Hallo,
I fly an Trex450 pro equipped with Spirit2, Stabi mode on, coaxial, no geolink.

I take off and hover at 1 /2 meter high, hell is well responding to the command, stable, no vibration.

After 2/3 minutes it suddenly drift to the left not responding to the stick right command and obviously I have to land immediately.

I can I solve this problem?

Thanks

Hello,

please see this page:

Especially section 2 and 3. I believe this can help you.

Dear Sir, thank you for your patience,

I have set extended signal processing and stability correction as you suggest.

The problem is still present.
It looks like: when the heli drifts to the left, even if I move the aileron stick to the right, the swashplate doesn't tilt enough to correct the flight, as the swashplate range was suddenly reduced, not enough to recover the drifting.

The swashplate follows the command in the first minutes of flight but not from the moment it start drifting anymore.

Mechanical settings are ok, the swashplate is perfectly horizontal after the power up.

Thank you for helping!

I've had the exact same issue on my Goblin, Spirit support has been excellent, hopefully we can sort this issue out.

Thank you for the message.

Did you set Extended Signal Processing ON and Stabi Correction OFF? Is this correct?

I have set stabi correction and Extended Signal Processing both on, as suggested suggested in the Imprecise rescue manual page point #2.

I also have reset the Spirit II to the factory setting and start a new configuration through the wizard setup, but the drifting is still present.

Anyway the heli is not affected by strong vibration

We look forward to receiving some help.

Thank you

Which TX are you using? I have a Futaba T10J.

Oh, please turn the Stabi Correction OFF.
In the guide there is one or another option. Not both ON.

The problem seems to be at lest partially solved setting Extended Signal Processing ON and Stabi Correction OFF, even if today is windy so I cannot check if the heli is stable.

Surely it doesn't drift as before. On other hand I realize it doesn't keep the "Position hold" via Geolink.

I will double check it in the next days without wind.

Thank you for your help.

Good morning, no wind today.
The heli is stable, just few correction to keep it fixed.

Configuration is: stabi function coaxial, geo link module activated, position hold in geolink - aid module checked, activated by tx switch by channel 8.
Blue led on geolink.

When the position hold is activated by the switch the heli flights away.
Compass correctly set.

How can fix this new issue?
