Ah, long about the "Twelfth of Never", then?

Naw, naw, any day now. Really and for true. My promise of speed is as trustworthy as a politicians claims.
Ah, the "real soon now" beloved of software developers. :)

No importa, I'll purchase it when it becomes available.  What you have posted might be enough to do something in 1/144 scale.

Early Aircraft Projects / Re: Projects in Switzerland

The same was the case fro the Pilatus SB-2. The completed project was actually sold to Pilatus who then built it (but only once).

Here I have to correct my earlier statement: It was not the case that the project "SB-2" was sold to Pilatus.

The aircraft was designed and developped by the "Studienbüro für Spezialflugzeuge" at ETHZ on order of the Swiss Civil Aviation
The "Studienbüro" signed a contract with Pilatus for the construction, building and testing of the aircraft
The amount considerd for all those works was not enough... and as I understand now, not all the invoices of Pilauts were paid in the end... this may be the reason why sometimes we read that Pilatus had "bought" the project.

Any chance it will not look like a flying wing or cranked kite...

and maybe look more like this...
From where comes the fifth plane in the red circle before the four J-20 ? Is it a fake or an old project or an artist view ?

just a fan made CGI or doctored photo

Propulsion / Re: DB021 turboprop

my thought was to convert an Fw190D over to a possible turboprop version, which got me to thinking if there ever was such a proposal, or even a Ta152.

It is my dream to build or acquire an FW-190D replica and convert it to the most powerful turboprop that could fit, hopefully something in the 4000 HP range. 

A boy can dream......... ;D

Thanks martinbayer friend for the data review and got the name of the same Lippisch "Gleiter Bombenflugze", although it was not official history after the drafts found by the allies after the end of World War II indicate that at least sketches of the concept were made. Luft46 page does not appear in the index but it appears in the search engine ...!

Thank you friend Gray Havoc and complement the data and managed to locate the name of the Lippisch project "Gleiter Bombenflugze"

Here I leave the drawing with the identification and some tweaks ... Now to find the differences ... !!
