Rescue blows right through any upper altitude limit set. Is that intentional? If so what’s the intended purpose?

The rescue is stopping at the upper limit once reached. The model should hold altitude at the configured limit.
This mean that upon reaching the limit the model stop to ascend.

That was not working for me. I tried it out I set high altitude limit at 9m low limit at 0. I triggered altitude hold and position hold and tried to fly above the limit, this worked it correctly stopped at the upper limit. I then disabled position hold and altitude hold flew down to about 5m then flicked rescue. It blew right through the upper limit and kept going. Once I disabled rescue it shot down to the altitude limit.

Triggering Rescue and Altitude Limit are two different things.
You have to always trigger the Altitude Limit.

I think you maybe misinterpreted what I said and I probably wasn't completely clear. Altitude limit was on during the entire flight.

I have 3 things setup.
Altitude limit is on its own switch
position hold and altitude hold is on another switch
Rescue is also on its own switch.

I tried 3 scenarios.
Altitude limit set other switches off. Try and fly above limit its stops.
Altitude limit set position hold/altitude hold set try and fly above it stops.
Altitude limit set, position hold/altitude hold off, rescue activated -> flies above altitude limit. Click off rescue it comes screaming back down to the altitude limit.

Yes, the behavior is completely correct from your description.

It does not matter what GeoLink feature is engaged. If you will engage Rescue on its own, it will always work as normal Rescue without any limit. Otherwise you would loose one possiblity to fully control the Rescue mode.
When Rescue is engaged automatically by Altitude Limit feature then it will stop at the limit.

Thanks for the confirmation.

Might I request you enable rescue to stop at the upper limit as an option in some future release?

One of the reason I switched from Demon to Spirit was because you can flip rescue and get so high up you can not see if you are right side up or upside down. So you can disengage rescue and come rocketing down depending on which way you put your sticks when you disengage.

I usually set my upper limits to where I can still see the heli orientation so if it stuck at the higher limit I could be prepared before flicking off. Maybe not an easy request to implement? Just throwing ideas out there.

If you have rescue assigned to a spring loaded switch, if it is starting to get too high just release the switch and it will stop.

I think you missed the point. If you can tell wether your inverted or upright releasing rescue just means your heli could come rocketing down towards the ground. You need to know which way your heli is oriented in order to know if your stick needs to be up or down when rescue is deactivated.

But if you use rescue Normal instead of rescue Acro, it will always rescue the heli to an upright attitude. I use rescue normal and after activating rescue I instinctively advance the collective to a positive pitch position before I release rescue. I know people are different and some prefer rescue Acro.
