Recent FLIGHTmagazine and pusher pusher story by Peter Garrison made me think if a pusher is a "dead end" after all.

I have been very keenly developing a pusher design during last 8 years and last 5 months actively.

I got the impression tractor is more efficient if you have fuselage dia more than 50% of the prop dia.

Did anyone read the story ?

Pushpull Cessna is know to be 33% more efficient ( climb rate ) when running with pusher prop alone than in tractor mode.

The drag and turbulence and several other factors were mentioned but seems that real comprehensive data is vague. Is pusher technology still like a new frontier in aviation ?

Also the Piaggio Avanti P-180 loud noise was mentioned.
