By the way I attatched CLI data from the ADC, the Gyro/Accelerometer and the IMU. Also, when I say I'm a noob in the video, I mean in a programming aspect. If it is a software problem I will *never* find it on my own....

How is the board powered?
And what voltage is going to the board?
Which board do you have 1.0 or 1.4 APM?
Which code are you using?

Regards

In your video you didnt get mtk lockup... it needs to go solid, then youll get C (red) lit.

Do you ever get this far?

What version of APM are you using?

In the video it is being powered by the plane's battery which is an 11.1v 15C LiPo controlled to 5vDC by the ESC. The board itself is the 1.4 APM and the code is Ardupilot Mega 1.02. I apologize that I did not include that information!

P.S. Thank you all for replying so quickly!!

No I've only powered up inside and never have gotten a GPS lock. How do I know if the MediaTek GPS firmware is version 1.6 or not? Honestly I'm not that worried about it. I have seen people on here have a working 'stabilization mode' without the GPS even hooked up...

Hi Robb,

Thank you for the additional information. The power supplied to the board should be fine, have you tried the IMU tests under usb power? If so are the results the same when you test in the CLI window? (leave the BEC and servos disconnected)

Regards

Thanks for the reply and yes, I have tried the tests under USB power only. I have emailed the problem to diydrones help address and received this reply:

"Hi Robb,

Thank you for all the information and we apologize for the malfunctioning board. I believe that the xy gryo is what is causing the problem. Since the gyro has offset values your plane is trying to stabilize from them. It may be that the chip is offset and not contacting correctly. You would have to send it in so we can reflow and realign the gyro.

I have created RMA #xxx for you. Please make sure you include this number inside of your package. Also, please send me an email when you send it to us. We will take a closer look at it and if we are not able to fix it than we will send you a new one. Thank you and we apologize for any inconvenience this may have caused."

I agree; Robb, You've done a great job in diagnosing a hardware problem (not soldering iron). So yes send it in, the store will take care of you as always!

mine did this (similar elevator movement) when I used the dip switches.  then it went back to normal when i put all the switches down.

Unfortunately all my dips were down to begin with. I tried flipping them all up and then back down again. No luck. I have now sent the Ardupilot and IMU back for diagnostics and whatnot... *crosses fingers* By the way it is rather difficult to type with crossed fingers....

Thank you to everyone that helped me! Support emailed me today and confirmed that the XY Gyro was out of calibration or something and also needed to be reflowed. They tested my IMU afterwards as well as my APM module and have now said that everything is working fine now! Everyone here has been nothing but helpful and I wish you all calm winds and no glitches!

I received the parts back today and HOORAY! All CLI data looks very good now! I am a couple of days away from getting back home to my plane so I can't install it yet. Thanks to all again!!
