    @tahines - there are two schools of thought here.  One, go conservative and get an AR.Parot or something like that and practice the difference in control.

    Or two, buy a quad (x4), build it and learn that way.  It's fairly fool proof if you read the wiki, manuals, ask questions and TEST TEST TEST.

    You will of course break things (props, motors, bend arms, etc) even if you are careful.

    Considering you've been around RC before I would probably start with a X4.  That's what I did (making the jump from planes) and never looked back.

    It really comes down to your budget, ability and confidence. (:

    Happy to PM more if you're interested.

  • @tahines if you have no flying time with a multirotor do yourself a favor and get a cheap 40 dollar one to fly with for a few weeks before you even think about flying a arducopter.   If you are just concerned with a "hobby" type setup a quad would work fine. If you are looking to do something more ie bigger cam etc.. Hexa, Y6, X8 but it sounds like that's going to be overkill for you..

  • Thinking about buying a 3DRobotics Copter.  Don't know which one to get (X8, Y6, or X4) with FPV.  This will be my first copter.  I have been flying RC electric planes with small camera a while.  Ready to get a copter.  Anyone have any good/bad info on these units?  This is for hobby and aerial video/photography with a small camera or GoPro unit.  Any help would be useful.

  • @Mark : -

    Test 1:
    Hold the quad securely in your hand, ARM, and advance to 1/2 throttle or so, until you feel it getting lighter in your hand. All TX sticks in the middle. Now tilt the copter in the 4 directions. It should "fight" you and try to remail level. It MUST pass this test. if it feels wobbly in your hand, or tries to go places, this is not right, go check your motor numbering, pdb setup and prop directions.

    If you pass test 1, move on to

    TEST 2 :

    Still holding it in your hand, throttle 50%, blades spinning, mode the Elevator (pitch) stick forward and back, the quad must follow the sticks. Repeat for Aileron (Roll) stick, and lastly Rudder (Rotate). you may need a bit more throttle to feel the Rudder pull, and be careful here. if you push the rudder left, the FRONT of the copter must want to go left. if any of the directions are incorrect, simply recerse that channel on the radio. (Dont accidentally reverse your throttle!!!!!!)

    Let me know the results.

    ALL the coptwers I have set up have flown after passing these test.

  • Can anyone point me to a working ARDUCOPTER Y6 Parameters file?

  • hi,who had used the px4fmu? I made new one ,but can not connect to pc,because when connect to pc ,it can not see the usb com port,and not install the usb drive.who can help me.thanks.

  • I would check CLI also to make sure.
    I think setup - frame.
    When I had the issue I enabled motor logging to see what was going on. I had output on motors 5&6.
    Checked the frame and Bob's you uncle.
  • MR60

    On the first MP hardware screen you select the quad.

    Then on the second screen you select if it is a + or X.

    That's it.

    Carefully check motor spin direction and order.  Do not use super simple mode.  To test, hold the copter above your head and turn on (you don't need hover speed to do this).  Wear eye protection, thick clothing, and gloves.  Apply pitch forward to see if it points down.  Pitch back to see if it pitches up.  Roll left to see if it leans left and roll right to see if it leans right.  Yaw left to see it it goes CCW and yaw right to see if it goes CW. 

    Then if it still acts funny then it is probably tuning and post a photo.  You can also start a new topic so people can directly reply.

  • @randy, 

    Is there actually a way to distinquish a quad vs hexa vs octo  copter? I just saw that you pick the frame type then it has X configuration and all three fall under there. Your suggestion does make sense, but how do I set it in the CLI? Man, if this is the only problem I can start flying this thing right now. THANKS in advance! --mark

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.
