does anyone know of a company that build's transmitters..

atm im building a MS loyal class, how ever after thats done i want to build the M.V calestine by deans marine....

i want a normai 2 stick for the throttle and rudder but i also want to add another 4 sticks because i want to add 2 bow thrusters and 2 stern thursters.

anyone have any info or suggestions ?

kind regards
Dan

You can buy sticks and if you take the guts of a commercial transmitter and a box from Maplin you can build any layout you wish.

Robbe F14 and similar series are made up from a plugable set of controls and you can buy spares from their website.

If you dismantle a TX bear in mind that some of the secondary channels may not be proportional, just on and off. In some radios the on/off channels can be made proportional but not in all cases according to previous posts on Mayhem.

Good point thats why I mentioned the Robbe system as all of its channels are proportional  and or switched.

Turborix has 2 pots as well as 4 stick directions and is very cheap, but the pot functions might be specialised for helis. I'll check it.

I'm looking at a similar question over tx's. I want to build tx's that are significantly smaller than the traditional breeze block, say around the size of the Picoo-z helicopter IR box. There's no problem with the radio - 2.4 Ghz 'hack' kits from Frfly and others make it very straightforward. The problem is that the NE5044 PPM encoder chip, heart of many prehistoric radios, has not been commercially available for years and the 'toy' tx's use digital encoding that's not suitable for 2.4Ghz rx's.

Does anyone know a solution to this in the form of a microcontroller based encoder chip? The NE5044 had 6 analogue inputs and would make a very simple wiring job along with the 2.4Ghz hack kit. Of course behind every bush lies a CE inspector...

turborix (search the forum for more info, its been done to death!) or its other trading name of flysky, if you get the 6 channel set, there are a further 2 proportional knobs. I use this set for a number of boats, just bought another, £12.00 plus £15.00 post from China,  inc transmitter, operation cd and a usb lead, as all setup is done on the pc, why people are still buying 40 and 27 meg when budget 2.4 is so cheap baffles me

It is primarily a heli set, so you have to change the throttle spring over if you want  a self centring throttle, and sort out the endpoints on the pc, when plugged into the usb you get operational graphs to set it up, once done to your liking you have a good cheap 2.4 with no worries of crystal clash at the lake

The reason people are still buying 27 & 40 is
1, some models (subs) can't work with 2.4,
2, if everyone is swapping to 2.4 all those 27 and 40 frequency's are now free meaning some people don't have to go and spend money on a                                                                     new transmitter 
3, some people are stuck in there ways using a crystal transmitter why bother swapping now, anyone whos been boating for 30-40 years will have first started with a transmitter you had to buy in a box, and build yourself,which normally cost more then the boat! ( i know as i own a transmitter that's at least 40 years old!) change change change, some just don't want to!

There's a lad on the Giant Cod forum  - Phil_g - who has been turning out pic upgrades to radios to do various things - like mixing two receivers together...

Have a look here and ask your question again.... http://www.giantcod.co.uk/forum/viewforum.php?f=15&sid=19d217d0c3837f0f7c798d1637be4398

Quite true and there's also the old adage "If it aint broke"
There was a thread on here a while back about a chap who made his own TX

Good ole days, My gear, REPtone single, Sanwa Mini-Prop (2 Function), REMCON Quantum 6 (Kit), RCME FM 35 moggies (Total home built). Not sure I could shoehorn a 2.4 giggly into the case of the RCME cos it's full of mixer and reversing things.

Seems someone in deepest, darkest Surrey still has these http://www.littlediode.com/components/NE5044_Integrated_Circuit.html?NO_COOKIE_WARNING=2&ti=4ab6d3a947757dd7bede6797c4479a8e&xid=f78a96c041e1d45235890a31df8285b3
Might be worth a phone call before you part with your dough.

And these guys sell single and dual axis stick assemblies - and probably Tx cases as well. Knock three times and ask for Martin Lewicki.

On the original post: Unfortunately Turborix doesn't allow the two pots to be linked to chanels 5&6 in 'Acro' mode. It seems they are dedicated to Heli functions, unless anyone knows different. It's a real shame. Maybe the software could be 'hacked'?

On small transmitters: (sorry for thread drift)

Dodgy Geezer - thanks to the link to the Giantcod forum.  There's some very helpful info on the Frsky hack there, but nothing addressing my exact question.  I'll post on there.

Action - thanks for the link to LittleDiode. I've sent them a query. Another company quoted min qty 100 pcs @£5.60 each, a bit over the top for me! I suspect it's the same source.

Is anyone else interested in small size tx's? The Plantraco HFX868 is about the right size to my mind, but not 2.4Ghz and not cheap either. I've used it successfully with my 1/96th picket boat, but only 3 simultaneous channels are possible on 868Mhz and the range is poor.

It seems to me that for model boat applications we could all benefit from much smaller tx's and with the 2.4Ghz hack module running at 6v and 50mA much smaller batteries are possible as well.

Hai Dan, you can make rc system very simply by using an FM wireless mike, and a FM pocket reciever.only thing that you need to change is the crystals in Rx and Tx according to your local legal limits.means operating freequency.

Hi Victorian

       REF :-   Turborix / Hobbyking / Flysky ,  6 chanel radios you mix all Chanels check out the software at 

                   http://www.sgr.info/usbradio/

 Timo2

     P.S.         Dan2010  Ref your question have look a new low cost 7 Chanel 2.4 unit at

                      http://hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=8992

                    About  £47.00 delivered UK.     RX only  £ 7.00

I use 5 and 6 in acro, for lights and a servo for a smoke unit, it was a real fiddle to get rid of the mixing for a heli, If I can I will send the folder of my set up if you want?

The point I was making was that of cost, todays technology is affordable so why ignore it, time and time again I witness a total disregard for occupied channels operating on 27 and 40 meg risking damage to models, so why buy new crysal sets when 2.4 is the same price, other than subs, it just does not make sense
