Some 2.4Ghz Tx are advertised as Mode 1 and some as Mode 2. What the difference? Are 2.4Ghz receivers tied to a mode or can be used with any 2.4Ghz Tx, i.e. you need a mode 2 receiver with a mode 2 Tx.

No.    While there are two  (at least) types of 2.4GHz systems implemented that isn't what Mode 1 and Mode 2 refers to.    Mode 1 and Mode 2 refer to the way that the controls are set up on the joysticks.    A quick google will decribe the difference in detail.

As far as 2.4GHz compatability is concerned the best approach IMHO is to assume that only receivers specifically described by the manufacturer as compatible are compatible.   Even within one manufacturer's offerings not everything is compatible.

Thanks for replying.
I'm trying to get my head around the 2.4Ghz thing. Although people in the club have a variety of makes they can't really explain them to me. They seem to think that 2.4Ghz systems are siimply an extension of the previous freq ranges with the added bonus of a receiver bonding with a Tx.
From what I've managed to read the only commonality between the 2.4Ghz makes is the freq band. The technology varies according from make to make and to say one make is the same as another is like saying because an AM Tx or a FM Tx is on 40 Mhz are the same. So it looks like, as you were saying, the particular Rx has to be matched to be compatible with the Tx because the way the signals are processed varies from make to make. This is different to AM or FM where the signal processing is standardised within the mode so a FM receiver will pick up a FM signal regardless of make of source.

I've googled mode and only get convoluted explanations of setting up programmable Tx for helis. The nearest I got was Mode 2 is used in the US and Mode 1 in Europe.
Some say it determines which side the throttle is on, some say the mode is determined by whether the stick returns to the centre or is 'free' (no side mentioned).

Do boaters in the UK generally use mode 1? I ask because some club members have 2.4Ghz Tx with the throttle and rudder on the right. They just accept that's how the equip came while I suspect they have ordered the 'wrong' mode Tx system.

A link to any explanation of the jargon and compatibility issues for 2.4Ghz systems on the web would be welcome.

It isn't that complicated. For 2.4Ghz buy only receivers desined for your transmitter. These will typically be from the same manufacture of the transmitter. Sometimes older and newer generations of 2,4Ghz equipment from the same manufactures will not work togher. The manual of your transmitter will list receivers that work so its safest to stick to those.
For model boat uses Mode 1 essentially means Throttle (the ratchet) is on the Right hand Stick and in Mode 2 it is on the Left hand stick. In most Tx's you can swap over the ratchet yourself. If you not using a ratchet and using spring sticks, then it matters not what Tx you get. Most people I have come across prefer to have the throttle on the Left.

Most of the lads down my club have the throttle on the left stick rudder on the right stick. As far as im concerned us either whatever suits you. With 2.4 your trans is bonded to your rec. So no other trans will
affect you. No frequency crystals required.Ive got 11 recs bonded to one transmitter.All of course not
affected by anyone elses trans. As mentioned before the airials must be above the water line. 2.4 will
not work for subs. Use 25 or 40 for this. Most trans can be changed from mode 1to 2 and vise versa.
best to check with supplier. Range is excellent, but my futuba trans is a bit power hungry. John.

Thanks everybody for your explanations. I've only done boating and so evidently have been using mode 2 across all my Tx without realising it.
I've also been mixing and matching different makes of Rx and Tx (and crystals) on 40 so a particular make was not significant.
For 2.4Ghz it would seem the buying irequies a commitment to one manufacturer.

But I now have a better clue how to assess the market. Thanks again.

Mode 2 is throttle on the left stick (forward \ backwards) with rudder (left \ right). Mode 1 is throttle on the right stick with rudder.

The modes are generally used like this for flying RC aircraft. There are other modes 3 and 4.

This should help explain.  Just remember they are talking about airplane rudders not boat rudders lol  on a boat you can have the rudder on any channel you choose

Thanks Essex2visuvesi. The link is just what I was looking for. A picture is worth a thousand words

I tend to agree but if you are using a twin stick  tx and both sticks move in all directions, you are best sticking with rudder, whether boat or aircraft, on the throttle stick. It'll help if you ever do decide to take up planes & helis 

[essex2visuvesi]

I use a 6ch TX for my boats and have throttle on the left and rudder right.... a throwback from my RC cars days but yes it does make it harder to fly mode 2 helis and planes but you soon get used to it

or hovercraft?

Hi All,
Sorry to state the obvious on this subject but Multi Channel sorry but the correct wording is Multi Functional set (as Hugh Bright RIP of MMI used to smack me around the head over)
The Transmitter has two Gimbals both rotate 360 degrees, each gimble has two functions - vertical and horizontal each function has two end points - North and South and East and West.
That's it - How you set them up is entirely up to you!
Do not over complicate things with what everyone says you must do, there is no must do.
Mode 1 simply means that the right gimble in North and South mode is a Throttle for aircraft and is ratcheted whilst Mode 2 on the left Gimble in North and South is for other types of models witch sometimes is throttle and and has - sometimes a ratchet. This will vary from manufacturer to manufacturer of course.
At the end of the day - don't worry about - just enjoy it.
Regards to all
Graham
