Spirit System

I have set up the spirit on my logo 480 and man does it fly nice! Perfect piros and completely locked in. The tail is perfect!

The only issue I am having is with rescue.

At the beginning of the flight, reacue works well but a slight angle. At the end of the flight, rescue is almost verticle and scary at best. It has not reversed pitch, but, I al afraid it has the possibility to.

Everything is setup properly so I have boiled it down to 1 of 2 problems.

1. The unit is not perfectly aligned with each axis. This is most certainly possible as I eyeballed the position and the logos FBLS tray is huge!

2. The logo has about a 2.5 degree forward slant when on its skids. Could this lean during initialization be causing the issue?

Thank you!

I used a micrometer to measure. The spirit is about 1.5mm to the left of the tray (off center).

Is that an issue?

I'm pretty sure it's not a vibration issue. The logo is smooth as anything.

Hi

If you can, please try to enable extended signal processing.
If it does not help, is possible that you can try one unit from other helicopter, please?

Ok, I will test it today.

Only did 1 test flight so far as it started raining as soon as I landed.

With extended signal processing enabled, the rescue started with a slight tilt, however, it never changed. Rescue always had the same slight tilt even after many tic tocs and piro flips and hard 3D.

I also changed thr tail blade grips from a CNC set back to the stock plastic ones, this may have reduced vibrations as well.

I may try again without extended signal processing to see if that helped.

Should I still try a different unit?

I will fly 6 more packs ones the rain clears to fully test today.

Thanks for your info!

You can still try to change the unit if it is not a problem, just to be sure there is no difference.

Ok, did 7 flights. Rescue on some flights was worse than others. Sometimes it would be a 45 degree angle.

None of it was as bad as yesterday without it.

I'll try switching the units out. It's a pain in the butt to do, but, will be good to see.

What are possible causes of this? Could it be the angle it initializes at or vibrations?

Well, if you can observe such drift, something must be very wrong. I mean vibrations must be extremely high or inclination during initialization is too high.
If you are sure piro optimization is OK and mentioned two things too, then it could be something with the unit.
There are unfortunately some things that we can't check nor fix during the manufacturing process and can possibly affect bailout precision even when normal flight is without any issue.

Normally helicopter should be in horizontal position without any deviation when the bailout is activated.

I used the white mounting tape thah came with the Spirit on the logo. All my other helis have the Grey 3m tape. Should I use the 3m of the foam tape that came provided?

Ah, ok. I'll trade out units and see how it goes.
