Hi folks,

I finally got to SaveTrim my Hquad yesterday and was a success.

Then I checked for interference using Mission Planner "compassmot"
The results:

-at 10% throttle: 57% of mag field
-at 50% throttle : 151% of mag field
-at 80% throttle: 229% of mag field
:eek:

What materials is best to shield my APM2.5? Foam? Plastic? Wood?

I plan to re-wire my red & black esc wires.  And plan to move APM higher on the frame.

People, new questions and topics should be posted as a new discussion above, the comments section down here makes it very hard to keep separate topics going at once.

I typically rely on a battery low voltage indicator which alarms at around 10%. That is where i have considered low voltage for landing. At any rate i don't typically use the low voltage fail safe. Maybe a problem long since solved but it used to not work so well and would trigger if I looked at it funny. For mapping these various fields I have been trying to optimize for a return at around 10%-15% remaining. 

  BTW we figured out the GPX.log file for overwriting the GPS info to the exif data.

@Rob J I don't agree- 40%-50% seems way high for a fail safe initiation. In my experience my voltages don't start getting low enough to bat an eye at until 20% at most.
Comment by Rob J on May 26, 2014 at 8:41pm

40% should have caused a land action to occur...check your parameters and see if you don't have a land command to execute at low battery failsafe.  40% should activate failsafe.  You can't take a battery to zero.  Most people won't fly past 50%

so we were running some flights over some farmland the other day and a couple things came up..

  • The flight plan was executing smoothly when about halfway between two waypoints the aircraft started to descend at an alarming rate. Battery power was at 40%. Have begun looking through the .log files , but am still a bit new at analyzing the log files.could help me see what caused the unexpected loss of Alt. I think it may have been a WP ALt command but all my waypoints were at 45 meters.
  • Was also trying to figure out how to inject GPS camera locations where the relay was triggering the camera using the relay command from the RC9 pin. The " Goetagging Photographs" wiki page suggests only the tlogs can be used, Do these locations record anywhere else?

Thanks for your help

BustamyTool... the pins do not need to be in place.

There are two flavors of power modules... the kind that provides 5v to the APM along with the voltage and current readings... and the kind of power module that only reads the voltage and current but does not have a BEC and therefore does not send 5v to the APM.  It sounds like you have the kind that only reads voltage and current but does not have the BEC in it.

Im trying to build a Y6 and im on my 3rd apm board. I wont go into detail but here's my prob. The board powers up when connected thru the usb but I just tried useing the power module to power up and it does nothing. My question is do the header pins for the jp1 jumper need to be soldered in place? I dont mean the jumper itself just the header pins the jumper connects to.

I have no idea why it would do that. You might send Jeff (on that tutorial) a PM and ask him. He has helped me LOADS!!!!

Comment by Sean Headrick on May 23, 2014 at 2:24pm

That was the ticket!  Thanks On a related note, you are required to use the "relay" triggering method for this application. However , each time I connect to the APM, that specific param reverts back to "servo". I have not noticed this with any other param, and don't get why it would always revert back.
