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

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.

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
