Don't think that would affect a rescue climb though? Try increasing this to 9-10 degrees, make sure the servos are not binding at max/min pitch as you adjust it.
Noted

It does climb and climbs well.
Stabi -> Rescue collective pitch 47% (0% <-> -10%)
Not sure what happened here. I will check again this weekend then take it out for another flight.
Servo Travel Correction
Servo Travel Correction -> Pitch (CH1) -> Maximum 14 (-64 <-> 64)
Servo Travel Correction -> Elevator (CH2) -> Maximum 4 (-64 <-> 64)
Servo Travel Correction -> Aileron (CH3) -> Maximum 2 (-64 <-> 64)
Servo Travel Correction -> Pitch (CH1) -> Minimum -5 (64 <-> -64)
Servo Travel Correction -> Elevator (CH2) -> Minimum -30 (64 <-> -64)
Servo Travel Correction -> Aileron (CH3) -> Minimum -5 (64 <-> -64)
Can you get these to closer to zero by adjusting the link lengths with a swash leveller, are they required? That's quite a lot of correction.
Will check these again

If its climbing fast in a skids down rescue, then I think increasing cyclic ring will help.
I think this is used to control cyclic roll rate.
If its too low it will take longer to rotate 180° before climbing. If this takes 1 second then that fits with your symptoms. Set to 10°, check for binding and go test it.
Also check 6° setting is correct.

Just made some changes based on some of the above recommendations. Here's the revised .4ds file

And the rescue collective pitch is indeed @ 80% this time

So is this still an issue? Is it flipping over faster now?
What happens if you increase acro delay to 3 seconds?
