I understand what you mean, but the problem is that when I activate this function at around 35 meters altitude,
the Heli goes direction to the ground, and even if I put maximum pitch on the transmiter stick.
Channel are properly setup, because I see on the Diagnostic windows when I switch the function= Activated"
Can we have a Teamviewer today?

Please activate Rescue mode at the bench. Then observe where the swashplate is moving. This is very important. It is not needed to test in flight.
Then you should always see that collective pitch is positive. Can you confirm it is working in this way?
If you can see a negative collective pitch then it mean that some other basic settings are not good. And we have to find what it is.
It is very important that you can also see that collective pitch channel is moving in correct direction. When you move it up, you see progress bar moving up to 100%.
When Rescue is enabled, collective is driven by the unit, not by pilot (with default settings).

Hi , I not see a lot of positive pitch when I activate the function and I think there is the problem, I test the function "Rescue Automatic by undergoing the pregrogrammed minimum altitude= Autorescue)
in the two possible way, one time only with the GT presure sensor ( GeoLink Tab Switch off) ,
and the other time with the GeoLink enable plus the Function Altitude.
And the two different test are the same result, when I activate the function at around 35 meters altitude, the Heli goes direction to the ground, with no reaction of the pitch even full positive inputs from the transmitter.
Also on the transmitter Servo Test window , I see the channel properly works.
If you can a TeamViewer today?
I send you two weeks ago the backup ds, you not can see there?
(Also I test the Position Hold and works very fine.)

Hello,
I think it is required to verify the basic settings.
Please click at Servos/Subtrim (tuning) menu.
1) Then all servo arms should move to the center as close as possible. So they are perpendicular to servo cases.
2) At the same time swashplate must be levelled perfectly.
3) And at the same time there must be zero pitch between main blades.
Can you confirm all 3 points are correct? This is required to get a proper flight performance and also to Rescue mode to work correctly.
When Rescue mode is active, it does not matter where your collective pitch is. It should not react to this normally. Otherwise it can't save/control your helicopter.

Hi, now I make a Strange observation, if I select the function with the channel selection window open, the swahplate works, if I go out of the channel selection window, the swahsplate doesn't work???
So I make the follow Test, if I disconnect the USB connector while I'm in the channel selection window, the swahplate still moves with the stick inputs as it must, but when I disconnect and connect again the Heli, the problem again, no control over the swashplate ( not moves) with the Transmiter Pitch stick ???

I like to remember, I was Test Pilot 8 years ago with Skookum with GPS Functions, and never crash a Heli
even when testing Beta Functions. I do this hobby now for more than 40 years.
At my Goblin 500 ( Test Rabbit) has more than 150 Hours Flying Time, and there is still the same Factory first Main Rotor Blades.

The unit is in mode where Rescue is disengaged. But when you have "no swashplate control" it is engaged.
When Rescue is engaged, there should be NO swashplate control.
Only slight swashplate deflection is possible - depending on Stabi/Stick Priority value. If it is 0, then there you can't make any corrections. But it is not too important.
Unit can be in a various modes when Spirit Settings is opened. For example when configuring Limits or when setting up Subtrim, there can be no control completely.
But when you are flying or software was not started, it must be always identical.

Hi thanks for the quick replay I apreciated, so I make a double test on the bench and reduce the Minimum altitude to 1 Meter and see there the swashplate goes down itself.
Also I not expect that the measure of the sensor has so much variation (10 meters) since I setup the Heli on the first floor.
I setup now the follow the "Function altitude Limit Rescue" with the GeoLink ( direct channel assign) and
( Switch it off in the Bank)
and on another switch channel the function "Position Hold plus Hold Height" on the software , on the Bench looks works all, I will Test flight this afternoon.
For the problem with the functions on the GT direct also without GeoLink, I start to suspect the origen of the
Problem, but for this I have to reset the GT again to Factory default settings, will confirm.

Hello,
Rescue (Automatic) can be fully tested at any altitude. It is completely irelevant where you will try it to activate. It must work at any altitude, because unless the model is flying, it will act as when model is at 0 meter altitude. So it does not matter what Hard Deck limit you will set. It can be 1 or 50 and result will be same on the ground at any moment.
It also does not matter what Rescue is configured. Outcome must be same with any type on the ground, when model is skids down. Swashplate must go always to defined Rescue Collective Pitch value. Default is 60%. So 60% of your full collective pitch range. But I dont know what is your settings now.
If you can see rescue is going down, then it is 100% certain that the basic settings is not correct.
It is recommended to proceed exactly according Setup Wizard. Especially when there is Subtrim step.
Both Altitude Limit from GeoLink or Rescue (Automatic) will work when configured correctly. I can help you with each step, but first we have to make sure your basic settings is correct. It can be easily verified by enabling Servos/Subtrim (tuning) menu. All servos must go to neutral position - 0 angle - perpendiclar arm position. Swashplate must be exactly levelled and there must be 0° between main blades. Any other condition will result in a bad flight performance and incorrect Rescue behavior.
