eLogger V3 fried and took all the accesories along with it!!

As tittle reads:

About a week or so ago I was flying my scale helicopter when we smelled burnt silicon fumes coming from somewhere inside it. Sure enough, I landed it and found out it was the EagleTree which was burnt to the core. Glad I landed it, because it would've not been nice to crash due to no power anywhere.

So, didn't thought much of it (since it is old and I wanted to replace it anyways due to the USB issue) A couple of days later I got a new eLogger V4 and I plugged the OSD Pro into the eLogger V4 to reconfigure everything and to my dismay it doesn't work: The eLogger not only killed itself, it took along the OSD Pro. So, okay fine, I go ahead and order another OSD Pro and get a request from Eagletree to RMA the OSD Pro. I haven't sent it yet because I was waiting for the new OSD Pro to show up to confirm is the OSD Pro what is damaged and not the new eLogger V4.

OSD Pro arrives Saturday and I get it working right away. Load the settings back onto it and when I go to hook it up to the fuselage where the other I2C sensors are, the OSD Pro freezes; I unplug it from the guardian/altimeter I2C plug and it works again.

Sure enough, I quickly removed the altimeter and the guardian from their location inside the fuselage and proceeded to test them with the eLogger V4 plugged directly to the USB... no dice. Neither one of these work!! The stupid eLogger V3 not only took down my OSD Pro, it also took the Guardian artificial horizon and the barometric altimeter V4.

The GPS V3 looks like it might've survived since it still works and reads what appears to be correct data.

I also have a couple of older eLogger V3s on my other helicopters and none these accesories work on the V3s either, the older V3 blinky LEDs stop blinking once I plug any of those components into the I2C bus. (same with the new V4)

So, let me get this straight: One component fails, all others burn out too? What gives? Is this on purpose? I mean, c'mon these components had hundreds of flights on them and were properly secured (bolted down inside a scale fuselage where I haven't messed with them for several years and magically they all burn out?

Now I have to shell even more cash to replace the whole Eagletree stuff?
65 for the eLogger V4
84 for the replacement OSD Pro
59 for a replacement Guardian Expander
43 for a replacement Altimeter Microsensor V4
251 dollars!!

SO BEWARE IF YOU ARE THINKING ABOUT BUYING EAGLETREE!, because it seems that if one burns, all the other ones will burn too!!, just to ensure you have to buy everything again.

And give me a break: 251 dollars, and no magnetic compass!!!??? WTH??

I can assure you that our devices are not designed to intentionally damage other devices in order for you to have to buy new ones. It is possible a catastrophic failure of a device can cause a short or power surge to the connected components but it would be a very rare occurrence.

Can you update your currently open support ticket with the additional info about the damaged sensors? We will get it sorted for you.

Regards, John
