is this virtually possible?

I've been clicking away at some examples and doing some experiments with the virtual channel / trim switches stuff and I will cheerfully admit that it just won't sink in.

So I ask if what I am aiming to eventually accomplish is even possible - so far I've tried things that made no sense and didn't expect to work, naturally they did not:

I would like to set it up so that the aileron stick operates normally, say even with rates selected by FMODE 0, 1 2 as many of the models I have come across do, and add to the AIL channel the idea that a trim switch would override any stick input and provide max aileron when pressed up and min aileron when pressed down.

I would do the same for elevator and rudder.

I don't need a fish, just describe it so I can find my way. Or tell me it isn't possible.

As for whether it is such a good idea as I think, I am willing to hear your opinion(s), but I'd like to try this out. Also it seemed like a good exercise.

I think it is possible i set up my jjrc1000a to do flips and rolls with the trim buttons..If i remember correctly i used virtual channels then mixed them to the Aileron and Elevator so when pressing the trim it applied full Aileron/Elevator as well as activated the flip channel..

I awoke in the middle of the night with an idea. Went back to sleep.

Now after much button pressing I have something that works. I think if I continue experimenting I can improve my solution - right now I am needing two virtual channels to accomplish my min/max idea on just the elevator.

Old fashioned: it will be easier to do the rudder and aileron using the text file I can examine and edit. Many of the elements and syntax don't quite seem to make sense, but it is what it is and I expect slavish copying and competent modification will allow progress, as it has with simpler things I have managed.

I am sure when I am all done it will be intuitively obvious and simple.

Thank you! This is a help indeed.

At a glance, it appears you also needed two (or at least implemented your functions with two) virtual channels for each of aileron and elevator.

But the text of your use of the virtual mechanism is simpler, meaning I went around a few corners butt0n-pressing my way to a solution that I mightn't have needed to.

Slowly the light dawns…

Not only is this possible, but it's easy.

If you're not sure something can be done, it's probably easier to try it with a normal switch first. After all, one of the beauties of deviation is that any switch can be used for any function, including replacing any real switch with a virtual switch. Or a channel output being a logical switch.

So, first question - can we have a switch that forces a channel to a specific value? Answer: yes. There's even a feature for that - channel safety. In the channel editor on the list of mixers, you can select the channel name to get to minimum, maximum, scale, reverse, etc. In particular, you can set a "Safety switch" and "Safety value". Whenever the Safety switch is on, the channel output will be the Safety value. This is normally used for throttle hold, but since it's available for any channel, it works for your use case as well. I use this to emulate the Blade "Panic switch" on models that don't have one: it sets the flight mode channel to the most stable mode with auto-leveling and the cyclic sticks to zero so it auto-levels.

Now all you need is a virtual switch, and instructions for that are in the manual.

Thank you for your informative and encouraging remarks. In addition to experimenting and perusing tutorials I have read the manual! I think it just does not match my, er, learning style. Or I am not bringing to it sufficient number of coordinated brain cells. I've thrown myself at this with renewed determination and vigor every so often ever since I deviated. I think I get a bit further each time…

Some searching now with what I have managed to understand leads me to conclude that the functionality I have accomplished, albeit it a more roundabout fashion than magic_marty's example, will need two virtual channels no matter.

I'm not in danger of running out of virtual channels (yet, haha) but my conservative nature seeks a way to do it using minimal resources.

I have my min/max aileron and elevator idea working, I should give up and go fly it. But I think taking this thing as far as it can will be useful for cementing what I have managed to learn.

Again, thank you for your patient help.
