  • Bluetooh headset


    With version 2.0.17, on the mc-32 pro, when you turn the transmitter off and on, the bluetoothh headset does not pair.

    You have to do it by hand.

    I tested it with two headphones, one samsung and s530 (chinese).

    Our technical department will check this.

  • Voice Announcements

    Thank you for this great enhancement, keeps Graupner up with software developments in radio control.

  • Release date


    Do you have an estimate on when the new version will be release to market?

    Is there any bugs that might bring the plane down, or is this a "safe" beta?

    Kind regards,
    Trond Dalsveen

  • Answer "Release date"

    Hello Mr Dalsveen,

    until now we know only about one bug in this beta firmware.
    You should not use two mc-32 in wireless teacher pupil mode. You may use the mc-32 with other Graupner radios in teacher pupil mode without problems.

    At the moment we can not tell you exactly when the final version will be published.

    Kind regards

  • mc-32

    I did make the uppdate whit no problem but now there is a problem whit all the servos on my transmitters ex if a throttle up the servo will go upp to the middle off the curve then it will go back on its first position .so the servo will first go upp the go down ?
    what has happen to the transmitter ?

  • Answer "mc-32"

    Hello Kenny,

    I have a question to your problem. Does your servo go up and down just if you switch on your receiver or during the operation.
    If the problem is during the operation than your servo testing is active.

    Kind regards


  • mc-32

    Hi, that's when I use the radio controls as the servon moves in half a motion. they can not do the whole movement but go back after half a row

  • Answer "mc-32"

  • new firmware 2v018 + Audio files (ES)


    The file “Voice_3_ES.vdf” display message: Voice Data Version Mismatch. Please, check it and solve this bug.

    With my MC-32 updated with the file "mc-32_2v018_ES.bin" I can read in the Main Menu a option: Anuncian, and it should be: Anuncios, or better yet, the correct word is: Locuciones.

    Thank you in advance.
