Spirit rescued my heli into the ground

[velocity90]

I hope you reversed this in the transmitter so the diagnose screen shows it ok?

Now I came home finally and checked the whole setup through again and still nothing obvious found.
Greetings TPK

No, I never found out why it changed on its own. I was not going to fly it before the V2.0.0 update. I was waiting to see if the V2.0.0 update worked correctly, which turned out OK. I have two identical 450 helis with Spirits, and after the V2.0.0 update the TX programming and Spirit programming turned out identical for both helis. I guess it will remain a mystery, and could have something to do with a Jeti TX update, but this was the only EX-Bus channel that I noticed that changed and would be supprised if Jeti made any change to the EX-Bus data.

So you flew the 450 with the wrong collective showing in diagnose?

No, I noticed it had changed, but was not going to fly until after the V2.0.0 update. After the V2.0.0 update the Pitch direction was correct.

Please only talk about the crashed heli, this is confusing, also im pretty sure that spirit as well as jeti don't reverse collective after an update...

During update from 1.X to 2.0 there are major changes in the firmware so whole basic configuration can be different (including collective pitch).
But this thread is related with 1.3.2 (if I am not wrong), so it is a different problem.

ThePurpleKnight: What I want to find out is if the helicopter was not tilted to some side for longer side (even when you mounted the canopy). If so, then the problem could develop theoretically there.
But rescue is learning constantly so if it was not really for more than a few seconds, it is not a problem at all.
But at least for now, this is looking the most probable.

Alternatively what might happen is, that something take apart (push rod) and due to maintaining stability it then look like it changed direction. If all push rods were on the place (after the crash), then this is not the case.

Next possibility is, that BEC was unable to deliver enough power (high undervoltage happened) and everything was either resetted or frozen. This can be verified by a BEC tester - if this will pass, then this shouldn't be a case too.

So we have to exclude all possible explanations, then we can find the reason.

[ThePurpleKnight]

The canopy fitted nicely without to much tilting.
One DFC arm was still in position, the other one was the one with the blade hitting the ground. The pan was totally wrecked with all bearings so the arm can't have been loose before.
The BEC is the internal one of the HW Platinum V3 which can get up to 7A output current. Also when using the integrated BEC-test of the spirit the voltage only droped by 0.2V.

this doesnt make any sense , what if im learning to fly inverted the heli will stay for a long time upside down and still the system must be able to save the heli instead of crashing in to the ground.. ?

While flying or on the ground is not the same...

Rescue works fantastic.

Just don't let the heli lay sidewise for long after initialization, and then put it on the skids, take off and immediately try Rescue.
