Paramotor help

Hello everyone!

I am trying to program my DEVO 8S Firmware 4.0.1 for my paramotor.

I need the same function as the video :

I can not can you help me ?

Thank you

PS : i am mode 2

Can you provide a pointer to an English Translation of the functions of the sticks? Or a text version of the description that I can point Google Translate at?

Je suis Français et j'ai fait un effort pour mettre directement en Anglais...mais cela n'a pas l'air clair

La fonction que je désire pour un pilote de paramoteur : j'ai fait un mixage delta qui fonctionne correctement pour un modèle avion. Hors pour un paramoteur, les deux bras du pilote doivent etre au plus haut au repos avec le stick au neutre. Ensuite quand on descend le stick, les deux bras se baissent et cela sur toute la course du servo. Stick a gauche le bras gauche descend, a droite le bras droit descend.
Lorsque l'on monte le stick, il ne se passe rien vu que toute la course du servo est vers le stick du bas.
J'espère me faire comprendre, en gros il faut déplacer le neutre complètement en bou de course haute pour mon cas.
Merci à toi

Hello Franck,

Répondre en français ne va pas arranger les choses

Answering in French is not gonna ease stuff

Here is a translation of what Franck tries to achieve:
"I would like to program my TX for my paramotor pilot: I did a delta mixing that works well for a plane. But for a paramotor, both pilot arms must at their highest position when the stick is in the neutral position.

Then when the stick is pushed down, both arms goes down by using the whole servo course length.

When the stick is pushed to the left, the left arm must go down, and when pushed to the right, the right arm must go down.

When the stick is pushed up, nothing should happend.

I hope I made myself clear, the main idea being to move the neutral position at the highest point in my case.
"

Thank you BitOne. I did say I'd try feeding French text to Google translate, but it wasn't very clear.

Let me try and translate that into a bit more detail with servo motions. Since you say you're in mode 2:

You have two servos connected to different channels. They are both at one end of the throw when the cyclic stick is in the neutral position.

The elevator stick should move both servos away from that end position when you pull lit down. The aileron stick should move the left servo when you pull it left, and the right servo when you pull it right.

It sounds like you want up elevator to do nothing. Is that actually correct?

Anyway, I read the outputs as:

100% to both servos at stick center.

-100% to both channels at full elevator down.

-100% to the left (right) at full aileron left (right).

-100 in the two bottom corners.

Any up elevator is the same as no elevator.

I'm unsure enough that this is right that I'd like to verify it before setting up a model.

I translated and it seems that is what I search.

"It sounds like you want up elevator to do nothing. Is that actually correct?" yes

I tried a lot of combinations without success

Ok, getting throws of 100 to -100 in a half stick it a PITA. Here's how you get them to have ~63% throw.

The channel tied to each servo will need to have a complex mix type, with two mixes. The first mix on both channels has a mux of replace, ELE for input, curve of <0, scale of 125 and offset of 63. The second mixer on one is identical, except the src is AIL and mux is min. The second mixer on the other channel has a mux of min, src of AIL, curve of >0, scale of -125 and offset of 63.

If you can't work around the values going from -62 to 63 but need -100 to 100, you need three virtual channels. They each start with one of the three different mixes above: one for ele down, one for ail left and one for ail right. All three then have two mixers with a Fixed curve with a Scale of 125 and a mux of mult. You might want three of those, as the first two only get you to 90 something percent.

I've attached them model.ini from my sim that puts those on the first two channels for you to look at.

I thank you enormously mwm, I would never have found it.

I brought some personal changes, and it works wonderfully .

I looked at your program and I did not understand everything ...

again thank you mwm

I found this post after having trouble with Aileron trim in a paramotor mix.
To recap:
Centre stick= both servos 100%
ELE down = both arms -100%
AIL = move just the R or L arm to -100%

The mix mentioned above is sadly a no-no (limited to 63% travel, due to the arbitrary limit of max =/- 125% scale in in DeviationTx).

I took a different approach, using 3-point curves:

[channel2]
max=100
scalar-=200
failsafe=0
min=-100
template=complex
[mixer]
src=ELE
dest=Ch2
curvetype=3point
points=-100,100,100
[mixer]
src=AIL
dest=Ch2
usetrim=0
muxtype=min
curvetype=3point
points=-100,100,100

[channel3]
reverse=1
max=100
scalar-=200
failsafe=0
min=-100
template=complex
[mixer]
src=ELE
dest=Ch3
curvetype=3point
points=-100,100,100
[mixer]
src=AIL
dest=Ch3
muxtype=min
curvetype=3point
points=100,100,-100

However, what's odd is that AIL trim doesn't work: Move the stick and the mix works, but adjust AIL trim and you get no change in one direction, and BOTH arms move down for trim in the other direction.

Is this a bug in DeviationTX? Surely trim should just replicate moving the stick a little bit from the centre position?
