I am using my Weatronics 12-22R receiver in the large SM Viperjet, driving it all with a Graupner 12 channel MX24S TX.
I need more than 12 inputs to control all the servos/ ECU / lights etc. Now it is easy for most of them, for example the nose wheel can be
mixed with the rudder and unmixed when the wheels retract, lights can be mixed with retracts so the lights are on when the retracts are down and off
when the wheels are retracted. All this works well on my L39 using all the 12 positions on the tx..

But I need a channel for a smoke pump, which is turned on and off from a switch on the transmitter, is there a way to do this using an extra channel on the receiver??

So advice please...(Yes I know a TX with more channels would the answer but Graupner are running late with the MC32 and it wont be available till later this year.)

Further to my Posting, some additional details, showing where I have my servos (or channels) at present
Servo 1 throttle
Servo 2 Aileron left Servo 5 Aileron right
Servo 3 Elevator left Servo 8 Elevator right
servo 4 Rudder Servo 10 Nosewheel mixed with rudder using the Giga control
Servo 6 Flap left Servo 7 flap right
servo 9 Brake from EVSD Pro
servo 11 Retract from EVSD Pro
servo 12 ECU

channel 13 lights mixed with retracts using the gigacontrol.

Looking at these, it would appear to be possible to mix say both elevators using the gigacontrol (or the flaps), which would free one channel. But that has the disadvantage that if adjustment is needed in the field,
then I need to carry the laptop, whereas it is easy to use the servo adjust feature on the tx.


Comments please

Must restist being a smart a**e, nope can't resist

If you where using Futaba FASST system you could use the Multiprop plug in and have up too 26 proportional channels.

Sorry, but after all the interventions of every other JR and Futaba thread by best thing since sliced bread Weatronic exponants, and the supercilious you should have been using Weatronics, I could not resist this post.

Hi Ross!

After playing around with one of their 35MHz recievers, I am not much into Weatronic, but: Why the hell do you waste all your channels, if you use a device like the Weatronic that comes with internal mixing? Get your MX-24S, change a few settings and you will end up with 1 or 2 unused channels. Change it from dual elevator to single elevator. Use the internal mix-function to slave the second servo to the elevator-channel. Same with your flaps. Once the flaps are dialed in, you will never touch the servo-settings again (on the field). Now if you are still looking for a couple of free channels, you can set your transmitter to one aileron and get the settigns done via the rx. And it is possible to run the gear-valve and the brake-valve on one channel. Last question: What kind of engine do you use? I have not used two channels to operate a turbine for the last 7 years. That was after JetCat made the switch to a possible 1 channel operation. So what was your problem again?

I hope this helps. I am just dialing-in my Airworld L-39. 2 ailerons, 2 flaps, 2 Elevators, rudder, steering, ECU, ligths, speedbrakes, smoker, gear, gear-doors, brakes. ANd the door-sequencer is programmed in the tx....


Best regards,

David

Ross, David is correct, you seem to be wasting Tx channels doing jobs that the Weatronic has been designed to do. Ask why it has 22 outputs when no tx has 22 channels to drive them individually! Only transmit one elevator, one aileron, one flap and so on, and tell the Wea Rx to map it to however many sockets you need to drive. Any adjustments to centring and travel in order to make the control surfaces match one another can be done at the Rx by GigaControl. You only need 9 Tx channels to do all that you need, though I prefer to keep the nose steering on a separate channel as it is much easier to centre the steering from the tx than through the rx, and that would take you up to 10 channels, well within your limit of 12. you just have to accept that taking a laptop to the field to make adjustments is one of the downsides, however I have found that if properly set up at the workshop then all field adjustments (other than altering the failsafe) can be done at the Tx.

Thanks all for the comments,
I will look at your advice in the morning. (its night down here under!!).
Re the turbine, I have standardised on Jetcat for my 80 120 and a 160 (which is on its way from Germany) for the Viperjet.
David How do I run the Jetcat on one channel?

Thanks for the advice
Best wishes have a good weekend, its b- wet down here. We had 4 months of very dry weather during the summer,
then the past 4 weeks have more than caught up on the rain we missed.

Neat gizmo, I am assuming they are slow updating and for switched channels only, or am I wrong?

I was able to use the Multiprop with my 72MHZ Weatronic receiver, using futaba 12FG. I have no tried it yet with the 2.4 version, but I guess I assume it should work.

