Saint Yan, it's not far from my home, it's worth going there.
kézaco the RSA, ULM Blois?
probably this: https://www.rsafrance.com/index.php/age ... el-a-blois
an exceptional reduction of 180 € is granted if the registration is done
during aeronautical gatherings (RSA, ULM Blois). She is still from
100 € if the registration reaches us before April 1, 2023 (and 50 € if it
arrives before May 1).

Yes, these salon discounts are weird...
I will contact Michel Kieffer again, he has been in the association for a long time...

Also, there is a tendency to lengthen the wing, to reduce the chord at the wing tip[/b], but also to install devices there to reduce these parasitic vortices such as fins / winglets.
Found on facebook, this concept that doesn't skimp on winglets
Which in my opinion mixes the good and the less good.
I find that the layout of the wings is interesting, especially at the front where the "duck" fins are very developed to the point of forming almost a normal-sized wing.
The aerodynamics of the fuselage in airplane mode seem to be of good quality.
On the other hand, the installation of the propellers in the wings is harmful; this probably decreases lift in airplane mode in addition to generating turbulence/drag on the wings.
If you have money, here it collects by tens of millions €..., very proud of their aerodynamically questionable project at first glance.

Not even made and already expired: there are double winglets 
I find it hard to believe in the stability and performance of pierced wings...
21 Million, 245 promises of sale based on a prototype that never flew (at least not in the air…)…here is the start-up nation of big mouths that is banding… Macron…

I found this Remundo in a professional equipment magazine, it's in your corner apparently: Fleasy X8ed in flight...virtual!
I didn't know that we could certify on the basis of scale models!!
This allowed me to discover: https://hionos.com/ which looks interesting!

Re: How to properly design a VTOL/ADAV aircraft-helicopter?
yeah the shape of the wings inspires. They are looped, which reduces the marginal vortices at the tips of conventional wings.
This contraption on the other hand is a little strange, it is an "octocopter" whose wing seems to tilt.
But it is above all by its propulsion which in my opinion is a big pipe...
I quote "a turbocharged high temperature fuel cell"...
Not content with this gas plant, the designers added a tank of hydrogen... liquid, that is to say close to absolute zero...
I bow !

Apparently it goes to the EASA!
