  • Sorry to trouble you all again.
    I purchased some Dys BLheli 30a esc to use on my 220 quad build but i think i may have overlooked the fact that i cant flash the firmware using Kiss Fc..

    Is there anyway round this?
    Do i need to flash the esc';s at all?..

    Or is this just a costly noob error, maybe best fixed with a new Fc? :(

    Thanks in advance.
    Martin

  • Should be able to just calibrate them in betaflight/cleanflight,doubt your doing anything special bar normal fpv flying so the fw on them should be identical so just calibrate them in motor tab after you do the build.

  • How would i connect them to the computer?
    Def wont be doing anything more  than simple fpv flying/crashing.

    sorry if this seems like a daft question..

  • When the quad is fully built you connect your fc to the computer and calibrate them in the motor tab,so you do it through fc.

    Is that still possible when using a Kiss fc?

  • Yes absolutely.
    The best way to calibrate escs is from the fc and it I don';t know of an fc that can not do it, you just need to use a protocol the esc understands
    If the are blheli this means oneshot125
    If they are blheli_s this means any oneshot or multishot although you could use dshot and you don';t need to calibrate

  • I love to say i understand that!! lol...
    Obvioisly glad i can do it and dont dont need to buy anything new.
    The esc';s ars Blheli_s..
    So i dont need to do anything other than calibrate in the Kiss fc?
    I do t really understand all the oneshot/mulishot/dshot as yet..
    Im sure i will get there eventuly, thats part the reason i decided to build instead of buy.
    On a quick change of subject, Why do you set the drone motors to be running when it is armed?
    is it purely a visual thing?

  • If they are blheli_s run dshot600 on the flight controller, the escs will work and you do not need to calibrate (indeed calibration has no effect)

    The only hing you can not do without passthrough is change motor direction, to do that you will have to switch any two of the wires between the motor and the esc

  • In config i would set the motors to run when armed,as you can guess its so you know they are indeedcrunning or not running,on the subject of arming,set a switch to arm in the modes page,what handset/tx have you got?

    Once you build the quad,dont worry too much about direction of motors till its all soldered up,then calibrate esc,then check motor direction.to calibrate esc,just hook the fc to cleanflight/betaflight,then go motor tab,test motor tab on,then put motor master slide to max,hook up battery,listen to beeps of esc,when it stops just drop the master slider down,more esc beep confirm calibration.then check the motor direction,set your min throttle,min command and max throttle are set right,keep min around 1000,min command 1000 and max throttle at 2000.theres a better way to set min throttle but only if you need to,more on that later.

  • Dshot doesn';t need calibration and doesn';t use min and max throttle
  • #11 by Saleem on 14 Sep 2017
  • Do the esc have to be dshot compatable?
     :smiley:
  • #12 by Cheredanine on 14 Sep 2017
  • To use d-shot? Yeah mate but all blheli_s escs are
  • #13 by Saleem on 14 Sep 2017
  • Gonna try enabling dshot on my ongoing build without calibrating esc,never tried it before,sounds exciting  :wack0

    I shall be using a DX6 as thats what i have for flying helis..

    Im sure programming that will be the next challenge..
    A little out my comfort zone with this stuff, its easy for me with helis!!
    Throttle hold and idle up is about it.. lol

    I have enabled Dshot600 in the kiss fc software so hopefully i wont to do any esc calibration. :)
