Taranis 6 Servo Glider eepe file
« on: October 21, 2013, 13:20:31 PM »
I have had my Taranis for a few weeks now and I have been slowly moving my existing models over to the new transmitter. It has gone very smoothly so far with the simpler models.

I have made an attempt at writing a program for a 6 servo glider (V-tail, 2 Ailerons, 2 Flaps) with crow braking and leading edge adjustment. I have got it to work but it is not very elegant or efficient and leaves room for improvement.

Is anyone prepared to share their program for this type of plane. I have had a look at Mike Shellim's F3F web site but have been unable to download his eepe file.

Thanks
Ian

Hi Ian, well done for on progress so far.

I have had a look at Mike Shellim's F3F web site but have been unable to download his eepe file.


Try right clicking this link, followed by 'save as'
http://www.rc-soar.com/taranis/files/MS_F3F_v1-1.eepe

If problems persist could you let me give more info - o/s, browser etc.? In the mean time, I will also try and PM you the file.

Regards
Mike

I am running Windows 7 and Internet Explorer 10. When I right click I do not get a "save as" option. If I click on the link it opens in Internet Explorer. I have tried saving the file using "save as" from the internet explorer file menu. I am able to save the file but it remains an Internet Explorer htm file rather than an eepe. I have tried renaming the file with a eepe suffix but companion does not see it within the directory.
I will send you a PM with my e-mail address. Perhaps you could e-mail the file.

Ian, the file should be on its way. In the mean time, I've wrapped the .EEPE file in a ZIP which IE10 seems to handle OK.

Thanks for your help. I have been able to download the file now that  it has been wrapped it up as a zip file. I have also printed off your excel spread sheet so I will be spending the rest of the evening going through the program attempting to understand what you have done.

Having made the effort to write my own basic version I am slowly becoming familiar with OpenTx.

Regards

Ian

After finally succeeding with the file down load I have spent this evening tweaking the various settings to  suit my model. So far I have been able to make all the adjustments I require without too many difficulties.

The program written by Mike is working very well. It is much more flexible than the program I wrote myself.

Ian, glad the setup is working for you :)

I wasn't sure how much detail to go into in the documentation, but looks like you've sussed it. That said, please feel free to email me if anything crops up.

I had my first flight this afternoon with Mikes F3F programme set up on my Taranis transmitter. I was testing it on one of my older models a Purbeck Assassin. The transition went fairly well.

I had the snap flap set too high at first but was able to reduce the travel volume in response to elevator input with the throttle trim.
In landing mode the elevator compensation for spoiler flap travel was very close to that required so I did not attempt to make any adjustment. I am not sure however how best to adjust the amount of compensation. I think I need some help here.

I have reduced the elevator throws but left full throws on the rudder.

I have also decoupled the flaps from the ailerons in landing mode by deselecting it on the aileron to flap mix.

Relief all round  :)

I am not sure however how best to adjust the amount of [spoiler] compensation. I think I need some help here.

You'll need to edit Curve 2 'SpComp'. This describes the elevator correction against spoiler input. There are 5 points, RH point corresponds to zero spoiler, and must be pegged at zero. The LH points corresponds to spoiler stick fully back, and represents your max compensation.

It's not easy to see on the Tx, but you'll see in the XLS doc that this curve is used in the spoiler input to the vtail-camber mix (CH09)

Hope this helps
Mike

I have increased the values for the points in curve 2 to 0/10/17/24/31. This has had the desired effect of slightly increasing the amount of down elevator as the flaps reach full travel.

My next task is to do a better job of setting the flaps throws. I am planning to add a temporary mixer line that will replace the existing mixes. With the mix activated I will reset the end points so that both flaps have exactly the same travel. I will then switch off the temporary mixer and balance the mid travel flap positions by tweaking Curve3

Yes, that should do it!!

Once you've got your inner (flap) surfaces balanced up and with the correct Limits, you can set the end points due to spoiler by adjusting offset and wt for the spoiler input (CH11) of the CmRoot mixer (CH08). 'offset' sets the lower end point, and 'wt' sets the total travel.

