  • Yes, I calibrated the ESCs all together then tried again individually.  Didn't notice any change after repeating this several times.

  • @Mark;

    Did you go through the throttle range setup to calibrate the ESC's to your radio?

  • I purchased a quadcopter with Turnigy TY-P1 25amp ESCs.  I should have checked more before purchasing these as I see there are many negative reviews.  Has anyone been successful getting these ESCs to work on a multirotor?  The problem I am having is rotors are not turning at same speeds.  I have not found any way to program these ESCs via the transmitter.  Any suggestions are appreciated. 

  • I'm finding that the pitch channel has to be reversed to have the quad behave properly (stick forward, pitch forward). Otherwise the quad will pitch forward when pulling the stick back, which imho is counter-intuitive.

    Personally I think it's a bug, and so I added it as issue. But if for some reasons it cannot be fixed (apparently the reason is that both plane and copter share the same RC_Channel code) it would be a good idea to say it more prominently in the First Setup page of the wiki. At the moment there is a reference to the fact that you need low pwm to have pitch forward, but it's not very visible and not obvious.

  • Yea.  Maybe I will stick with my quad.  I haven't really mastered it yet.  Probably never will but I think I will stay with it and see what I can do.  Thank you Richard

    Hi Bradley,
    The Hex is more stable and it can lift more weight. But the Hex is more work and expense. If you crash the Hex you have youay have more parts to replace. With Hex you have a bit more tuning since you have the extra motors and ESC. I own both a Quad and Hex. Both are a joy to work on and fly. If money is not a problem, go with the Hex. If you want to save money and learn, start with the Quad.
    Hope this helps.
    Merry Christmas,
    Richard
  • I have a 3dr quad and was thinking of buying upgrades to get it to the hexa.  Are the hexa's more stable and little better to fly?  I was looking for some pros and cons.

  • Ditto on the same setup, 3DR Hexa-B, 11X4.7. I encountered the same clearance issue between two of the props. What worked for me was to loosen the two arms slightly, shift them apart, and re-tighten.

  • This is the same set up as I have and the 11x4.7 fit fine on mine. You may want to reach out to 3dr or udrones and ask them what is up. It would be nice if they provided some type of guide for the set up even when they are RTF but i guess thank goodness for the community. 

  • p props in correct location now.. clearance still an issue

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.