(so maybe the ideal is Futaba + Weatronics ?)

From the news on the their next software version, it seems that they will support the multiprop feature of the 14MZ(among others). If so, that would truly be very nice !!
Imagine, 26 channels, should/would be enough for most

I am using my second weatronic, one 72mhz and one 2.4 12-22.

My advice is to suck it up and travle with the laptop. It opens up the possibilities. I have an A10 with 10 channels and 14 servos and have plenty to spare...

I was just looking at all of the data from two flights yesterday and it is quite comforting to look and see what is happening on baord that plane regarding signal strength, frames, speed, battery info, current draw etc. Not necessary for all jets but in this big bird it is a relief not to be worried if my signal is ok etc. Plus I have an audible warning if anything starts to be a problem in the air.
yes, more work to setup but still not a bad value, service is fair, Gerhard does everythin ghe can although I think he is at the mercy of supply from Germany.

Good luck, if I can help please respond here so we can share with others.

Dave

The Multiprop system works with the 14Mz and the 12FG as long as you have the latest firmware update, the Multiprop plugs into channels 11 and 12 if you use both on the 6014 with the 12 FG not sure about the 14Mz, but this means you loose 11 and 12 but gain 16 extra proportional channels, the only drawback with the extra channels is that they are not trimmable, but have all the other normal attributes, ATV, End Point, D/R etc:

Mike

P.S. forgott to mention I am using it on 2.4Ghz.

Thanks to all for your comments, they have been very helpful.
I am very gradually getting to know how to drive the gigacontrol software.
One question, is it possible via the software to set up the neutrals independently on 2 mixed servos, such as the 2 elevators and if so how do I do it?
Using the tx, it is possible to adjust the neutral position of the 2 servos together, but this means they have to be mechanically set to identical positions and this can be difficult.

Comments please

Regards have a good weekend
Ross

Yes.
From memory: got to the tab where you assign each channel to the servo socket. right-click the box representing the servo you want to adjust. You will get line chart representing the way the servo will respond tp the signal. Click 'move curve' and adjust up or down as desired to move the neutral.

Ross,
Virtually everything is possible with the Gigacontrol software. Even complex mixers from one channel to other ones.
Take some time to read both user manuals for the 35/72 Mhz units and 2.4 units. You won't regret the time spent.

You can offset the neutral for each servo by moving the whole curve.

A well programmed 12-22 units is nearly impossible to saturate. However the multiplex functions from Futaba/Graupner will soon be supported with will potentially increase the inputs to 26 channels an outputs to 36 servos ( 44 with the 12-30 unit ).

Oli,
Thanks for the comments, yes downloading and reading the 35/72 manual has helped.
Also what is helping I was confusing the Graupner tx setup with the Weatronics, ie on the MX24S setup it says to use position 3 on the tx and 8 for the elevators,
I am now realising with the Gigacontrol software, this is not necessary, So I will have to go back and recheck my setup.

Now all I need is a small laptop for the field, maybe something smal like the Ipad, but which runs windows.

Fly safely

Best wishes to all
Ross

Hi All,
I am starting to get really upset about Weatronics, I have spent a lot of money with their equipment, and I WAS keen to spend more, but when I need support
Alwin is not available, he is with the taxman, Christoff cant help, nobody answers emails,(trying to buy more items) and now nobody answers the phones.
What a way to run a company!!!!!!!!!!!!!!!!!!!!!! Good equipment **** service..............
Talking to their Australian agent they are also seriously considering it is not worth the problem of trying to get information.

Maybe Futaba would be better.

Ross

Well the problem is that Alwin is in charge the development of the products. They actually have no one who is available to properly answer technical questions.
Bear in mind that this is a very small company with 4 employees only.
So I guess that they are having a hard time balancing the financial risk of employing someone for customer support...

Yes But Oli, they are selling world wide and advertising hugely, and therefore they need to be able to service customers.
Yes there is a financial tradeoff BUT without support, they will rapidly lose the customer base thay have.

I want to use the equipment, but it is hopless unless I can get an answer...
Also having upgrade and not having the hardware, such as the USB hardware available is absolutely ridiculous.

ALL I need is to be able to find out how to reset my very expensive 12-22r so that it will bind to my TX again.
Then I can finish setting up the Viperjet, but without a receiver I am stuffed........
Ross

ps:Oli I have my own company and I know exactly what finance and customer srvice is all about.