I have spent another hour this morning refining my settings. Hopefully if the current rain clears I will be able to test it out this afternoon.
It may help future users of your eepe file if you could add some simple set up instructions on the accompanying excel file. To get the best out of your program it is important that the correct step by step  sequence is followed. I have found out to my cost that you must make any adjustments at the correct point in the sequence.
Thanks for all the support you have given. My knowledge and understanding have increased considerably with your assistance.

Fair points, Ian, and thanks for the feedback. Yes, setup order is important, in particular calibrating Limits is a crucial first step.

At some stage I intend to upload a newer version, with a built-in 'calibration' mode, and proper setup notes.

I flew the Assassin again this afternoon with the Taranis.  The conditions were not ideal with the wind gusting over 40mph at times. Everything is now working as it should but I still need to do some fine tuning.
I look forward to seeing the latest version of your set up when complete.

I took the Assassin out again today for a quick lunchtime fly with the Taranis. I have now got the spoiler compensation adjusted correctly now so landing was less stress full. I reduced the rudder throws as I still had them set at 100% and I had too much travel. Conditions were not ideal with the wind off the slope so I didn't stay long. I am happy however that I am making progress.

I noticed that I have more down flap movement than up flap movement when the flaps are coupled to the ailerons. I am not sure where and how to adjust the differential/travel. The flaps get their differential from GV2 which in turn via the Custom Function comes from the rudder trim as per GV1.
Any suggestions as to how I can reduce the downward flap travel?

It depends on how you have your mixes set. If you are using separate servo/s for flaps you could reduce the weight in the mix or reduce servo throw in the servo settings.

Tom

Tom

I am using Mike Shellim's F3F setup.

If I adjust the travel limits on the servo page I will then not get full movement when I deploy crow. Adjusting the weight in the mixer will adjust the throws on both sides and I only want to reduce the downwards throw.

It looks like I am will have to set up a second custom function to set the flap differential (GV2) with different settings to those used on the ailerons (GV1)

Thanks for replying.

Sorry I  reread your original post and realised my suggestion was useless and modified it (too late)
I would need to look at the eepe file to evaluate the problem.

I have downloaded the eepe file from RCsoar and It is a very complex sett up, so it going to take me some time ( not being a glider guider ) to get to grips with it.
I' m only getting the chance to look at this very briefly in between other work and I think I have been looking at this all wrong. What flight mode do you have the problem with?
And what switches put it in that mode?

I've edited this because I believe the original content was wrong.

To solve the problem I have disabled (switched off) the custom function that sets the value of GV2 from the rudder trim. I have substituted my own values for GV2 in each flight mode instead. Due to the difference in geometry of my linkages and neutral position the flaps need a considerably more differential on the flaps than the ailerons.
If I find I need to adjust the flap differential in flight I could also reactivate it on an alternative spare trim or slider.

Glad you got something sorted. I have a reasonable understanding of Taranis programming, but that eepe was doing my head in. It seems overly complicated.

I noticed that I have more down flap movement than up flap movement when the flaps are coupled to the ailerons. I am not sure where and how to adjust the differential/travel.

Ian, just to clarify re diff, there's one master diff setting, and that's GV2. GV1 is the same as GV2 but with diff suppression. GV1 is applied to ailerons, GV2 to flaps. If everything is behaving reasonably linearly, you should get the same amount of diff on both aileron and flaps.

