The SONATA 2 is not only the small sister of the SYMPHONIA 2. Because of the higher safety level it can afford a very big extended weight range to offer the pilot or the school more options. The covered lines make it easier for not so experienced pilots. The take off behaviour as well as the roll stability are excellent: a MUST HAVE for a modern wing in that class.
