It was the first time for the pilot [[http://forum.mikrokopter.de/topic-1086.html|soldering SMD-components]]. Finally after 2 months investing several hours, MosaKopter V1 had its succesfull maidenflight in the first week of september 2007. Here is a picture of the first MosaKopter: . {{attachment:kelder.jpg}} This model served very well during 1,5 years and I had many entertaining flights. Until the unfortunate crash end of January 2009 due to a pilot error.