It could be that there's a problem either the geometry, or maybe the Limits settings, for flaps and/or ailerons. I know you've worked around the issue with your GV2 fix, but it may be worth checking that you've got a good linear setup on the flaps. In any case, a good excuse to document the setup procedure for the flaps:

  • Reset the balancing curve for the right flap (set to to 45 degree line).
  • Use your REPL trick so that the throttle stick 'passes thru' directly to the two flap servos without any mixers of trims. So now you can visualise your Limits adjustments!.
  • Go to the Limits menu
  • Make sure Limits->Sym is set to Off for the flap servos
  • Now watch the flaps and set Limits->Min and Limits->Max to the 'never-exceed' end points, i.e the furthest they can move without making expensive noises. Do this for both flap servo servos, so the travel end points match. Don't worry about stick or servo neutrals, just the end points!
  • Now, do a first cut adjustment of the servo neutrals. This is done initially without visualising. For each flap servo, set Limit->Offset so that it's the average of the min and max settings (e.g. if min = -80 and max = +20, set Limit->Offset to -30). This should not alter the end points set above. You now have a guaranteed linear response for each servo.
  • The position of the flap surfaces should now match at extremes of spoiler stick travel, but unless you're very lucky (or an incredibly accurate builder!), they will not match at the stick centre. Which brings us to the next stage...
  • Adjust the flap servo neutrals... move the throttle stick to the centre (about 16 clicks from top or bottom) and watch the flaps. Tweak the Limit->Offset values of the two servos, so that the flaps line up (they'll be at around 30 degrees of down flap, we'll correct that later). Some compromise will be necessary away from the first cut we set above, but hopefully not too much. You will then have two nicely tracking flap servos, each with reasonably linear response.
  • Finally, adjust spoiler travel in spoiler input of the CH08 (CmRoot) mixer. Adjust Offset for down flap movement, then adjust Weight so that flaps are at neutral with spoiler off. Since you have two perfectly tracking servos, both sides should match up perfectly :-)
  • (very finally, and optionally, tweak the flap balancer curve to obtain super accurate flap tracking - personally I have not needed to tweak this on my Sting)

The aileron input should now be working over a linear portion of the flap travel, and so your flaps should have the correct diff as dialled in on your rudder trim.

Thanks for your very comprehensive reply. It looks like I will be spending a cold night in the workshop going back to basics on the flap set up. I followed some of the steps you have described when I first set up the flaps but missed one or two critical ones. The good news is that each time I mess something up my knowledge and understanding increases.
I will let you know how I get on later.

I followed the instructions until I got to bullet 9 where I got confused and lost for a few minutes.

It may be worth including on the instructions that you need to switch off the temporary mixer line on the throttle input at this point.

After I setting the flap travel and neutral position I found that I had to increase the offset in the second mixer line on Channel 11 when I switched out of Landing Mode into Normal mode. The flaps were not at the neutral position in the other flight modes.

I now need to reactivate the Custom Function on GV2 to restore the adjustment of the differential on the flaps.

Ian, in addition to omitting to disable REPL, I slipped up with the wording in bullet point 9. This would account for the problem you had with the flap neutrals changing as you switched in/out of Landing mode. (I did in fact correct the wording but too late for you to pick it up. Doh!)

Anyway bullet point 9 should read:

"Finally, adjust spoiler travel in spoiler input (CH11) of the CH08 (CmRoot) mixer. Adjust Offset for down flap movement, then adjust Weight so that flaps are at neutral with spoiler off."

Mixer CH11 (Splr) should not be altered, so best to restore the weight of both inputs at 100 and the offsets at zero as per Excel sheet.

That should resolve the issue, so you can tweak flap neutrals with just one adjustment, and it's also necessary for diff to work properly.

I have had another go this morning with the revised instructions and I seem to have everything working correctly.
The spoiler movement is even on both sides through the travel range
The neutral setting is constant in all flight modes
The uneven flap movement when linked to the ailerons is now resolved. It now mirrors the ailerons with correct differential adjustment.
I took me about 5mins rather than the hour or so last night.
If the rain showers hold off I will pop up to the hill behind my house to try it out.

Thanks for all your help.

  • (very finally, and optionally, tweak the flap balancer curve to obtain super accurate flap tracking - personally I have not needed to tweak this on my Sting)

The aileron input should now be working over a linear portion of the flap travel, and so your flaps should have the correct diff as dialled in on your rudder trim.

why would you want the same differential on the flaps and ailerons, and not the ability to alter them independently? Yes the same differential is a good starting place but clearly on some models it benefits to change the settings a bit.

