Oh, so many questions.
The one I'm particularly interested in is how the Rotax 912, which is still partly air cooled (the cylinder barrels) is going to behave in a traffic jam.
Oh, and what about the "carrying capacity" of 195 kg? That's two adults, no baggage, no fuel. Seriously?
But I still think it's a load of media hype about nothing. From what I gather from the article, the only reason for this press announcement is that the FAA have increased the weight limit for a Light Sports Aircraft so that this thing will (or should I say "may eventually") fall under LSA rules. But the OP heading "gains certification" seems to be very far from the truth right now.
