Weatronics ques
 

Hi guys,

Does anyone know if those fancy weatronics rx's will uncouple the trim when two servos are mixed?

E.G., nose wheel to rudder mix: if the the nose wheel is the master, will changing the trim on the nose wheel change the trim on the rudder if programed through the rx?

No, at least I cant SEE any way of doing this.

and in answer to 2nd Q, Yes, if adjusting the trim lever on the TX. because the receivers can't differentiate why the signal value has varied, ie because of moving the stick or moving the trim lever, both of which have exactly the same effect of varying the the final pulse width. To have a trimmable rudder OR N/S (from the TX) you would need to have 2 channels, the second driven by using a mixer and selecting " trim off" on a JR 10X because my understanding of this is that the mixer can take a signal variation from the primary channel BEFORE the effect of the modifier, the trim function. However, it should be mentioned that the neutral position of the servos, slave or master, CAN be adjusted seperately by the software of the DR.

Thats my understanding of it anyway, but pehaps the JR and Weatronics experts can chime in and correct me.

I am reinstalling the Weatronics DR in mY SM Hawk this afternoon with the new software so I'll take a look and see if there is anything to change this view.

Rafael,
Simple answer is NO. It is going to follow the commands from the radio, if the trim is linked the RX will pass that data. If you do not desire this feature you must disable the trim function in the mix. You can program the mix in the RX instead of the radio but it will follow the trim position from the radio. I typically set this up just as described, Nose on rudder channel, rudder mixed with trim function disabled through the radio.

RE: Weatronics ques
 

That is the way I did mine. Rudder is one channel! Nose wheel on another! I have rudder as master nose as slave! I put the nose wheel trim on a dial so I can adjust as needed! Dial does not affect the rudder trim! Rudder trim will affect both but once rudder is trimmed simply re-adjust nose with the dial. Futaba 14 mz transmitter! Works perfect for me! I love this receiver!!

RE: Weatronics ques
 

What I dont like about this setup is if you bump the dial, your nose is now out of trim. If you use the Rudder channel for the NG and slave the rudder (trim option off) you can then use the trim lever to adjust NG tracking and rudder stays in trim.
Just my .02

RE: Weatronics ques
 

Better still, perhaps, is to use the subtrim as N/S, once set, really shouldnt need adjustment (or rudder for that matter !)

Weatronics D/R now set up in the Hawk for some fun next week, this really is a superbly useful device, particularly the data logging function.

Regards, David Gladwin.

RE: Weatronics ques
 

Todd,
I may try that but with the 14 mz the dial recesses after adjusting and you can't turn it when it is recessed! Looks like there are a lot of ways to accomplish the same thing!!

RE: Weatronics ques
 

Todd, for your own edification, your solution is only manageable on Futaba Radios. On the JR series, the typical nose wheel steering channel is a 1/2 rate channel, and is generally though unacceptable for a primary flight control surface.

RE: Weatronics ques
 

Darn I totally lost this thread? I wondered what had happened to it!!:)

Thanks for all the input guys. I was hoping that by some magical way the rx would create more channels!

In an airplane with smoke and an airbrake, mixing the rudder and adding crow will use 11 channels!!:(

Oh well. I guess I'll have to stick to my anemic 10 channel 10x!!:D

I love you guys...

Raf

RE: Weatronics ques
 

Hmmm, Futaba user myself. Dont have much experience with the JR 10X. How many of the channels provided are half rate? On the 9Z all but ch9 are full rate.

RE: Weatronics ques
 

10x. All 10 channels are proportional. At least on my 10x.

Raf

RE: Weatronics ques
 

dont feel so bad
i am more confused than you when it comes to setting up my 9z with basic mixing, rates, etc, which I still need to learn. perhaps I should read the book sometime. any website that explains mixing functions, etc on futaba 9z?

RE: Weatronics ques
 

I seem to remember reading that on a JR 10 system, that all 10 channels are proportional, but channels 9-10 are updated at a reduced rate. It is not really noticed unless you use servos on channels 9 and 10 with servos on channels 1-8. As long as you keep all mixes on 1-8 or 9-10, you are okay. Just use servos on channels 1-8 for all primary control functions. Use 9-10 for other functions such as gear, brakes, etc. You can mix functions, as long as the ones on 9-10 are not a problem being updated at a lower rate.
I do not think there is an issue with the 9 channel systems.
Can anybody confirm these items?

RE: Weatronics ques
 

Correct, ch 9 and 10 are updated at a lower rate on the JR 10X....

