Thanks Hesham, and here's another Czech project in my last post here:
A few I know of are the HC-3 from 1951, an armed HC-3A and HC-3B, also HC-3T.

There were some armed proposals too.
Another HC-4 concept
From Hesham, the HC-4 from Air Enthusiast, 1972:
The HC-4 went through a series of different design proposals until the final project was freezed. Here they are:
1 & 2. A float helicopter (separate profile and three-view).
3. Another float helicopter with bubble canopy (profile view).
4. A small troop transport helicopter that was closer to the final design.
5 & 6. The chosen design (separate profile and three-view).
7. An alternate variant on skids instead of wheels.
8. An attack derivative tentatively designated the HC-4B.
9 & 10. Two photos of the mock-up.
The HC- series went up to the HC-7 tandem twin-rotor transport project.
Here they are:
1,2 & 3. The HC-5 (early project, final design, 3-view and cutaway view).
4 & 5. The HC-6 (separate profile and three-view).
6 & 7. The HC-7 (separate profile and three-view).
1 & 2. The HC-102 (three-view and cutaway view) which was produced.
The HC-102 helicopter also spawned derivative projects that never came to be:
3 & 4. The HC-103 (three-view and cutaway view).
5, 6 & 7. The HC-202 (artwork, three-view and cutaway view).
8 & 9. The XHC-203 (profile view and desktop model).
*squee* Awesome!! :D
Zilina Vazka was a single-seat autogyro of late 1960s.Similar concept
to the Bensen Gyro-Copter and powered by one 65 hp Walter Mikron
III four-cyclinder air-cooled inline engine driving a two-blades pusher
propeller,it was designed by Mr. Vazka,an engineering student,and
built by five other students of the Transportation Technical Institute
of Zilina.It was unknown autogyro.
Found these in my archives. Apparently a Czech homebuilt project with two-stroke motorcycle engines positioned at the rotor hub.
Any more info as to who built it and when?
Not enouth information, but the name of the builder is Maier.

Well, that's at least enough to create a page at the main site. Thanks!
Can we get this stickied with the rest of the general place of origin topics?
We have here the latest in primitive technology.
Internet + Opinions = OMG we are SCREWED!
Now I have the article about the Maier helicopter. If anybody can translate the text, I please post.

Such a shame Kabomber no longer comes here. He would've happily translated the article for us, once being a very enthusiastic Czech-speaking member.

What a laughable design. Only tip-jets can get away with silliness of the rotor-propultion being located somewhere in the rotor disk!
Dear Princess Celestia,
Today I learned that nopony kicks ass without tanker gas. Nopony!
Your faithful student,Fluttercopter
I personally admire the originality. I'd like to see how far it could be taken if perfected.
here is the flying crane project;
Also Czech early helicopter projects;
Novalovym 1& 2,Tucek 1 & 2,Formanek and Haller;
