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

  • @Spencer

    Ive got a few blue adapters, i just dont know if they are compat with blacks. If they are private msg me and ill pop one in the post from Sydney.

  • 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.
  • Aluminum foil.
  • 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.
  • 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%

Will AHRS_ORIENTATION=8 for Arducopter 3.2.1 on APM 2.5 using a traditional Heli

I have been Reading Chris Olsen posts and watching his videos on Arducopter with traditional Helis using a Pixhawk.I have inherited an older Trex 450 heli with the old Align 3G FBL hardware.  The FBL controller appears to be bad.  So I have an old APM 2.5 without a compass or GPS on board.  I just want to replace the failed Align 3G FBL system with the APM.Now I have to mount the APM under the skids on the heli so the APM will be upside down.I have Two questions.1)  Is the AHRS_ORIENTATION=8…

Maximum number of Lidar for Object Avoidance

Hi all,I'm setting up my PX4-based quad with ST VL53L0X Lidar sensors (I currently have three) and I noticed that line #24 of the current Rangefinder library (here: https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_RangeFinder/RangeFinder.h#L24) has the maximum number of sensors set to 10 (ten). Am I understanding this correctly? And has anyone ever tried to setup this many rangefinders (or anything close) with any measure of success?Any input/advice will be greatly appreciated.
