Thanks Hesham. I did not know this work of Gedovius concerning the Pa.101. It's Added too in the answer of Le Fana that the wingspan of the 101 was a little bigger than the wingspan of the 100.

Has anyone done any analysis on the SP 190 and SP230? While at first glance they look like they'd have to fall into the sky to fly, more and more I wonder if they might just have been reasonable flyers, if a tad squirrelly. Especially the 190 as a battlefiled medevac.  B)

Good question.

If it's such a good question, why hasn't anyone asked it until I just did?

There are aspects to the 190 that I'm curious about, such as two wheels per main landing gear side. And, as I have the Unicraft model(actually both the 230 and 190), where on the 190 was the radiator supposed to be mounted?

I know that the SP-190 was basically a paper plane(never left the drawing board), it does have the look of a potential successful flying machine, if only something of a squirrelly handful, but then, as a battlefield medevac, it'd have to be able to fly evasively when called upon to do so.

Besides which, I always had a very soft spot in my inner heart for such strange-looking beasties. I am even quite partial to the M-15 Belphegor.  ; B)

The patent 729528 (inline engine), the SP.230 (radial engine), the SP.240 (radial engine) and the SP.190 (inline engine) where among the first drawings of M. Payen's projects (and among the first delta wings, or "ogival" wings in these cases, projects).
It's difficult to make a good answer for your questions. Some modern fans of Payen have built flying models to find answers for their own passions among the Payen's projects. But nobody made the three "ogival" SP or their patent as flying model yet.

For the radiator of the 190, there is nothing. But on the patent 729528 (inline engine too) we can see a radiator air intake on the upper right part of the engine. Surely, if there had been  a development of the 190, there would have been an air intake somewhere around its engine. But today, we can only make assumptions... :-\
