[python] Russian Deltas (Was: Suspension)

1) Can anyone translate the Russian text into English? I'd love to read the commentary. 

Here you go Rhisiart:

2) With the axis of articulation between the front and rear parts of the Russian trikes so far ahead of the hips of the riders, and with positive trail (it seems) has anyone any idea of the PSI effect, if any? Or will Jurgen Maier's A>B or A=B rule apply here to prevent PSI? 

I guess they have noticeable PSI and it also is mentioned in the text.
Search for "run of a mad cockroach".


3) Any pictures of your Python Delta, Jurgen?

And whilst I'm asking for information, can I get more inf/pix about the Python PX5 from anywhere. Do I understand the picture right in the 'Modification and Ideas' section: Is the rider really sitting on the front half of the bike, like with the Kalle recumbent? And how does it ride? 

The rider sits on the rear part just like an ordinary Python. But I
tried to move the pivot 30 cm backwards, thus increasing trail and
making the bike foldable within 2 seconds. But the design failed
because PSI was clearly noticeable. Picture of the PX.5 is here:

Cheers,
Jürgen.
