Thanks Weaver,   nice to see they got it working, but I think it may be a bit of a learning curve to get ti flying well  <_<
the things you learn, give your mind the wings to fly, and the chains to hold yourself steady
take off and nuke the site form orbit, nope, time for the real thing, CAM and gridfire, call special circumstances. 
wow, its like freefalling into the Geofront

Very clever.  :thumbsup:

I recall there was a full sized ship that used the Magnus effect to propel itself like that way back in Victorian times. I suspect a lot easier to do that with a ship only in 2 dimensions than with an aircraft working in 3!

Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

Not Victorian, 1920s: https://en.wikipedia.org/wiki/Rotor_ship

Flettner moved on to an aircraft design too:



What immediately struck me were the aircraft control issues. Realistically, the only control you can exert over the 'wings' is to vary their speed, but with a large spinning mass in a full-size aircraft, inertia means that they won't change speeds quickly, and there's also the gyroscopic effects to consider.

This four-rotor design seems to me to have more practical potential for a variety of reasons:

It's generated plenty of fanciful artwork over the years though  :rolleyes: :mellow::
