Hmmm....I wonder if it is a side by side aircraft. Seems to be too wide for a single seater looking at the width of the centre console.
Looking up “Carbonwacker” led me to their website with a pic of a Stemme S12 retrofitted fitted with Solar Panels.
However, as Mark says, the VNE is so low. Only 109, instead of the usual 140 or so.
Could that be something do do with the solar panels?
