    Hey all - after finally receiving my backordered FatShark goggles and having a jolly ol' time flying around, the need for an OSD has become quite apparent.  Luckily I had already purchased the MinimOSD a few months earlier.  I tried config'ing it but received what appears the be a common problem of not being able to speak to the bootloader.  I followed the information found here and here, checked this out and also this.

    I did see that I needed a FTDI cable to speak to the MinimOSD and upload a bootloader so good thing I already had this cable.

    However - still no go.  Would someone that has had success with this kindly let me in on something I may have missed via here or PM.

    Many thanks,

  • Thanks Randy

    Your suggestion worked. I loaded AC2.9.1b to my APM1.4 and my Quad is back to flying.

    You aren't seriously thinking of flying without an R/C controller, are you?

         On the mission planner's firmware screen you will see a Load Previous Firmware link on the bottom right.  After clicking the download select an entry that has "AC2.9.1b" at the end

  • How I can get software version : 2.9.1 for APM 1.4. It is no longer supported. 

  • Depends on your software version: 2.9.1 - yes, 3.0.1 - no.
  • so I have been away for awhile is the optical flow sensor supported on APM2.5

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.
