Here are first two pages of info I still have by Alexander M Lippish.
I always liked his approach to this subject.
This is from an AIR TRAILS magazine from 1950, so some experts may find fault.

And page 71?

It is a long article - also continued to the next month -- I have all of it and always liked it - The guy made good sense .
I could copy it all and put it on my own web page if anyone really is interested .
I always thot someone would to refer to it but --------------

Hi Dick,

That's interesting stuff.
Could you show us page 71?

The article is quite long (actually going two months) - I guess I will copy all of it and put it on my web page and link to here --to avoid cluttering up the RVUniverse site..
Lippisch is/was a hell of a lot smarter than me - and frankly -is where I got a lot of my ideas from .
I don't blame him for my intrepretations tho----------

Hi Dick,

Is there any progress in copying the article?

Thanks,
Yuri Kuznetsov

I should have it by this week end - been busy
