I just got my hands on a copy of The Kasper Wing, by Witold Kasper. Surprisingly, the book is still available new(Meheen Engineering in Denver, CO).
It's not a very long book (77 pages), but has some good info that I've not seen elsewhere.
It covers the design aspects of a kasperwing-type plane, as well as some explanation on vortex lift. I suspect that some people on this thread might enjoy it.
For those who might be interested, you can find the contact info on this rather old page (w/ outdated pricing): http://www.twitt.org/kasperminutes.htm
TWITT=startpoin for auer KASPER-wing investigations...(many years ago!)
Some recent video by Kasperwing pilots.
=conter rotating gear for auer (green) KASPERWING...
It looks very nice. Does it run in oil for lubrication?
-the first modell (70 HP) is working with oil and naddle bearings,
but my (on the pictures) should be oil-less=mooving elements will be Diamond Like Carbon coated (Koeff.friction <0.1 !)...
PS=I hope to get from old Z G-25 motor >75 kG
thrust,with direct drived 130 cm C-R propellers...
(with wooden propeller and 3:1 belt gear=50 kG !)
PS2= weight withaut propellers < 1.7 kg ...
=two propellers with axe circa 2 kg.
=2 propellers (1.3m) +C-R gear +mountage tube < 4 kg

Beautiful workmanship. I do wonder how the drive will disipate heat without lubrication.
-without oil lubrication =only future project,iff to replace bearings with DLC sliders...
(it needs very smooth surfaces,at first two "sattelites" will be thrated with DLC technology...
then at first we involwe standart bearings[in sattelite=naddle]+transmission oil)
PS=similar gear was examinated at circa 70 HP=you can hand hold (50-70 Cdeg.)
+big holes in white(alu) tube between big bearigs
Good news, Kasperwing.com will return to the internet soon. A new webmaster and Kasperwing owner has stepped up to maintain the site that has be dormant for a number of reasons.
The kasperwing.com is already up. It is still under construction and reorganizing but there is some new info already posted under 'Technical Library' which might be of interest to someone.
CONGRATULATIONS !!! Thank You...
BTW=I and my Fellow Maciek Konopka (ULS and glider pilot) are the owners
of "GREEN" KASPERWING.
now we are changing classic thruster to the Conterrotatig one with differential gear=moore thrust,less noise !
Thanks for taking over the site.
=kasperwing.com is alive !
