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.

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.

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!

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.

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!

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
