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).

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?

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!

I personally admire the originality. I'd like to see how far it could be taken if perfected.