Where is JR's 18 channel 2.4Ghz radio???? We all need it!!!

RE: Weatronics ques
 

Whoa! Multiplex and Graupner make 4 different 12-channel radios with all 12 channels having equal resolution and refresh rates, and were doing so a decade before Futaba made the 14MZ.
As far as I can tell from Weatronics spec, we can't use the Weatronics because they don't have enough channels to match our 12 channel tx!!!

I am pretty sure you have got the JR 10 wrong. Its channels 9 and 10 update at the same rate, but they are 9 bit 512-step rather than the 10 bit 1024-steps of channels 1 to 8, so they are simply of marginally lower resolution.

RE: Weatronics ques
 

Weatronic do have a 12 chanel rx

12-26 R GPS

RE: Weatronics ques
 

No you don't have to continue to be limited by a 10 channel transmitter... I've got two of them but they are used only when 10 or fewer channels will do. I have been flying the 14MZ for well over a year now, superb locked on range checks, and flawless flight performance.

I have read the threads about problems with the 14MZ and from what I can deduce those problems seem to relate more to user induced issues ... similar to the problems I've read and heard about but never experienced.... with the Spread Spectrum radio.

The Weatronics website does not mention a 12 channel rx, it only lists 8 and 10 channel rx
http://www.weatronic.com/cms/index.p...d=27&Itemid=51

Come to think of it though, since the rx will do all the splitting between servos and individual servo reversing and travel, the system doesn't need all the channels, most of my jets would work from 7 or 8 channels with the Weatronic splitting it out to the required number of servos. What a Pity the 8 channel Weatronic doesn't have GPS!

Harry

RE: Weatronics ques
 

hehe, I can see your point Harry.

the 12-26 is not listed on their site.........but it is in their servo config program :D

RE: Weatronics ques
 

Thx Harry for correcting my use of the words. I knew it was 512 vs 1024, but I got lazy with my English..oh, American!!!

I found that out when long time ago I used two channels for elev servos, one was on ch 9 or 10 , it moved differently than the other half. I called JR and they informed me of the facts....

RE: Weatronics ques
 

I am in the process of trying to select which version of the weatronic I am going to use on my F18. The one question I have is; by using buffered servos extension wires will it affect any outcome or?

I know if I use a buffered extension on my digital hitec servos, the programmer will not allow certian things to be done.

Any comments?

Paul

RE: Weatronics ques
 

Can't offer any advice on use of Hitec servos (but dont see why you should have any problem, all the programming is done withing the receiver which then supplies the, modified, output signal to the servos) but I strongly recommend the use of the Weatronics WITH a GPS as it allows much more meaningful and detailed 3D data readouts.

The latest firmware update allows selection of digital or analogue servos, futher refining servo performance.

Regards,

David Gladwin.

RE: Weatronics ques
 

thanks David for your reply, but then that last statment you made makes me still think about the buffered extension

"The latest firmware update allows selection of digital or analogue servos, futher refining servo performance"

If I have a buffered extension wire inline to a digital servo, would it make any problems? Is the new firmware in the weatronic just to be that more precise in programming it, or will it change anything that the westronic will output to the servo. If it were just analog I wouldn't worry about it at all.

The reason I ask is that I like using buffered extensions over clamp on mags, maybe overkill, but has worked for me for years without any problems so far.

I am leaning toward the full blown version with gps, because of the extras that it brings to see all the data afterwards.

thanks
Paul

RE: Weatronics ques
 

No you don't have to stick with just 10 channels Futaba has a good 12 channel and a great 14 channel... today. Keep in mind you can't take anything with you... it's just money!
Lee

RE: Weatronics ques
 

rav.....i have a perfect solution....and its cheap......go over to your buddy ehabs house....than get him really drunk....when hes not looking or has to go to the bathroom...steal his 14mz....than spray paint the 14 black ...than stick spectrum decals on altered 14.....make sure to give ehab a hug to make him feel better about his stolen radio.....also deny any involvement with the missing radios......see you dont need advice on thi forum!!!!!kelly

RE: Weatronics ques
 

Sorry, Paul, should have covered that. With the DR you dont need ANY additions to your cables , the DR takes care of that but Weatronic recommends you use stranded, twisted, cables. Intairco (www.intairco.net) supplies just such cables with gold connectors at a very reasonable price. You will be amazed at just what this receiver can do !

David Gladwin.

RE: Weatronics ques
 

Thanks Dave for clearing that up. I was reading the manual from oline, the installation determines which axis the gyro will work on, looks like to me if I want the rudder or nose wheel controlled, I have to buy an external gyro and connect it to the weatronic, correct?

