  • Compatible with non-pro mz24?

    Is this compatible with thw non-pro mz-24?

  • mz24-mz24pro

    is it possibe to uppgrade the mz24 to pro?

  • Problem firmware


    I have two issues with the mz-24 pro.

    The first is of little importance, the sound when starting is cut sometimes.


    The second, and much more critical ... when trying to set failsafe on channels 11 or 12, a system reset occurs.


    This second incidence has been reproduced in another mz-24 pro. So it's a generic problem.

    Hello Marco Castro,

    I would like to inform you that we know this bug and with the next update the problem will be resolved.

    Kind regards


  • Latest version?

    Ah, I should have been clearer.

    The method they mentioned was one that didn't require the radio to be sent back to you. They implied it was possible to self serve the update.

    Is this not the case?

  • mz

    this link for MZ-24 upgrade to PRO is not a solution, nobody wants to send their radios anywhere. When will you release standalone update software that we can download and just run the update?

  • Answer "Latest version?" & "mz"

    Hello Andy and Gigi,

    at the moment the update is just possible directly at the Graupner service department in Germany, Switzerland, Italy and France.
    It is not possible to buy the update at our Online Shop but also thank you for the idea and we will look what we can do in the near future.

    Kind regards


  • update

    Hello, tell me when there will be an update from mz 24 to PRo. Not the most correct approach of the company to make software updates paid, you can charge for accessories but not for software. I would very much like to put an update on mz 24 to pro. I await your soonest reaction!!!!!!

  • Answer to "update"

    Hello Mr Slava,

    the update from the mz-24 to the mz-24.Pro is available and can be occur at the Graupner Service departments in Germany, Italy, France and Switzerland.
    The update costs 50 Euro and you will get a new radio controll software with new and great features. The following updates will be free of charge again.

  • Missing options


    Now my MZ24 is updated to from pro here.

    I still missing some options what other brands have.

    -Edit throtle curve whitout swich them on (no using throttlelimit).
    -Timer trigger ch 6. Like if there is -98% thrtole timer goes on and under that stops


  • Answer "Missing options"

    Hello Rauno,

    enclosed the answers.

    -Edit throtle curve whitout swich them on (no using throttlelimit).

    Sorry, in the Graupner radios the limiter function is needed for this.

    -Timer trigger ch 6. Like if there is -98% thrtole timer

    This can be programmed.
    Move the CH6 in the clock menu clock start and set the wished starting position with enter.

    Kind regards


  • Timer trgger ch6????

    How? There is just sw options. And cant be changed manually. In heli mode throtle is not controlled by stick, it just straight line ex. 80-80-80.

  • Answer to "Timer trgger ch6"

    Hello Rauno,

    it just works with the support of the limiters. Unfortunately, we do not have an 200 Software entrance.

    You can trim the curve with a trim DT1 or DT2 on K9 (phase dependent) and free mixers in the K9 of 6 in the different flight phase.
    For further detailed questions please get in touch with our service directly and not via the update blog.

  • Update 2.024

    1. Issue with auto time off. Once the auto Time off gets triggered you are not able to cancel it. It also appears to ignore the fact your are currently using the tx.
    2. Please can you tell me if there is a way of changing throttle curves with a live model? other brands allow this.
    3. Please can we have a way of assigning to adjusting the screen brightness, same as you have now done for voice alerts.
    I have just upgraded two of my original MZ24 to this new firmware and am loving the new features.

  • reversing throttlecontrol

    Dear Graupner,
    When I reverse the throttlecontrol(we fly airplanes:throttlestick in front is throttle closed) by changing the endpoints in the throttlecurve(like the usermanual says), every program function in relation to the throttlecontrol works fine only the trim will not work in a reversed way. Is this a bug?
    For the rest the TX is easy and quick to program, a lot of handy switches and proportional controls, lays steady in the hands. That´ s why I switched to Graupner.
    Kind regards from Belgium,
    Tom Corstens

  • Answer "reversing throttlecontrol"

    Hello Tom,

    thank you for your comment.
    It is no bug. Unfortunately it is otherwise not possible at the mz-24.
