Only way to do this is by reversing the rotation direction, or the blade angles, in any case, it means there will be a point in which the engine will be thrust-less.&lt;br /&gt;&lt;br /&gt;the solutions for an engineering point of view: make the four propellers to have the blades forward-mounted. Or make the back engine rotate down instead of up.&lt;br /&gt;&lt;br /&gt;picky_bastard mode off&lt;br /&gt;&lt;br /&gt;very nice designs btw!</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/388617096954836658/5437071967828694785/comments/default/4988727542388598216'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/388617096954836658/5437071967828694785/comments/default/4988727542388598216'/><link rel='alternate' type='text/html' href='http://www.robertdraws.com/2009/03/blog-post.html?showComment=1244472835538#c4988727542388598216' title=''/><author><name>Anonymous</name><email>noreply@blogger.com</email><gd:image xmlns:gd='http://schemas.google.com/g/2005' rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img1.blogblog.com/img/blank.gif'/></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://www.robertdraws.com/2009/03/blog-post.html' ref='tag:blogger.com,1999:blog-388617096954836658.post-5437071967828694785' source='http://www.blogger.com/feeds/388617096954836658/posts/default/5437071967828694785' type='text/html'/><gd:extendedProperty xmlns:gd='http://schemas.google.com/g/2005' name='blogger.itemClass' value='pid-1192239705'/></entry><entry><id>tag:blogger.com,1999:blog-388617096954836658.post-6499576130096172184</id><published>2009-03-28T16:22:00.000-07:00</published><updated>2009-03-28T16:22:00.000-07:00</updated><title type='text'>Beautiful draftsmanship!

Quick point: the rear props would be pushers, so the nacelle should rotate in the opposite direction for landing thrust?&lt;BR/&gt;&lt;BR/&gt;Love the faired-wing stance of the lower concept, but the language of the top is more villanous..
