  Hi mP1 - unfortunately they are not. Yours have 4 holes. The black ones have only 3. Thanks very much for replying though :)

  Dear All,

  I live in Perth, Australia. This week I broke a prop adapter for a black 880kV motor - this is the piece that is screwed to the top of each motor - you attach the prop to this. It had already been weakened after I straightened it after a crash.

  I am helping out this week on a field trip with a group of botanical researchers in country WA collecting plant material. I was all set to get some habitat footage with my Y6 to help their project. I have some spare motors on order from 3dr but they will not arrive in time. I don't know any place in Oz that supplies these motors.

  This is a humble request - does anyone live in the Perth area that is able to lend me a spare prop adapter for next week? I can happily pay with a slab of beer :D

  Spencer

  Single sheet will block almost all signals, it will also redirect signals so you can wrap a sheet around 1/2 of your wireless router toward your workstation to boost the signal.

  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.

  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.

  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.

  I am a bit new to it, but I am triggering a couple cannon cameras with the CHDK USB connected to the with a turnigy Rx switch. All i am looking for is a high PWM signal. It seems like it shouldn't be this hard. I think I just have some servo or PWM limits out of wack.
