  • Throtle edut

    Radio is great but,

    You can't edit throtle curves without swiching them on. You have to put that flught mide on waht you want to edit, and same thing in gyro sens. Allways have to power off you heli and then edit.

  • Answer to "Throtle edut"

    Dear Rauno,

    thank you for your message.
    With a correct fail-safe setting, the model would not have to be switched off!
    HF OFF would then suffice. Or, for example, a phase-independent motor stop.

    Kind regards


  • Throtle edit

    Yes. But it not safe enought to leave 10kw heli without rf. I knew all failsafe etc., but all othet brands have "manual" choise the curve what will editetd.

  • Query updates

    Hello I have a transmitter MZ-24 hott, and I would like to ask whether you plan to do this transmitter menu translation into Czech Thank you

  • Throtle edit

    Its not safe way to swich RF off. 12kw heli without rf is dangerous. It would be great feature to every fuctions if there is box to choose flight mode, not whitced them on.

  • Answer to "Query updates"

    Hello Roman,

    unfortunately the mz-24 have no transmitter menu translation into Czech.
    It is also not in planning.

    Kind regards


  • Answer to "Throtle edit"

    Hello Rauno,

    Let's why it's better to use the limiter or motor- cut off function in all flight phases.
    Please try without motor pinion first for the correct function.

    Kind regards


  • Throtle edit

    Well you dont understund. I lnew every fuctions very well indeed. If you are in flyfield and want adjust same parameters with your plane. I dount remove pinion on field. I knew my setup very well.

    Please do same changes in the software. Everyone will like thoses.

    -Release timer1
    -Release ch12 from throtle limit
    -change values without swich them on


  • 11ch MZ24

    Il peut faire la mise à jour de votre radiocommande.



  • Update???

    Are you going to update MZ24 anymore? Now you have MZ24pro and only difference is firmware. So is there plan to have soe fixes and update (ex timer and autolog off) to MZ24?

  • Answer to "Update???"

    Hello Rauno,

    The continuous integration of free new features and features brought the mz-24 to your limits and made it necessary to create a completely new software interface for the mz-24 PRO. Therefore there will be no further update for the mz-24 just the upgrade to the mz-24.PRO

    Kind regards


  • Latest version?

    Is this the latest version of firmware for the mz-24? When I do the "auto download" from grStudio it d/loads a v1.052 file but that fails to upload to the TX.


  • Anwer to "Latest version?"

    Hello Andy Dix,

    please do not update the version v1.052. Therefore you need the GR_Studio 4.7

    Kind regards


  • Mz24 wireless training

    1.042 has a issue with training. I have two mz24 with firmware 1.042. When training a helicopter / fw the throttle goes to -150 Please advise. Plus is there an option to adjust screen contrast and volume by DV pot please

  • Answer to "Mz24 wireless training"

    Hello Craig Reynolds,

    thank you for your comment.

    Please check the servo path in your transmitter. It sounds that the channel 6 is adjust with 150%.
    Second question, there is just one option for the sound volume. Not more.

    Kind regards

  • 1.052

    Hello Davide,

    the update version 1.042 is the official update and the 1.5.x is the online update to the mz-24.Pro

    Kind regards


  • MZ24 forgotten???


    This system is not user friendly. Why you stop updatibg MZ24? It is NOT solution to pay for pro software! You made to same radio mz24 and nz24pro... only differense is firmware and colour. It not good idea to collect money for updatig allready payed system. Release update to mz24 to everyone its going to be easier way to everyone, even for you. All other brands take care of they custoners, but you just say pay more.

  • Answer to MZ24 forgotten???

    Hello Rauno,

    thank you very much for your comment.

    It is not just a normal update from the mz-24 to the mz-24.Pro. There are so many new features like
    - new manu structur
    - additonal model types
    - user-defined voice announcements
    - snap-roll function
    - auto-trim
    and many more.

    So it is more than a normal free update. It is a upgrade to a "new" radio control.
    After the upgrade the following updates will be free of charge and you will be able to proceed them yourself

    Kind regards


  • Yes, but

    This kind update is normal update in all other brands. It totally normal add new features and graphics in new firmwares. Or do you think its normal pay if there is some new features? You should listen more users!!!!!!

  • Answer "Yes but"

    Hello Rauno,

    thank you for your answer.
    The voice of our customers are very important for us and we give the advice to corresponding department.
    Anyway we can not offer the update to the without fee.

  • Answer "1.052"

    Hello Davide,

    The version 1.052 was not tested and released.

    Kind regards


  • MZ 24 update to Pro

    I am very disappointed that you the ordinary mz-24 no longer support and ask money for updating to a mz-24 Pro version.
    After all you have made use of the comments and suggestions provided by the MZ24 users to build a new version.
    Here too, are added costs because the transmitter has to be sent to you.
    All this is in my opinion not necessary because this is also possible via a normal online update.
    This does not require any hardware procedure in the transmitter and should be for free in my opinion because the cost of the new software back deserves to be by selling the MZ-24 Pro transmitters.
    Can you tel me how I can get the online update to the mz-24 Pro ?

  • Ok I want to pay for update PRO but!

    Hi I'm Stefano and I have a MZ-24.
    Ok I want to pay for PRO update but why must I send the radio to the service for a simple software update? Why can't I buy the software on-line and update my radio at home?
    My radio works very well and I don't want to ship it to the service with the risk of losing or breaking.
    So please, let us update the radio by purchasing the PRO update on the web site.

  • Answer to "Ok I want to pay for update PRO but!" & "MZ 24 update to Pro"

    Hello Peter van Hout and Stefano,

    thank you very much for your comment.

    At the moment we can just offer you the update from the mz-24 to the in our service departments.
    An online update will coming for further updates.
    The only way for the update to the is to send the radio control to us.

    @Stefano: You can also send your mz-24 to our service department in Italy.

    Thank you for understanding.

    Kind regards


  • Comment to Graupner answer on: 17 August 2017

    What you are saying is not true:
    "The only way for the update to the is to send the radio control to us."
    This is what you wish to do so and not the technical boundary.
    Can you tell me why the online upgrade is possible at Graupner USA and not with the Graupner EU?
    You would at least can make also like your USA colleagues, supports the online update.
    My opinion is that you are obligated to you old MZ24 users to provide the best possible service so that we also in the future wish to go on further with Your Graupner system.
    The way you leave the old MZ24 users with software that is not error-free and not further supported is not a correct way to fix this by forcing them to buy an update.
