So far the best technical explenation in the internal workings of the DX6.

Grant I dont think you read my post properly.

All I said was...

- The information supplied states there are 79 channels available
- It also states that a unit requires 2 channels

Thus surley it would be logical to derive from that data that you can use a maximum of 39 transmitters at once rather than 79 ? Or can transmitters share a channel - the Spektrum data says no as it makes great reference to how it will only lock to a free channel.

If the DX6 will work with only one channel then yes you could run more, but weve already seen in the text - the DX6 will only lock onto a free channe. So once youve turned on 39 transmitters there are no more free channels to lock onto.

Grant, Ive simply worked this out going through Spektrums own technical data, Im sure a manufacturer investing millions would have looked into their technical documentation and made sure its correct

It can either share frequencies, or it locks onto a free frequency - or theres some marketing jigger-pokery going on !

PS Leo - thanks for the link. Am glad an expert evaluating the unit agrees that the unit doesnt eliminate interference unlike our admittedly enthusiastic youngsters

Indeed it doesnt, but it is way less sensitive for interference, and that for me is a good thing.

For me its main selling point is that the receiver will only respond to the TX with the bound GUID, and discards the others as noise.

And since the amount of data being transmitted is not that much, you can cover a great distance.

In the UK they held RC boat races not so long ago, and loads of people there use spektrums. Most have said they wouldnt want to go back to their old systems, but there are known issues with very dry weather for instance. Now that is something both the UK and Holland usually have no problem with.

Even so, in robotic competitions i dont see us use more then 20 robots at the same time, so in my opinion how many TXs you can use at the same time seems a bit of a mute point to me.

I would however recommend turning the transmitters in with Transmitter control, so we keep the amount of active TXs in check. No sense in using more channels then is absolutely necessary.

For the people that alredy have a Robbe/Hitec/JR set with interchangable RF module, this might be a nice solution too.