 Things have moved on from the p4000. On a lowly hitec radio you can adjust the aileron and flap differential for each of the 8 flight modes (and have in flight adjustments).  If the setup ties the aileron differential to the flap differential, I  would call that the issue, to be honest.

say you had an f3j model setup for competition landings, you are quite likely to have flaps that move more down than up in response to servo movements (this is the case with my Xplorer 2).

I don't believe in flight adjustments are very important for differential to be honest. Adverse yaw effects are obviously highly speed dependent. I prefer to use flight modes to match the speed of the model and have the differential and aileron to rudder mix set accordingly.  to my mind proper adjustments of all settings is a lot more important that making a complex setup so you can adjust things in flight.

btw I use 5 gvars in my setup.

1) aileron differential
2) aileron travel
3) flap travel (as aileron)
4) flap differential
5) rudder to elevator.

That takes care of all adverse yaw settings in all flight modes, including launch which has 100 differential and no aileron to flap mix.
You have to use mixer lines or stick settings to alter elevator. Shame you can change more settings by default in the taranis.

Remember this is specifically an F3F setup - we don't usually use much aileron to flap mixing, if any. IMO, as long as diff is measurably the same across all surfaces, that's usually fine, no desperate need for a separate flap diff adjustment.

Personally I like to be able to adjust diff in the air when trimming out a new model. Diff, snapflap vol and snapflap expo are IMO key adjustments. It would  be nice to adjust more stuff like aileron to rudder coupling, elevator movement, aileron movement, and 101 other things, but we're limited by the number of widgets. It would be nice if FrSky would cotton on to the fact that being able to do all this trimming stuff in flight is one of the distinguishing features of OpenTx, and provide us with more knobs and sliders to make use of it.

I wasn't aware aileron to flap mixing was in some way unusual in f3f. I certainly use it on my slope models.

I don't consider "snap flap expo" very important compared to tuning the CG and elevator travel. You can fly well with no snap flap at all if you set up the model nicely.  I find it rather incredulous if you are saying snap flap expo is a vital setting. I don't use it at all and my models fly pretty well.

yes it's nice to be able to adjust all settings in the air with a NEW model, but how often do you buy a new model?  Long term you want a setup that can be adjusted to suit the model and task at hand.  Personally I attached very little importance to in flight adjustments.  there's simply too many settings that can be adjusted.  I have been flying the same f3b model for 2 years and I don't find I want to adjust settings like differential very much any more. 

From my understanding frsky itself has very little influence on the direction of the software as this still an open source project. 

I think if you are starting with the taranis, not coming from a p4000 or similar, you are better off going for a more simple setup.

Before downloading Mike's file I had a go on my own to set the model from scratch. The program I came up with worked but was not very elegant or efficient. I think the program developed by Mike is very logical and allows adjustment of the most  important variables.  When combined with some set up instructions I think most Taranis owners will be able to set up their 6 servo gliders with this program.

Once again many thanks to Mike for sharing his set up.

Quite a few F3F pilots experiment with snap flap curves, and I'm sure more pilots would if it was easy. The problem is that it's tiresome to fiddle with curves on the field. With the Taranis, for the sake of a few mixer lines, it's easy to give the pilot full control over expo  so why not? The Sting definitely benefits from a little negative expo.

I'm intending to include this in the next version of my setup, along with a calibration flight mode for visualising servo limits.

BTW, Kev Newton has written a piece "How to set up a racing glider" which discusses all these adjustments - diff, snapflap and snapflap curves. Well worth a read.

I have had another go this morning with the revised instructions and I seem to have everything working correctly...

Excellent - glad it's working OK now!

