Hello

I have a problem with my spirit 2 system.

A few flights ago, i crashed my heli - when I was hovering, the helicopter crashed into the ground with full negative pitch. I dont know why my heli do this.

I rebuild it, and today i did 4 flights.
2 times i have a strange situations - when i do a tictoc, my heli „rolled over on his back”
And it took him about 2 seconds to get it on normal position. I have the impression that he did not respons to my commands In this 2 seconds.

In the last time I crashed the helicopter, and today, when I had problems with it, I wanted to read the logs and I got this Message.

Is there something wrong with my spirit?
To this day, I don't know what caused the last fall, or what caused today's problems but i didn’t read it...

Hello,

we are sorry for the troubles.
I highly do not recommend to fly until the problem will be found.

To be able to help you we will need to know everything about your model.

It could be caused because failsafe was triggered for some reason. So you can try what will happen, when you will turn off radio.

When collective pitch will go?

When unit is turned off, it is moment when it is saving log to the memory. When for example something caused a short or voltage was discharged very quickly, the unit will not be able to save the log completely. So then the message will happen.

You can retest it just by turning off your radio. When you will repower the unit then after next Log opening it should display the log with receiver signal loss.

maybe do a bec test to check if bec is able to power all heli without issues

My model is XLpower 550

With XL engine 4025
HW V4 120a
Gdw DS590MG x3 on swashplate
Gdw DS895MG on tail
And 2x spectrum dsmx satelite

My failsafe is engine of and pitch -12, i tested it when i crashed a heli, but i cant read a log...

~3 weekend ago, I read the logs without any problems, it was signal lost, it disappeared after replacing the satellite cables. there were no problems at the time other than these errors

Now i cant read log from previous flight, i must test to read the log when i turn off the radio.

I have already tested a bec, in spirit setup, all is well with him.

This model have ~600-700 flight in this setup. First -500 on Ar7200bx, ~70 on k-bar, and now 40-50 on Spirit 2.

I dont have any problems with my heli on previous systems. All the problems started after installing the spirit 2.

When i mount the spirit 2 I couldn't set my tail, it was not possible to fly the model with the default settings. I finally made it, a few flights later he started jerking his tail.
I replaced the tail servo with a new one, the problem is gone. but my servo tested in another same model works fine.

In 2 flight on new serwo, When tail worek fine my heli is crashed - the situation that I described in the my first post...

I don't know what to do, I don't want to break the model again.

Now, When i testing the failsafe - cut Off the transmiter, i can normally read the log after restart heli, i have a error with signal lost, and low voltage when I disconnect the battery - the log is normally saved in home, but not When i have a problem on flying field and want to read this logs after back to home..

maybe -12° as failsafe is a bit too aggressive

If you will be able to remove the unit without a scratches from your model we can send you replacement unit tomorrow just in case.
Then you can be absolutely sure there is nothing wrong with the unit and we will see the outcome..

We will need only your address. I am not sure what do you mean by default settings. If you will proceed through the setup wizard then it should all work at least well for basic flying. No abnormal settings should be used, if yes, then this could indicate some problem.

Unfortunately I am unaware of any case within 10 years like this so it is hard to help more. I only recommend to carefully check if no cable is damaged and maybe to spoolup the motor without blades to see if there is any strange servo behavior.

Are you using for example ESC telemetry?

-12° for failsafe, and still don't know what can be the problem...???
Use 0° for failsafe!!!
So, if your heli had lost the signal, the huge negative pitch pushed it to the ground.
But it's only an assupmtion, there can be more problems. For example: why can it lose the signal? what can couse it?

I think I can get it out without damaging it

In default settings - When i mount the spirit in my heli and I set the wizard after first starting it, the tail in my heli cant hold on soft flight - „he did what he liked”.
I set up it, and within ~20 flights Everything work fine.

The -12 in failsafe in my opiniom is a safe setting for the user, but not necessarily for the model...

failsafe could be the reason for my model crash, but then spirit should show me in the logs that it lost the signal, and it did not do that either after crashing the model or after yesterday's flight problems. Yesterday definitely failsafe did not work - this was not the behavior of the model in failsafe..

I don't know what was wrong when I crashed the model, but now I'm afraid to fly it, and the spirit itself in this situation makes any diagnosis difficult for me ...

Edit
I didn’t use any telemetry in this model. I use a governor from the esc, and the yellow cable is loose in model.

sorry... but i think this is a wrong assumption... if you loose Rx link in a simple curve away from you the -12 will accelerate the heli towards you with the remaining inertia in the rotor (and a 550 has already enough energy stored in the rotor). even more in many other situations. more inverted, knife edge or whatever could be the position of the heli even you did not fly like this, but the heli did DUE TO the loss of signal - could by any. you have a 50:50 chance...

there is no real safe setting for a heli, but in my opinion -- +/- 0° will stop acceleration in most situations... and let the heli simply fall down (hopefully ballistic).