Paul

RE: Weatronics ques
 

Paul,
I think you can put it 'vertically' and it will work on the nose or rudder. Not sure how practical that is[X(]
Edgar

RE: Weatronics ques
 

Yes, to control the yaw axis with the DR gyro function you will have to mount it vertically so an external gyro may be best, and thats what I am doing on my Hawks. I mentioned this to the Weatronics team at Jet Power and I dont think my comments went unheeded. Watch for future developments.
Regards, David Gladwin.

RE: Weatronics ques
 

thanks guys, looks like I am all questioned out on this topic for now, lol :D

I still have time to wait for purchasing the weatronic, but I will keep an eye out for updates.

Paul :)

RE: Weatronics ques
 

I am installing a weatronic in my boomer XL, How are you guys running the airiels, do I need to use a whip on one, I don't like the look of them. The way I have it at the moment is one running one side to the front and the other on the other side running to the back finishing alongside the engine. Should this be ok or should i have a small whip on the nose.

RE: Weatronics ques
 

I read the manual, it states for best performance is to have one on extenal whip and other run along iniside length of fuse, if excess carbon is used, then to run thru one wing.

Paul :)

RE: Weatronics ques
 

I would definetly use a whip on one of the antennas assuming that you use 35 mhz.

72 mhz have better range from what I'm told.
Heared a story about the JWM in UK some years ago when the Americans had to put 35 mhz receivers in their planes and still kept the antenna inside the plane as I understand is normal in the US.
The story said there was a lot of range/ interference issues.

That being said, on the two flights I had with the Lightning/ Weatronic this weekend, none of areials was ever low on signal at any point during the flights. One of them is located inside the fuse while the other is on a whip....

What I saw was that when one of the antennas had a lower signal, the other one was usually stronger at the same time. It still kept antenna 1 as "used" at all times during the flights as the signal was alway good enough.

RE: Weatronics ques
 

I have a Weatronics in my FLASH on 72mhz and it has been rock solid. I have one antennae using a Deans two piece base loaded whip mounted in front of the canopy and the other run back through the fuselage on the opposite side of the wiring going to the turbine. So far, with about 25 flights it has never had any loss of signal. Always uses # 1 antennae, which is the base loaded one, and no frame loss on the # 2 either!! I am sold on these receivers! They seem pricy but when you consider what is in them, 2 receivers, redundant power supply, voltage regulator, gyro and GPS! Install the same things individually and see what that total is! For me, just 2 of the Futab G3 receivers is more than the cost of the Weatronics!!

RE: Weatronics ques
 

I have another question, I sent it off to weatronic info email as well,

"I have a question about the DR, if I want to put to servos on the same channel, eg; each one will do a retract valve each, but one is for doors and the other is for the retracts, can I change or delay the time of each servo is activated on the same channel?"


this would eliminate the need for any electronic timming devices, yes?

Paul :)

RE: Weatronics ques
 

NO, not in current format but it may come in time. ( but lets see if weatronics proves me wrong !) It doesnt make tea either , well not yet !

Regards,

David Gladwin

RE: Weatronics ques
 

Paul can you use the hitec servo programming feature to slow down one of the servos one of the servos to make it work?
Otherwise you can do a mechanical setup that connect a slow servo to both valves. Saw it in a recent RCJett magazine article about the SM F-16.

RE: Weatronics ques
 

Hi Egdar, I could but they are 85mg non digitals, i am using them on UP#1 valves, I have a mini Hobby Gear & Door computer, This will work fine, but thought that the weatronic might take of it also, still not heard from them yet. I could aslo use a UP #3 and slow down the servo in the 9zcwII programming, but....... don't have one.

Paul :)

RE: Weatronics ques
 

Paul:

The Weatronic guys are working on a intergrated gear door sequencer function with the receiver. If we are lucky, we will be able to uppgrade the software to get in in to existing receivers.

Have a look [link=http://www.rcuniverse.com/forum/fb.asp?m=5553687]here[/link] to se what Alwin from Weatronic wrote to me....

RE: Weatronics ques
 

thanks, I was reading that thread the other day, man got to read everyone to stay on top of things. I still don't have mine yet. got some other ventures to finsh up first. but great to hear about the new 12 channel upgrade, I hope they can do it in PCM as well.

Lets see, maybe they can use the rx using the gps input to return the model to base, hmmmmm...... imagine that one, autopilted landing feature, could these gps units be that precise? now that would get costly

Paul :)
