"Hi,

Can I use my own Castle Creation 10A BEC with the Current sensor? Its quite a high quality BEC.

If I do this, will the calibration values you provide still be correct?

This is the BEC I am referring…"

"Thanks Paul.. Ill try try this today."

"I had the same problem guys with my M8N Drotek GPS. Settings I manually changed never persisted even after writing them to flash.

The workaround I found that fixed this was to upload the configuration file provided in the WIKI.…"

"If you are setting the voltage manually then the voltage divider will automatically update. You dont need to change it back to 10.1. My understanding is that you EITHER change the voltage manually OR the Voltage Divider Manually. Changing both is…"

"I had a very similar problem with my M8N & Pixhawk

Here is what I noticed:

1. When indoors and you do not have a GPS FIX and you have the internal compass also enabled you get the compass variance message. Once you get the GPS fix the message goes…"

"Just my 2 cents.

Form the picture you posted the external compass wires run very close to the XT60 battery connector.  You could try re-routing those wires. Also, the External Compass could be moved to the front of the frame. Right now it's bang…"

"Thanks James... That clarifies it."

"I believe that if the voltage indicated in mission planner is incorrect then you need to adjust that value manually such that the voltage in mission planner matches the actual voltage measured by an external device (multimeter).

I don't think there…"

"Ok. I think I understand.

Does that mean that if I mount the compass exactly above Pixhawk in the center of the frame I would get the lowest offsets - Possible near 0? But the drawback of this would be higher interference..

Also - If offsets are…"

"Thanks James. I do appreciate that the values are not all that bad and within the acceptable range however I would expect that with just 1% compassmot interference at least the x & y offset would be closer to 0.

Is there anything I could do to try…"
