a RC Forum.

Good find! Was hoping that I wouldn't have to get rid of my DX6

Planning on throwing a FrSky system into my cheap GiantCod transmitter the next time one of their receivers craps out on me. It also seems to have the same three wires out that you can just solder a hack module on to. I'm liking all this cheap DIY 2.4GHz business, saves a helluva lot of redundant transmitters being thrown out :)

It also means that you could pick up a dirt cheap 40 or 35 meg futaba system that would have cost several hundred years ago and convert it for comparatively little money.
