"@Michael - Thank you for the info.

To clarify, I held a large PCB (computer motherboard) in between the ESC and the aircraft. The motherboard appeared to shield the APM from the ESC and eliminated most of the drift in the servos. Also, the drift is…"

"I have a weird thing happening, and I appreciate any insight that anyone can give.

On one of the testbeds I am using to test the APM, I am using a pretty heavy duty, high voltage speed controller. It appears that the speed controller is causing the…"

"Chris and Michael, thank you for the info about upgrading to Arduino 0019. That solved the compiliation error relating to the stream.h library."

"@Chris and Michael
I got the libraries via svn checkout of the arducopter trunk you gave. Now I get a compilation error of a missing file called stream.h. I searched through the libraries and the file is nowhere to be found. Do you have any…"

"Chris and Michael,

Thank you for the info. I will check those places. I really appreciate it."

"Another quick question... In the latest code available for checkout, there is an include for FastSerial.h, but I cannot find it anywhere in the libraries.zip or on the svn trunk. It is causing a compilation error because it is missing.

Is there…"

"I am attempting to use my APM on an aircraft powered by an IC engine instead of electric. The vibration from the engine seems to be affecting the sensors on the APM. For example, when the engine is throttled up while the aircraft is stationary and…"

"Does the latest code from the SVN trunk require some removal of comments to enable communication with the uBlox GPS from the DIY Drones store?

I can get the GPS to communicate fine using the older 1.0 code, but not yet with the new code.

Just…"

"Also, adjusting the reverse_ch1_elevon and reverse_channel_2_elevon values between 1 and -1 cause things to stay the same or they make it even worse."

"Has anyone noticed bugs or problems with the elevon mixing mode, or is there a configuration we should be aware of?

When I run stabilize mode with elevon mixing turned off, the servos respond correctly to stick inputs.

But when I turn on elevon…"

"Is there any info available on how to properly configure the elevon mixing, including how to properly set the trim variables? I have tried with it being enabled and have then experimented with the various reversing settings, and the output it not…"

"@Earl

I noticed in your serproxy cfg that another line is missing that I have in mine by default.

# Transform newlines coming from the serial port into nils
# true (e.g. if using Flash) or false
newlines_to_nils=true"

"I just figured out why the GCS would not read the data from serproxy.

I had also change the net_port3 settings (COM3 in my case) to = 5331.

Now the GCS is reading pitch and roll data at least."

"Are there different flash patterns on the C LED on the Mega IMU Shield and what do they represent?

I have my UBLOX GPS module connected and the C LED is flashing a steady red."

"@Earl
You might try changing the "net_port1=5331" to "net_port9=5331" and then try to telnet to the 127.0.0.1 5331 as Jason suggested.

@Jason
I was successful in establishing a telnet session to the serproxy and seeing the same output as the serial…"
