unpacked placed in the sun and worked exactly 1day long ... Bat. umgeschlalten inserted did not work properly ..-- switch the 2nd time from the switch pin canceled .... motor shaft with precision mechanics oil sprinkled ... and lo and behold after 2 days he began to wobble! .... and now flutters after a week still! .... even even when the sun just seems a little! ... Our Teichfrosch even tried to catch him! ... looks funny but technically not quite ready ... but ok for the price
