The Trouble is : if you use flightmodes sayTakeoff/ Flight/ Landing.
and you would use crow and a elevator offset and for crow ailerons up.
say in flight you use 5% down elevator , and in landing 40% down elevator with full flaps and raised ailerons.
you can not use the assist.
the assist sees this as a Stick input.
maybe someone has a different experience?

I'm going to have to experiment with this myself as I'm hearing conflicting info. While I'm sure 40% Elevator trim may well cause problems as that is a large value, none of my jets require more than say 10% down elevator with full flaps. One of my friends has such a setup with similar values to what I expect and he says he has no problems when changing flight modes (cruise to full flaps, etc). It may also have to do with heading vs Normal / Damping mode and in fact the Assist manual says that changes in trim aren't allowed heading mode but are not a problem in Normal / Damping mode which is all I'll be using. Wouldn't be the first time a manual is incorrect though so I'll have to test it out properly to see if my setup will work or not..
example ultra flash
needs in flight with the correct CG about 1mm down elevator , in landing however with crow (full flaps ailerons about 5mm up elevator needs about 19mm down) to fly neutral and land.
this is a situation the assist can NOT cope with as far i can see.
making the Assist not suitable for it , therefor all my jets need these offsets.
whatever you change in the offsets in flightmodes the Assist sees this as a Stick input.
Just saying if a Demon can do this perfectly , why shouldnt a assist cant do this?
Didier mentioned to have the assist learn these offsets also so that the assist could learn the unputs in flightmodes.
this is however almost impossible , if the sticks would have encoders it would be easy , but they have hall sensors.
with the Demon its pretty easy you do a flight , trim the plane in flight mode . land Relearn the stick and trim positions and you are done.
no matter in wich flightmode i am in , it stabilises the whole time.
for now the assist is not really suitable for Jets is my opinion at this moment.
i am sure the guys at Jeti will come up with something .
there should be a Jet setting or something that would be always stabilizing no matter the stick inputs

Get rid of Heading hold and Horizon. Assign Normal/Dampening to only 1 of these positions.
My setup is:
Position 1, No Gyro.
Position 2, Gyro Active - Normal/Dampening.
Position 3, No Gyro
F16 CB200 Rsat and 10ch Assist is performing perfectly. I' not interested in Heading or Horizon Mode in a Jet.

Digitech - my Demon sees trim like the Assist does and the Demon reduces the gain due to stick priority. It's the same for iGyro, ACT Fuzzy Pro, Eagle Tree Guardian, Aura 8 etc etc. Any gyro sees trim as an input because no gyro can tell the difference between a stick or a trim causing the data signal to change. If your Demon and your Assist behave differently it is because you have given them different stick priorities. So in that respect there is no problem using Assist in jet models. Assist treats trims like every other gyro. The Aura 8 overcomes the problem by using a separate channel to signal trim changes which the Aura then activates, otherwise even the Aura reads transmitter trims just like the Assist does.

me neather , however i want stabilization in all 3 modes ... this is the way it should work.
i dont use heading lock eather

Of course everyone has there own way to set-up an airplane.
What is confusing is that Jeti talks about 3 flight modes for the assist.
We use the word "flight mode" or "condition mode" as an airplane set-up in the TX.
Maybe it is better we call the flight mode's for the assist RX "assist mode" and flight modes for the TX "flight modes".
What I want to use is the following:
I use 3 flight modes with digital trims on "separate".
-take-off FLIGHT MODE: different dual rates, expo's, flap 10 degree's, elevator compensation
-cruise FLIGHT MODE: different dual rates, expo's, flaps up
-landing FLIGHT MODE: different dual rates, expo's, flaps 45 degrees's, elevator compensation, CROW
I have coupled the 3 flight modes to 3 assist modes with the same 3 position switch.
-Take-off flight mode coupled to Assist mode 1 (damping)
-Cruise flight mode coupled to Assist mode 2 (also damping)
-Landing flight mode coupled to Assist mode 3 (also damping)
I have set-up a 2 way switch to switch on/off the gyro.
The problem is that you ONLY can calibrate the sticks in ONE ASSIST MODE.
So if I calibrate the sticks in landing mode, everything works as it should be, but will affect the other assist modes.
If I calibrate the sticks in other modes, the other modes works correctly as well but again will affect the landing mode.
I'm in the middle of a conversation with Jeti and they acknowledge my problem. This is what they reported back:
Stabilization always calculates the input setting if you change this input mix, so it will always have the effect of suppressing the lever (exactly as you described below). These mixes can be used only if the stabilizer is off.
So you have two options:
1. In the mix, remove the elevator.
2. In the receiver, disable stabilization of the elevator for this mix.
I have suggested Jeti to change SW so you can calibrate sticks in every "assist modes".
To be continued.

Hold on! My Assist works properly with crow braking!! I have aileron 1 and aileron 2. Stick priority is 125% because I like gyro gain to zero as soon as possible when I move the sticks. Confirmed that if I move aileron stick to about 3/4 travel the gyro has no effect. Butterfly menu set to 100% so that it drives both ailerons well beyond the aileron stick priority limit. But operating the crow stick has no effect on the gyro, it is still stabilising both servos!!!!!! Assist is clever enough to know from the directions of the servo signals to 2 ailerons whether they are being operated as ailerons or being operated as crow/elevons etc.
My Assist stabilises aileron with full crow applied. Therefore if yours does not it is not a fault in the Assist....

understood , but do you have down elevator when you set your crow??
the zero point moves if we set gyro on or off..

I do experience the problem of neutral shifting when Assist is switched on or off if the trim is not centred.

My Jet is not flyable with crow and NO elevator compensation.
Hopefully Jeti will sort this out with SW change
#167
Hi all I am setting up a assist the same and having the same problems does anyone know if jeti has sorted it and can you just set a two way switch so it’s gyr on or off it’s a bit scary putting a 6k in the air and not knowing if it’s going to be ok

I also use a voice command to alert “gyro on/ gyro off”.
Bench testing is highly recommended prior to flight. Ensure none of the control surfaces move when switching between modes. Check that the control surfaces apply correct input by moving aircraft in pitch, yaw and roll. Do this several times just to make sure.
On a new model, I always take off with gyro off and only activate a few mistakes high. So far the default settings have always given good results.

Hi thanx for all your info has any one done flight modes so eg flaps take off elevator 2mm down and second flight mode flaps landing and elevator 5mm down as when I do this the elevator goes to full travel down if I switch to head hold you think jeti would have sorted it more or less like the cortex as they work fine in all trim changes

Still so so much to learn here with flight controllers for me. But much easier than the many years I spent tweaking heli flybarless controllers.

I tried setting up this with cb200+rex6assist and mspeed sensor connected to cb200. But I was not able to use airspeed compensation as its missing in menu. 1.07 software used. Anyone has ideas or newer 1.08 software to send as 1.09 has airspeed compensation removed due copyright issues.
And to clarify:
Should I run it like CB200-REX6A-RSAT at rx1 port and leave RX2 port empty or , CB200-REX6A on rx1 and Rsat2 at rx2?

Well I found another thing the Assist won't do and that is stabilize UDI output. Since they have a separate"Stabilze EX Bus" control for the Central Box I'm not surprised but I had hoped it would. Hopefully at some point Jeti will update the firmware to stabilize either UDI or EX Bus output so that it can be used for power expanders like Power Boxes or my XPS24 instead of just the Central Box.
