      hi there ,
      i recently build 5" quad with voxl Flight
      setup is : 5" frame (generic racer frame) airbot Furling32 v1.2 esc's,
      tmotor 2550kv motors.

      all pix4 params are default didn't change nothing ,
      just when arming and lift the throttle up the drone vibrate very hard and the motors and esc's goes very hot.

      i tried to change pid settings but it seems that nothing have impact on this behaver .

      i took another quad i have same frame motors and esc's but with another FC and it flying smoothly without changing anything same version of px4 and same params .

      any help or guidelines will be much appreciate,
      thanx in advance
      ben

        Hi Ben, Flight Core ships with a very slightly modified PX4 v1.11 (details)

        Assuming the motors/props are mounted securely in the proper rotation, you may need ESC calibration?

        The Flight Core does not deviate significantly from a normal Pixhawk, so it's tough to imagine anything too exotic occurring. Can you try to put the other flight controller on there to eliminate any differences?

          I'm working with DSHOT protocol and i don't have option to perform esc calibration through Qground control because i cant power up the voxl flight with usb power as you mention on your link.
          i also read that using DSHOT doesn't require ESC calibration ,did i got it correctly?

            That's true regarding dshot.

            Have you spun each motor individually to make sure they are wired correctly? This still sounds like an assembly issue

            Can you share a video?

              so we find the problem 🙂
              it was the rubber dumpers that we put to hold the voxlflight , it seems that they were too soft and added vibration to the board .
              we took them out and the problem solved.

              do you have recommendation about required suspension/vibration absorber for the board? or there is no need ?
