Just to inform you that some sections (balance and weight!) of your replacement aircraft.cfg from the Mlj31fs9.zip file are probably wrong. For example both replacement files (for HJG and for Sanchez models) state
Sorry for this delayed answer to your message. Because of the HJG release last week and several other things it was very hectical and I had no chance to post here sooner.
Thank you very much for the hint with the wrong weight. That's absolutely correct and I will change this with the next version.