In case you haven't already noticed Mike Shellim has loaded up a new version of his 6 servo glider on his website. Www.rc-soar.com.
I downloaded a copy and set up my Whisper yesterday without incident. Mike has included an excellent set of instructions.
The set up includes a calibration mode and voice announcements for flight modes. He has also left some channels open for addition of an electric motor or tow release.

This question is mainly addressed to Mike. You mentioned in the comments on your blog ‘C9X can be a bit pesky when asked to move mixers around, but there are some tricks to ease the process’. I am not at the stage of asking for specific help (yet!) as I have not started looking at it in detail. My intention in C9X was to move the mixes from channels 1 -8 to say channels 22 and above then move them back in the order I want in channels 1-8. I seem to be able to cut and paste only one mix at a time which is a bit time consuming but no problem. I would then check the ‘higher mixes’ are pointing at the correct 'servo' channels by checking against the original. Would the above approach be ok or is there a better way?

Hi Ian,

An easier way (in terms of the C9X user interface) is to make a copy of the model in the same eeprom file. Open both the orig and the copy, each in their own window. Then in the original model's window, delete the channels and mixer lines which you want to re-order. Then, from the copy's window, drag and drop the relevant mixers back into the original model, but in the right order.

Doing a cross- or T- tail conversion will be a question of moving the VeeCm mixer to your elevator servo channel and the VeeAlt mixer to your Rudder servo channel. Fortunately these mixers aren't referenced elsewhere so that should be all you need to do. Oh, just one other thing, when you copy mixers from one model for another, C9X does not copy the channel name - you have to do this yourself, in the Limits menu.

Will go through the steps tomorrow in case I've overlooked something.

Regards
Mike

Brilliant Mike, thanks, dragging and dropping between two screens as you suggest is a lot better. I have been out all evening but just spent 15 minutes or so moving things around to match the channel order of the JR, things seem to be working on C9X, the ailerons, elevator, flaps and rudder seem to be doing what I expect. It’s a bit late now but tomorrow I need to re-check everything and follow your set-up instructions with the program in the Taranis.

Ian, just had another look reordering the main channels for JR + converting to cross tail, and this sequence works well:

  • Copy model M1 to model M2
  • Delete all the servo channels in M1 that are going to be changed or are no longer needed.
  • In the M1->LIMITS screen, rename the channels which are about to be altered, to reflect their usage after the change. For channels which are no longer needed (e.g. VeeCm and VeeAlt), just delete the names - C9X will substitute the channel numbers automatically.
  • Drag the necessary mixer lines from M2 into the appropriate slots in M1.

Step 3 is the critical bit as it's very easy to get confused otherwise  ??? Also in the mixer list in C9X I always check "Show channel names in mixes", makes it easier to see what's going on.

Thanks Mike, I have had a quick go at this but I am not sure I have done the right thing. Using my re-ordered channels from last night, in the Limits menu I deleted VeeAlt & VeeCm and these were replaced by ch 12 & 13 as you say. In the Mixes I changed the channel names to Elev & Rudd however, I noticed in these mixes the names VeeAlt & VeeCm were still there so I changed these to RudIn and EleIn.  If I have done this wrong I will start again tomorrow and follow your new instructions to the letter.
BTW when I was checking on C9X  last night’s channel re-ordering earlier, I noticed a possible minor error in the spread sheet under Flight Modes, in FM4 ‘switch B’ seems to be referred to as ‘switch F’.

Hi Ian, thanks for the heads up re switch reference.

Rather than try to explain the steps for creating a X tail version, it is actually easier to just provide one, so the EEPE file now contains two versions one V-tail and one Cross- or T-tail. Hopefully all that is needed is to swap round the servo channels as per previous instructions, but if you have any probs let me know the servo assignments and I can PM you a customised version. The documentation has also been amended to include the X-tail version.

Thanks Mike, this looks just the job, I will have a look later this evening. I am not expecting any problems with this new EEPE as I changed the channel order no problem on Monday following your method. Hopefully if I get an early evening free, I can transfer it to the Tx and go through the set-up and give it a try over the weekend, wind direction and strength permitting!
