Stephen Belshaw Posted November 30, 2018 Share Posted November 30, 2018 In my ongoing learning curve with the X9D and OpenTx I spent the whole of the day setting up a mix to give me spoilerons and camber. I finally achieved the happy state of the control surfaces moving as I wanted them to, however I cannot get as much throw on the spoilerons as I would like and when they are at their max there is no movement left for up aileron. Here are pictures of the servo at neutral, at maximum when spoilerons are engaged and a view of the max spoileron deflection I have managed to achieve. I have set the spoileron mix at 100% weight, the ailerons are less than that. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted November 30, 2018 Share Posted November 30, 2018 Stephen, not an Open Tx expert, but what you describe is quite normal for spoilerons, what you need to happen when you have the ailerons raised is for the down going movement to increase to ensure good roll control. If you have limited the down going travel to provide some aileron differential you want to set it up so that the differential is reduced as the spoilerons are deployed, Quote Link to comment Share on other sites More sharing options...
Stephen Belshaw Posted November 30, 2018 Author Share Posted November 30, 2018 Frank, do I take it that with spoilerons deployed, down aileron but no up aileron at all is ok? Feeding in extra down when spoilerons are operational presents me with a further programming puzzle! I'd still like to know why the servo travel is so little, way less than circa forty degress each way ............ Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted November 30, 2018 Share Posted November 30, 2018 Does the Taranis have a maximum servo travel setting? Many systems can limit the travel to protect servos/linkages trying to exceed a preset limit as a result of combining mixes. Quote Link to comment Share on other sites More sharing options...
Stephen Belshaw Posted November 30, 2018 Author Share Posted November 30, 2018 Martin, yes the Taranis does but I should still have 100% (of what I'm not sure) but there is no way I have the normal amount of movement on the servo - I'd guess at around 20 degrees. I was hoping someone may know of a "hidden switch" I need to flip to restore normal service as it were ....... Quote Link to comment Share on other sites More sharing options...
PatMc Posted November 30, 2018 Share Posted November 30, 2018 Stephen, normal 100% servo travel with the Taranis is greater than when using most other Tx's & can be increased further if required. What max travel is showing on the screen of the "Channel Monitor" page when you mave the stick from one side to the other ? PS have you done a calibration routine ?

Bob Smitham Posted November 30, 2018 Share Posted November 30, 2018 hiya Stephen.I have been using a Taranis from scratch for 3 years my first and only TX.Every model I have set up requires googling .Admittedly theses models were F/C equipped quads quads and flying wings.I'm currently going for the pure RX planks too improve my flying skiils. This clip from painless360's channel describes the method for Flap position.As far as I know the same princile applies for all servo travel.Painless360's channel is wonderfully presented and very clear.He covers most Taranis basics. https://www.youtube.com/watch?v=ykKcfPDjp7U Quote Link to comment Share on other sites More sharing options...
Stephen Belshaw Posted November 30, 2018 Author Share Posted November 30, 2018 PatMc, well looking at the channel monitor it's a lot less than 100% (see attached images), but not sure how to amend that?? Yes, I did a calibration fairly early on. Bob, I have spent hours watching Painless360 videos - all very good but all this information takes, for me anyway, ages to absorb!

Stephen Belshaw Posted November 30, 2018 Author Share Posted November 30, 2018 Here are my input, output and mixer settings: Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted November 30, 2018 Share Posted November 30, 2018 Stephen on the outputs screen you have Ch2 limited to 15.7% in one direction. So the servo can never go beyond that. Quote Link to comment Share on other sites More sharing options...
flight1 Posted November 30, 2018 Share Posted November 30, 2018 have you seen rc-soar very informative see about servo calibration and you can download setups for different glider types which shows how to do it and you can then customize to suit your own needs. this site is a must read and very helpfull Quote Link to comment Share on other sites More sharing options...
Stephen Belshaw Posted November 30, 2018 Author Share Posted November 30, 2018 Chris, I guess I have set them at that to give me the amount of aileron movement I want - 15mm up and 7mm down. Maybe I'm going about this the wrong way - a little knowledge is dangerous! If I set them to 100% how do I get the range of movement I need whilst retaing the capability for full throw when I need it on the spoilerons? Thanks flight1, I'll take a look over there.

Chris Bott - Moderator Posted November 30, 2018 Share Posted November 30, 2018 Yep, the outputs page is just what it says on the tin. You're setting the overall parameters for an individual channel output, no matter what all the mixes do. To limit just one of the controls that are mixed into that output, you need to do that in the particular mix line. Or, you could do it in the inputs page.

Frank Skilbeck Posted November 30, 2018 Share Posted November 30, 2018 Stephen, a lot of Open Tx glider guiders use this site for advise and set ups Quote Link to comment Share on other sites More sharing options...
PatMc Posted November 30, 2018 Share Posted November 30, 2018 Stephen, here are a couple of principles I apply when setting up spoilerons that you might find helpful. To get the most combined aileron+spoiler travel as well as the most applied torque over any part of this travel it would be best if the servos are moved over their full available end to end limits. In the "Model Setup" page scroll down to "Extended Limits" & press enter. This will allow the outputs to be increased up to 150%. Before starting any spoiIeron/camber mix I set the aileron servos outputs to a little under the max % that brings the travel to it's end point, obviously the same % each way for both servos. I use a switch to enable landing mode that then allows a slider to control the spoiler action. The landing mode also switches on a coupled aileron - rudder mix [about 50%] to compensate for any loss of aileron authority caused by the spoiler action during the landing.

Stephen Belshaw Posted December 1, 2018 Author Share Posted December 1, 2018 An update to say all is working as it should now, thanks to Chris who pointed out the limits on the output side - these are now set at 120% so plenty of movement! It seems obvious in hindsight, but these things are always easy when you know how! With the confidence boost that programming a mix has given me I took a trip in to the bowels of OpenTx and removed the annoying "Welcome to" voice that now no longer irritates the hell out of me every time I switch the radio on!

Peter Christy Posted December 1, 2018 Share Posted December 1, 2018 I replaced the voice package on mine with the Amber one. Makes me feel much better when I switch it on, now! -- Pete Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted December 1, 2018 Share Posted December 1, 2018 Good news Stephen. It's often not easy to know what's gone wrong in a more complex setup. But thankfully that one did pop out at me. Pics of the screens was a very good idea. Quote Link to comment Share on other sites More sharing options...
Jonathan M Posted June 3, 2019 Share Posted June 3, 2019 Useful thread this as I've just started with Taranis and have encountered the same problem with spoilerons limiting aileron travel on my Middle Phase and Wot4. (Sorry however to see the pictures have gone!) Although I've got much more to learn, like setting rates on the input screen rather than on the output one as I did, and extending travels etc, I've got enough of a hang of it to get flying - and can already see how much more flexible the system is than my old Spektrum.
