2nd RC, 1st OpenTX

openTx has introduced a range of new features, ideas and bling. It is fast becoming the firmware of choice for many users. openTx will run on ALL current hardware platforms, including the gruvin9x and sky9x boards. Work has already started to support the new FrSky X9D radio!

As a second subject.
I don't see how pitch control will work unless you reverse the elevator directions on the front and rear elevators.
It looks like you will just increase or decrease lift if all elevator surfaces are the same.
The plane may go up or down, but it would not pitch, so more thrust would just man more elevator like climb or less.

But I have no feeling for plane in this configuration.
Am I wrong?

Yes, I've got it so when I push the stick forward the front CSs come up and the rear go down...an vice versa. All 4 have both pitch and roll....all 4 will have 2 flap modes also.

I'll certainly look at 50 vs. 100%. My first objective is to get all the functions working and then tune everything. I did notice an odd movement when moving the stick around the clock as far as it'd go. Probably what you're referring to. I didn't pay much attention to it.....I want all functions operating before getting into the final adjusting. I think I'll understand more of it when I get that far. ...probably will need to adjust the linkage a little too.

I'm finishing the Monokote tomorrow.

I appreciate your help, but please understand. I don't understand 2/3s of what your talking about. I've never done any of this before. I have never even flown an RC.

I did some extensive free-flight building in the '90s. That's it. So generally, I don't have much, if any knowledge about this.

....and now that I've added all of these mixes ive found there's no way to adjust the servo center as you can in the outputs. The "ppm center".

Added:
I was looking just now. I can copy and input.

You can only have one servo ppm center. So outputs takes all the active mixes, evaluates them to one value and sends it to outputs.
I don't see what problem you want to solve.
Note you can put an individual Global Variable (GV) on each mix OFFSET.

Added: ??...What does copy and input mean"
You only have one OUTPUT per channel.If you copy the output to a different channel, it will imply another servo used on that channel

In the mixes I may have found an important error...my miss. When adjusting an "offset" in the mixes, some read 1,2, 3,4 or in the minus side. In other mixes instead the offset picks G1, G2, G3....they're different.

in FM1 (flight mode 1), all 4 wing control surfaces need to drop about 15%. In FM3 they need to drop about 25%. Two flap modes that still have pitch and roll.

Oh well, thanks for the help. I'm gonna have to start all over to find out why I have 3 of the 4 wing servos inverted. When I started the programming I was still painting the fuse and skinning the wings. I'm surprised all the pitch and roll on all 4 work. I may leave notes here, but don't expect answers.

Thanks.

When I try to set the weight within mixes, some times there's a number to set. 100 to -100. Sometimes it gives me G1-G9 I think, or to the negative -G9. Then you can't put it on 0. Your stuck with the G number. I have not found this in any searches I've tried. ...can't get past it, and it doesn't seem to make any chance that I can tell.

The G means you have selected a global variable to be used for the weight.
Try holding the ENTER button in for a long time, this may toggle between a number and a G value (I don't use openTx so I'm guessing this is how to swap them).

I'm not sure I understand, but it seems like you are somehow getting checkboxes checked that you do not want..
You have to look at the checkboxes carefully.
If you are doing this on the tx it is harder to not move the scroll wheel when you try to set things.
Yet another reason I do 95% of my setup on Companion.

I did some experimenting (in the simulator that is part of Companion, ..hopefully working the same wayit does on the Tx [it generally does])
If you highlight the Gv in edit a mix. a short press allows you to change the GV.
...A long press of ENTER (the scrollwheel) it switches from GV to Weight.
So if at sometime you pressed too long it effectively switched weight to global variable...a virtual checkbox I guess.

It would be perfectly logical for a longer "enter" would do that. Thanks.

I plugged it into companion and when the voltage got to 8.1v the radio started beeping...8.2v, it started beeping a lot and it seemed like the battery voltage was going up and down. I unplugged it, not knowing what the alarm means. The batteries say 3.7v, but they might be junk. They were definitely heating up.

Yes, holding the roller down switches the weight to numbers. The Gs 1,2,3,etc are global values you set in that menu?

No. A problem with names.

Each model has up to 81 Global Variables visible in flight modes. (9 per flight mode and 9 flight modes.)
GVs are numeric values.

The radio has Global Functions that can be used in every model. These are set in the Radio Settings on the Global Functions page.
GFs do something...Play Track, start LOGS, control Volume, perform Instant Trim, Reset...

In the "mixes" menu, the "offset" setting does nothing. Am I missing something?

I have this on 4 servos....I miss a detail here and there. I also am have other things to deal with so sitting down next to my model and spending real time has been fleeting lately, and my batteries are junk. I'm making progress, tho slowly. This all works but refining it may take quite a while.

SBup will have 10% flap for take-off, SBdn has 25% flap for landing, tho I may vary the percents. I may only go 20% for landing, for instance.
FM1 is SBup, FM2 is SB-- and FM3 is SBdn. I just happened to work on a mix that I missed the switch assignment.
Total 24 mixes on 4 servo channels? A lot for a novice. I still may need to vary the weights and offsets.

Yeah I missed a switch setting, but I think I need to pull a servo and rotate its arm 1 click.

Now you can see why I don't watch video. I use my data uploading my own. This shows I'm getting there. I found this link you provided most helpful:

I learned something. Each weight setting is independent. Every servo and connected linkage is completely different....if you want them to work the same. One aileron on one channel may be 40 and another aileron might be 6, in order to make them travel the same.

You would adjust servo/linkage-specific things on the outputs page so as to separate this aspect from the mixes, you want those the same.

This is in flight mode 3 where all CSs are 25° down. I want the travel restricted...in landing mode. I've got one rear elevator weight at 20, the other at 10. They're doing exactly what I want them to do...and their movement is identical to each other.

In flight mode they were already balanced.
In landing mode I want them to stay close to 25% down and not have lots of movement. It's true, I could possibly keep adjusting the linkage (over and over), but using the software seems to get the job done.

I do have a bit more movement in the forward elevators. They are closer to the CG.

I also need to restrict all 4 ailerons in FM3. ... haven't gotten'round to it yet, only a little. Just fine tuning.

Ignore Kilrah at your own risk!
His answers are many times terse, but it is sage advice.
He knows OpenTX and where things belong.

No I haven't a clue why you will not look at videos.

Ideally:
- How the response to a control input should be in inputs
- How channels should ideally relate to each other in Mixes
- Adjustments to take account of mechanical differences in outputs

That way things are separated by intent and most things you'd need to tweak are restricted to only one of the 3 with as little crossing as possible.

.
If you adjust a servo in inputs or outputs (I did when centering the servo) then it effects ALL.

Why would you adjust a global input or output if you are only trying to adjust one flap mode in FM3?

In neutral flight mode it was easy to get everything centered. I did that near the beginning....or at least it didn't take long to figure out how to.

In all 4 wing control surfaces have got aileron, elevator and 2 flap modes. Making a global change in inputs or outputs would effect how all the flight modes operate. Why would I want to do that? Am I missing something? 4 functions on each wing control surface, controlled by FM1, FM2, FM3, etc.

I'm only adjusting flight modes now.

Ok, if you say so, but I've written it down in a number of the posts in this thread. I'm sure the fact that it my first time bores everybody, so they don't actually read my drivel, but I've mentioned it several times.

4 wing control surfaces with aileron, elevator and 2 flap mode, which i"ve also posted in this thread. It's ok, ya'll aren't required to respond or read my posts, but you've been helpful thanks. I also posted that I didn't expect responses, but might post more for notes. Bet you didn't read that either.

Look just 5 and 6 posts up. Flight modes.
