Hello,

here is the special software for testing.

Please note there is new parameter in the Stabi tab - Altitude - Rotor Compensation.
It is recommended to set to 2 meters which is default value. This parameter is to make equal triggering while model is inverted. So the unit will engage rescue at the same altitude - in this way it can work with any model precisely without dependency on where the unit is mounted.

SOFTWARE:
https://spirit-system.com/dl/settings// ... -win32.exe

All other parameters are same.

When you will activate the feature, model should start to ascend immediately and stop after around one second. From this moment it will trigger at the altitude where the switch position was changed.

It is necessary to flash firmware version 3.3.3 that is available for pilots that send me serial number of their GT/GTR (via private message).

Hello,

firmware with the requested feature is prepared for testing. If there is anybody interested please let me know. We can offer it to anybody interested.
There are also other improvements regarding Automatic Rescue such as configurable pressure compensation for inverted flight or possibility to see Altitude even when model is not flying.



i am interested in testing this update.

Hi,

I have done my first tests with my GTs with version 3.3.3-spec and I love it. This is excactly the behavior I was hoping for - THANK YOU SO MUCH :D

Test systems and conditions:
1) Protos Mini strechtched to 360 size with Spirit GT mounted vertically on the side of the frame, behind the canopy, connectors facing to the rear.
RPMs ~3600, 3900, 4200

2) Henseleit TDSF with the Spirit GT mounted behind the roto mast with connectors facing forward.
RPMs ~ 1000, 1150, 1270
Very calm sunny weather - no wind at all.

Obersvations:
1) I have done about 40 rescues at different trigger altitudes set and re-set during flight, all worked reliably at the desired level.
2) In inverted flight it triggered about 2m higher so in my case I redued the "Altitude - Rotor Compensation" parameter to 1m. However 2m is a good starting point
3) After the upgrade the new parameter "Altitude - Rotor Compensation" still showed the value of the previous setting for the Hard Deck. Perhaps this should be reset to the default value of 2m.
4) In the HoTT integration via telemetry the new parameter "Altitude - Rotor Compensation" is still called "Hard Deck", which should be changed. Might be the same for other radio integrations.
5) Not directly related to the changes in 3.3.3-spec, but worth pointing out in the Spirit GT/GTR documentation is that in forward flight the trigger level starts to shift. In my case (both, on the Protos Mini and on the TDSF) it shifted downwards by about 2-3m. So people should not start setting the trigger level too low before they have understood the trigger level shift at varous speeds of their specific model. I forgot to test how this effect behaves in fast reverse and in inverted forward and in reverse flight conditions.

My conclusion for now:
For me the changes in 3.3.3-spec are a huge step forward in making the auto-rescue more useful and more reliable.
I will make more flights, especially in different wheather conditions, and report if I make further observations. As pointed out before, in a future version I would be good to still have the ability to manually rescue while in auto rescue mode but for now I'm quite happy with the first step.

Cheers,
Bernd

Hi, I'd be happy to test this as well.. I'm the guy who was having trouble with GT's Auto-rescue triggering too low in the support section.. Cheers

Hi Natesh,
you need to send a PM with the serial number of you Spirit GTs/GTRs to Tomas (user ZeXx86). He will then enable the firmware for it.

The required Spirit Settings 3.3.3 can be downloaded here - please read entire post.

hello Tomas
is that feature already in this firmware ?
because I cannot find the altitude in the settings program

thank you ;)
