  • Hi All I am having a problems taming the throttle on my hex. I'm new to the hobby so bare with me on this but while on the ground tuning if i up the throttle about a third and stop the motors continue to accelerate on there own quite a bit more in a slow build. Dropping the throttle does not immediately slow them until i,m down at 0 throttle. As you can imagine testing in flight has given me some real grief! Any ideas would be most welcome. Is the problem with the ESC's or the APM settings?

  • Funny thing happened to me yesterday. I have a fully fuctional APM 2.5 qith NEO-6M. Every mode is tested and it works. But for some reason i activate LOITER, it worked for like 10 sec, and then it shooted in a direction until i activated STAB mode again. I'm running 2.9.1b. Should i go through the logs and be worried?

  • Hi Jani,

                  Sorry , You are quite right. It was not an year ago but long back perhaps more then two years. My bad. Sorry. Time flies.

                   Thanks for your prompt reply. I am looking at a stable hover with GPS and altitude hold , auto take off and landings + auto landing on fail safe  for Quad. I am comparing the same with DJI NAZA. Ofcourse the cost of NAZA is high but I am looking at the features. I saw NAZA performing well for all above requirements. I am looking at Aerial photography application. Will it perform at par with NAZA ? Does it have auto home location storage feature on power on ? Can I use the same without a computer and a modem in the field ?

    I already have MediaTek GPS. Do I still need to buy one ? If I need to buy something additional for better performance , I do not mind.

    Kindly guide me so I can proceed further.

    Thanks n regards.

  • I think in all fairness since its very conception every release is a pre release its forever changing the numbers are just mere reference for builds some might work for some and not for others

  • Randy, Thanks for the update on 3.0 release.

    When is the final release trending towards? I'm just a little hesitant to try a pre-release build.

    Sid, i really doubt that it's year ago. it's more like 3 years ago.  jDrones was separated from FahPah at end of 2010. If you log on store.jDrones.com you should find your earlier order from there. 

    True current software does not fit anymore to 1280 CPU board.  1280 CPU board was announced to be End-Of-Life on software support over 1 year ago. You can still manually compile software that fits on it but you need to disable many features to make it happen.

    I suggest to upgrade at least your main CPU board or whole flight electronics to get future updates.

    or whole new APM2.5+ electronics

  • Hi I had bought the APM hardware one year back from Fah-Pah , Thailand and succesfully flown the quad. I see a lot of development since then but I was occupied with my personal issues. I am back to my passion now but while trying to upload the latest version i.e. 2.9.1.b it says firmware too big for 1280. Please upgrade your hardware. I can understand the same but is there a way out or do I need to buy the new hardware. I can not shell out more money at this point. Is there a way I can use the tested firmware which can be used on this hardware ? Pls advice. Thanks. SID

  • Thanks Bill I might just do hang out for the Taranis.  I fly lots of Scale models (plane) and the Aurora is my main radio. I think buying a dedicated radio would be the right thing to do.

    @john. Your HiTec will be perfect. If you want to buy a new TX though wait for the Taranis from FrSky. It uses Open9x firmware so is awesome for drone use. And it's only $200!

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.

Valid values for Mavlink SCALED_PRESSURE

I have a raspberry pi reading mavlink messages from a pixhawk. When I read SCALED_PRESSURE I get hPa values around 490  - less than half of what I would expect - and a temperature around 4834 in cdegC - seems warm to me. This is consistent with what is shown in Mission Planner (see below). Is this normal or is my barometer on the fritz? I am trying to calculate my own altitude like AP_Baro::get_altitude_difference but in a companion computer.
