Hi all
I am at the moment using 40MHz FM but now own a 2.4g set which I have found to be easy to use in that I turn up at the lake and switch on then play.
My question is I have two tugs that require multi channels
one has 11 channels in operation the other has 9
I have seen 2.4g with 8 or 9 but is it possible to extend the radio set to house modules like those I currently use in my Futaba FX18



It seems a very expensive option to purchase a muti-channel radio that would then be limited.
Yes I could stop adding to the tug but that is part of the fun.
Also I have been able to use two boats on the same transmitter at the same time
= boat 1 on channels 1 to 5
= boat 2 on channels 7 to 12 (this boat has rec and multi-prop module)
I know this will not be possible on the 2.4g as the radio will only bind to one rec.

Can or will it be possible to extend the 2.4g systems or have I got to stay on FM

You can bind as many Recs to a single Tx as you want,I have 6 on one Tx.......of course, trying to use them all together at the same time would be interesting to say the least!

I have 2 rec and they are both 'bound' to the same transmitter but I cant get the two to arm up at the same time which is where I think the safeness of the 2.4 is so good. (but in my case annoying)
My biggest question is can you extend the channels on these radios or will it be a case of if I want more channels I have to get a bigger radio?

[essex2visuvesi]

some of the spektrum models will not allow you to operate more than one RX at a time as it handshakes with the RX and then switches to the correct model memory.... again a very useful feature if you have your TX setup for more than one model

Can you not use something like Action's P62?

Generally sets which go beyond 8-channels are using special methods to stretch past the PPM standard e.g. digital control methods which tend to be proprietary.

2.4 ghz sets with lots of channels are available, but they're not at the cheap end of the scale.

You may want to consider trying a 2.4ghz conversion set for your FX18. These are inexpensive (about twenty quid, with a receiver) and work very well. I successfully adapted my Robbe FC16 to dual 2.4ghz and 40mhz use (I require the lower frequency for submarines) witha Corona kit. I would expect the set to function perfectly using the add-on adapter modules for channel expansion, although I don't actually use these.

I use two receivers simultaneously connected to a 9 channel 2.4.

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8992    ( one transmitter c/w receiver plus 2 additional receivers cost £61.22 delivered to ther U.K. from Hongkong. )

One in my lifeboat uses channels 1-4, the lifeboat house has the second receiver on 5,6 & 7 to remotely release the lifeboat down the slipway and later send the recovery wire down the slipway to magnetically attach to the lifeboat and finally another to operate the winch during remote recovery back up the slipway.

Hi
If you just want to carry out on/off switching, have a look at Hunter Systems 8 function sequence switching system (octo) or the range 433MHz short range switching systems (key fob technology).

Hi there kinmel,
I already use two rec with one transmitter though 40MHz
My 2.4 transmitter is only 6 channel so has not got enough channels to start with which is why I asked if it is possible to add modules to increase the channel amount like I have done in the FX18.

It is just to simplify things a little, so I did not have to take so many transmitters to the lake, it's either that or change the 2.4 back to 40MHz

to answer your questions,

1. the only way you can run 9 or 11 channels will be to buy a 9 or 11 channel Tx (or more - spekky do an 18 channel one for approx £550)
2. you can bind as many Rx to your Tx as you wish, as long as they're bound at the same time.


Mark.

Thanks for the answers
Oh well it looks like a lot of saving up for to be done
Or to suffer the extra stuff carried to and from the lake.
I suppose I could sell off the Futaba FX18 with the gizmo's inside..... to get some of the required money, but then there would be the need for five or six  2.4g rec's
best I don't let the wife know just how much this lot may cost

Jeti do a 2.4G module for the FX18 and a 18 ch Rx. Fitting the module is here. I have a friend using the Jeti conversion for boat use on a Multiplex radio, he is extremely satisfied.

I have a Jeti module internally in my 9C it is very good not a gitch plus instant feed back like out of range warning and low receiver battery plus gps speed temp rpm and a lot more. well worth the extra cost
