Static data issues

Postby Deepfreeze » Sun Jun 30, 2013 8:27 pm

Hi,

i just bought the AQ FC and get this LOG with the static data. I tryed different things but it always looks the same.
Are these condensation glitches?

How can I get rid of it to get better results?

Log file for download:



(I cant post URLs because I am a new user, sorry)

I put the FC in a plastic box with some foam material. But I do not have any of this small bags to prevent condensation water. Would be nice if someone can give me a hint how to get propper data.

Thanks a lot.

*Sorry can a mod pls move this thread to the static data forum? I just saw it after I posted it.

This is the complete log file as a ZIP archive. I am not allowed to post urls so you only have to
write http and then the url I wrote in your browser. Thanks a lot for your answer.

Your acc looks fine a few minor glitches but the sim program should be able to handle those, however the rate graph has some glitches which maybe too large, someone else might need to chime in as to why thats happened. Your temp range maybe to low depending where you live, in Australia it's get upto 40+c often during summer so I ensured my graph got upto 60c. This can be done by reducing the size of the box and ensuring ambient temp is reasonable (22c in my case). I think the wiki suggest aiming for a temp +- 10c on the ambient you plan to fly in.

Thanks for your answer. I think flying at 30°C is the maximum I will reach here, but I will try to do it again with a smaller box and maybe without the foam to get better results. I am afraid of getting problems with the condensation water without the foam so maybe someone can give me a hint what to use to get better results.

You can add a tip of a stocking filled with rice to absorb the moisture. Let the foam in the box to insulate for heating.

Cheers

I did the calculation 3 times, but I always get the spikes in rate :(. Can I cut them out?

I would say that it looks like a bad gyro. Where did you buy the board?

Paul from flyduino, I bought the gimbal from you, but your shop messed up with my logins so bought the rest of the stuff from him. Can I send the board to you?
