SV-2 - Homebuilt single-seat helicopter. Looks kind of similar to Hillberg's SkyShark.
SV-3 - Two-seat helicopter with 360hp Vedeneyev M-14P 9-cylinder radial engine from the Yak-18T and various other parts taken from the Ka-26.
SV-4 - Single-seat helicopter with 140hp (104kW) Avia (Walter) M-332 four-cylinder piston engine.
SV-7 - Single-seat helicopter with radial engine. (what kind??? Same as on the SV-3?) Has been seen used for agricultural work, but I'm not sure if that was its primary purpose.

He did, and another similar to the SV-3 but without a radial engine. These are still a mystery to me as well.
That's actually what I was referring to. Are you saying there is another open-airframe design by him? Can you post it?
SV-1 - this was not a helicopter, but a small propeller-driven plane with a 50 hp engine.
Sverbil also talked of an SV-4 but I am not sure if this was a helicopter, or any aircraft at all. He made other vehicles in his shed like a mini tractor and a car, so it might have been one of these.
The nice thing about egotists is that they don't talk about other people.======================================================Count Hermann Keyserling once said truly that the greatest American superstition was the belief in facts.
You'll find a lot of info on Sverbil there but in Russian. I attached a pic of the SV-1 and three of his helicopters. One of them is the SV-4 but I don't know which.

We have here the latest in primitive technology.
Internet + Opinions = OMG we are SCREWED!
Thanks for bringing the SV-4 designation to my attention!
The first helicopter is the SV-2 and the third is the SV-3. If the source is correct, then that makes the second one the SV-4, and it looks just like the one in HannetonIII's post.
I'd say that's a mystery solved.

Second! Just updated the list.
