Rubik R-22S Június 18 (1/3 scale)

Attiqs · Stagiaire Posteur Inscrit le: 01 Jan 2009 Localisation: Gyor Âge: 47

Hello

I dont know how long is it since that I am watching and learning the retro- plane building methodes here in this website. I was very close to order a Schneder Habicht or an Nemere, but I chose the hardest way. Some weeks ago I stared to design an original Hunarian masterpiece called Rubik R-22S Június 18 (the "laminar 18")

The CAD drawing is based on GÁBOR JEREB book called Hungarian Gliders.

Parameters:
Scale: 1/3
Wingspan: 5333
Fuselage: 2167
Wingroot: 383,5mm HQ/W-2,5/14
Wingtip: 150mm HQ/W-2,5/10
Angle of attack: +2 deg
Wash out: -1 deg

I am not a quick builder so it will take about 1,5 years.

Ciao,

Attila

Nice project Attila. You look very courageous in deciding to start from scratch. You are a master user of CAD tools [clap]

I hope we can meet at the Spitzerberg slope for the 2012 Retroplane meeting. It's quite close to your place (70km)

I'm a proud owner of a Nemere based on Schneider kit. I largely modified it.
See the repair section, you should find my thread.

Bye

Eric

Hi Attila, welcome to the forum Very Happy

Rubik's glider are very original, and few modellers reproduce them. We follow your progress with interest. What cad software did you use?

Hi

Thanks all of you.

To tell the thrues I am an mechanical engineer and I use SOLID EDGE from 8 to 10 hours a day, but despite of the fact it is a big achievement to design a classik glider like R-22.

So I use Solid Edge V20. I think it is quiet good for this purposes. But about 200 - 250 hours of designing time from the 3-wiev drawing to laser cutting is extremely long time. Sometimes I feel that I should have used 2D AutoCAD instead.

Working from scratch is not that hard. Because I can use well know methodes and I can copy them for my purpse. The bigest challenge is the building process itself. I needed some courage to open this topic, because it will not be easy to get near to the "Retroplane quality"

Eric - Your Nemere is an masterpiece. I followed the whole building process from the background in the last years. It would be great to see it in Retroplane meeting. Is it possible to go there as an visitor? I havent seen any information about it.

Bye

Attila

Hi Attila,
Nice project . The fuse of the R22 looks like the one of the Lunak on the front part.It makes me also think about my Sagitta, the sole dutch glider.. It may be aerobatic I suppose. I am going to have a look to Gabor's book. I am sure you'll complete this lovely glider [clap]

Hi all

In the last some month I did some progress on R22-S plan. Still I have a lot to do on it but I hope I can finish it soon. The building process could start at the begining of next year.

Waooouuuhhh , impressive design work ! Will you share your plans in the future?

Yes of course, it will be shared.

Hi

In the last some weeks I finished the R22 plan and ordered the laser cutting. After the boring designing period it is a great feeling to catch the part in my hands.

It is terrible to upload the pictures...

The most "boring" work completed; I wish you 'll enjoy the building step ! Nice work [clap]

Thanks to all of you.

It was the easier part of the job, because CAD engineering is my profession. Unfortunately I dont have so much experienece in scale modelling. R-22S is my secound design.

The first was:

R-22S is a bigger challenge...
