In normal rescue mode, when I hit rescue when the heli is inverted, it does not climb out but merely hovers at the same altitude before recovering. I find this to be rather nerve wrecking when I initiate recovery close to the ground as it seems about to slam into the ground when it flips / loops upright. Therefore, a good climbout before recovery will be safer.

How do I set inverted climb out to a higher altitude before it recovers right side up?

Hello,

the problem might be very likely in the swashplate settings.

It is important that when you enter Servovs/Subtrim (tunjing) menu all servos will be at the center and at the same time swashplate is leveled and at the same time there is 0° between main blades. Could you verify this is true?

Check your Acro Delay setting in the Stabi menu. By increasing this setting the model will climb longer before the flip to upright.

Yes, in order so that heli will ascend first set Acro Delay. This will ensure helicopter will climb and then flip and then climb again.

Just double checked. All servos already centered, swash levelled, blades @ 0°

My rescue settings are here:

Yes I have. I set it to 1 sec. When I hit rescue, it merely hovers inverted for 1 sec before flipping upright.

Verify its 1s and not .1s also what is your Rescue Collective setting ?

Can you attach a pitch gauge (blades out to the side, not in line with the boom), check that collective pitch is zero at mid stick,

Check +- pitch is equal at max / min stick. What is max / min pitch at max/min stick?

Check pitch is zero at mid stick in the diagnostic tab.

Check servo travel is zero at max/min stick in servo->servo travel correction->setup.

Check Limits(tab)->collective pitch is a sensible value (e.g. 160 - 180)

Then set the mid stick and the pitch gauge will be zero.

Hit rescue - What is the collective pitch on the pitch gauge with rescue enabled?


Upload your 4ds setting file as an attachment to your post on this forum.

Yes. Collective pitch is zero at mid stick with blades out to the sides.


Yes, both max and min equal +12° - 12°


Yes. Pitch is zero.


Yes. Servo travel is at zero.


about 100-120


Done.


About 10.5°

Cyclic ring looks low at 5 degrees, what heli is it?
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.

Also, in a skids down hover, hit rescue. Does it climb?

You've measured 10.5 degrees of positive pitch in rescue, so it should be very capable of climbing, unless your motor slows down/boggs out significantly etc at the same time?



I'm hoping that's a bug in the 4ds viewer, maybe someone from spirit can comment on that....
You measured +10.5 in rescue out of +12 so that's about 88%, as you stated it was 80% so I think the 4ds viewer is wrong.


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.
