Throttle Curve is Chopping End Points )--:

[bobnj]

I'm using extended limits, but I set them back to 100 with no difference in the result.

LIMITS at 125 in Limit tab of Companion
My MIXER percentages are at 100 in Mixes tab
STICKS are at 100 in sticks tab
CURVES won't go any higher than 100 in the Curves tab or radio


The 17 point linear curve works fine in the normal mode.
Any other curve works on a switch, but the throttle servo doesn't move from idle until the stick has moved up 9 clicks.
It also stops working 9 clicks from the top.

To me it seems like the curve is looking at 100 and not 125 or something.
Like I said, I did try it without the extended limits and got the same result.

Again, the first curve in line works ok

Something simple I'm missing I hope

Any thoughts

Thanks
Bob

100% throws on OpenTX is already about 125% on other common radios. You REALLY need a good reason to go past this and use extended limits, in a usual setup you would actually want to reduce them.

My guess is that the throw is already so big that your servo does not consider the signal valid anymore and stops responding. You'll want to adjust your linakges so that smaller radio throws are needed. And please read the model setup guidelines in the manual.

Maybe post your EEPROM at some point too, your setup seems kind of strangely complicated

This is a bench set up on a servo board.

The servos reacted the same way with the extended limits not checked.
After what you say, I'll put them back to 100 and wonder why they are an option at all then.

The servo recognizes the validity of the 125% in mix #1 default.
It won't recognize any other curve but the first one for some reason?

Do I have it wrong to set up the curve in the MIXES screen?

[bobnj]

When the throttle limit is reduced to 100, there is a definite 13 to 15 degree reduction in servo movement/throw.

Does this mean some resolution is lost too?

Also, when I reduced the limits in Companion, it shows 100 on the limits screen, but still 125
in the SERVOS screen on the transmitter.

Companion does not have a servo screen and now I am not sure how the LIMITS screen in Companion, and the SERVOS screen in the transmitter feel about each other?

On CH1 the first line is always active.
The other lines, when activated by the switch, are ADDED to it. So you have 2*100% of the throttle stick added together. Whenever the sum of curve 2 and either of curve 3 or 4 that is activated exceeds 100, it clips. I suppose you would want to either assign SCup as switch in the first line, or set the type of the other 2 lines to Replace instead of Add.

You could probably get rid of 2 lines in the ailerons by using the Differential setting in the mixer.
I don't see why you're using 2 separate lines for your compensations. 2 lines with -10% Rud Curve (x<0) and -10% Rud Curve (x>0) is the same as a single -10% Rud line without a curve.

Whew!

So what is "SCup" and how do I learn about it/use it?

I set up the aileron differential per a video by Scott?
Can you school me on the "Differential" setting in the mixer?

I needed a Knife Edge mixer and didn't know any other way to get the ailerons adjusted in a Knife Edge mix
where I would need to either get more or less bank in the mix.
My mix although rudimentary would need two edits at the field to either get more right or left aileron bank
since I would need to add more up or down to each one.

So many questions...

SC↑...

SCup means Switch C in the up position.
EDIT: Too slow!

[bobnj]

I did as you suggested and it works as advertised.
Thank You all.

There will be a time when maybe I can reduce the tremendous load on everyone here that helps out, and actually
be able to help out myself.

It's great work that you do, often with no appreciation or thanks.
Keep it up!
