  • @Mark
    I had this problem before exactly in you video.
    Copter was config for hexa instead of a quad.
    Check the configuration in CLI.
  • yeah, I just went back to the soldering board and tried to solder it again. It looks find and I am almost certain that the TGY 9x is pushing it out. It works with a KK2 as AUX. Anyway, I took it out again with high hopes and it just dug into the dirt (same sas below only I actually let it go). Sold have filmed it but didnt have the camera ready. Anyway, not sure what to do now. Thanks guys.

  • @mark

    make sure you have define aux-ch at your radio, and do radio calibration again.

  • Well, here is my first attempt at doing a hand test. I dont have anyone to help right now so I am trying to just demo this by watching what it does from the ground position.

    If I was to give it more power it would just fall to its back side and grind into the dirt (this is what happened several times yesterday)

    I am assuming that it defaults to stablize mode as I dont have a channel 5 switch working at present... lemme know what you think. Thanks in advance.


  • @Mark,

    That may be old I think, this is new:


    This is the Wiki page for Arducopter! You will find systematic and clear instructions here.

  • @Wessie, thanks for the tip... Just googl'd it and got: http://code.google.com/p/arducopter/wiki/AC2_Preflight    ... Going to try this out and see where I get.

    Thanks all!

  • @Wessie, I have done nothing other than do calibrating the esc and compass. Please explain as I am super excited to get this copter off the ground!

  • @Mark

    Sounds like you need to do the Hand tests now. The hand tests consists of 2 parts, the stablilse test, and the control test.

    Have you done this yet? If you are not sure, let me know and I will explain.

  • Yes I have used retract landing gear on my HEX. I only use one, that retracts out of way of camera. The other two legs are normal for stability. I tried 2 retracts and legs were too wobbly. It takes two legs at least to be stable.


  • So thanks to this group I have the Arducopter almost ready to fly. I now have it getting power, have calibrated the ESCs... and I have already tried to take my first flight.

    For some reason, I am no able to calibrate the 5th chanel on my 9x tgy radio. Oh well, do that later as I assume it will just be in stable mode when I attempt to do a fist flight.

    I gave it a little power and then it seems to power up it self to take off mode (even though I only have it on 1/8 throttle.... is that normal?

    Anyway, once it get to the point where the motors are spinning really fast, it just starts to fall backward ... then I take the trottle down and try to catch it before it eats the dirt (again).

    The gps is working perfect, the power is great, I have all of the tgy 9x controls (except for throttle) down to 40% so I wont give it too much one way or the other. Is that the right way to do this?

    Sorry to ask so many questions, but I just dont want this thing to each dust or fly away before I even get a chance to have control!

    Thanks in advace all!

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.
