The receiver software 7a04 is a Beta Software for the radio control mz-32. Our test pilots have carried out numerous tests with the mz-32. During extensive range tests on the ground with the mz-32, a problem has sometimes arisen that first needs to be investigated in more detail. The software can be used in truck function models. Use in flight models is only permitted after successful extensive range tests. Alternative version 3a71 is available. In case of problems with the range test, please send a log file to our Service to email.
