Those are the plans of the Cicare CH-4.

Are you sure? I didn't look at them too close but I thought it was the Skylark from the Vortech site. I'm not familiar with the CH-4. Could they all be the same?

The Cicaré CH-4 made the first flight on Dec, 1983. The drafstman and seller of the plans, Osvaldo Durana was argentine also, tragically dead on an accident at his home.
His father was a friend and business partner with Cicaré years before the CH-4.
The Vortech Skylark was built from these plans, yes, I'm sure.

Yes, The CH-4 plans were initially distributed, but not sold for too long. I also purchased a set. From these set of CH-4 plans, Joel at Vortech built a 100% copy helicopter, and marketed it as the Skylark kit. Seems like Osvaldo has redrawn the CH-4 plans in CAD, and now markets it as the Furia, but in .pdf format.

As they are basically "freeware", I can e-mail a scanned low-res copy of my set, if anyone is interested to learn more about the machine.

Regards,

Francois

Who draft your set of plans, Francois? was not Osvaldo Durana?

Very interesting. I bought my Dad a CD off eBay for like six bucks. It had your general incomplete plans for half a dozen homebuilts, a bunch of other random helicopter info, and the seemingly detailed and maybe even complete plans for the Furia. Mom said she couldn't get him off the computer for days. All in all it was well worth the six bucks.

Juan, I'll have to check on them when I get home from work today. My set seems original Cicaré, it has a print batch serial number on them as well.

Regards,

Francois

As far as i know, Cicaré itself never sold plans of the CH-4, the only ones are these drafted by Osvaldo Durana, and were made years after the flight of the prototype. Cicaré built the CH-4 without plans, just sketches.

I am almost sure that the Skylark was built using the Furia plans.

Best regards, Juan Carlos

JC, I got my set from them in 1990, while I lived in Chile. Later on in 1991, I moved to the US, where I stayed in Bethesda. I travelled up to Fallston near Baltimore to meet with Joel Levin of Vortech, where I swapped him the CH-4 plans in a trade for a bunch of other plans he had. Not that there is any credit due, but I was rather surprised that it happened this way, Joel must have used that exact set I swapped him to build the Skylark. The Furia set of plans only became available much later, and my set are most definitely not the Furia published set. The title blocks on the drawings are in the name of the Cicaré company, why would Osvaldo include that on Furia distributed plans?

Anyway, they are all copied drawings of one and the same thing, Mr Cicaré's original and extremely novel CH-4 helicopter. A lot of what we see today, can be directly attributed to this masterful little helicopter.

As I have often said, my dream is to have a copy of that original little CH-6, have a look at the little ripper.

Cicare CH-6 in Argentina - YouTube

HeliCycle's, Mosquito's, Rotorway's, Safari's, any other machine you can think of, eat your hearts out !!! Gabor, tell me you are not as horny as hell when you see those torque turn chandelles !! As my kids would say, "it's gangsta Dad"! ...and I would have to reply, "it's just the way I roll..."

My Skeeter Jr. project is as close as possible a copy of this CH-6 that I can figure out, using the Mini-500 dynamic components.

I'll post a page of my drawings in this thread tonight.

Regards,

Francois

Let me ask Fernando tomorrow, I'll send a e-mail to him about this history.

Cicaré built the CH-4 in the early years of the ultralights, thinking that he could fly it without pilot license, but finally, a License for UL was established by the civil aviation, so the reason for the CH-4 faded away. By that time he was working with the CH-5 agricultural helicopter, and the CH-6 was built only to check the dinamics of the CH-5, because the wait for the Lycoming engine for the CH-5 prototype became very long.

The CH-6 of the video was built specially for Gustavo"gato" Brea, the test pilot of the CH-5, and it is a little reinforced, and heavier than the original CH-6, but still fly very well with the Rotax 582.
And the credit is also for my friend Mr. Brea, one of the best pilots here, Air Force officer and veteran of the Malvinas/Falklands war. He can do almost anything with a helicopter, includes loops and rolls with the H-500.

JC, my pages all have the serial number 891203 stamped on them. Maybe it's the publication date of 3rd of December 1989? Attached some low res scans. As you have claimed, they were drawn by Osvaldo R. Durana.

When I saw the early Mini-500 promo video's, I fell in love with the original prototype machine advertised, instead of the production Mini-500 as we all know it today. Check the video here, especially the scenes starting from from 2:18. Check out Dennis hurling it around the sky.

History of Mini 500 Helicopter - Part2 - YouTube

I have attached some more pictures, seems like it was repainted a couple of times. Check how slick Dennis looks in his younger days, with his white slacks and shoes.

There is even a turbine version in there, the one flown by Mr Cicaré himself.

Thanks Francois, for take the time and clarify the history. I think that the 891203 is the date and S/N of your set, but I'm not sure.

I have pictures on paper of me seated on the CH-4 with 23 years old, (I'm 53 now) ...imagine the shock it was when he presented the little chopper to the public at the local EAA fly in convention in the '83, nobody known about that, I remember passing the weekend near the helicopter.

The turbine engine tested on the CH-6 was built by Gustavo Labala, another mechanical genius here, was even certified and test flown in a C-182. But Cicaré designed and made the PSRU for that engine.
