Dear Jet - Community,

My name is Jürgen, I'm living in Germany and I would appreciate you posting
a report about my first construction in this forums. I posted it in several
German forums and got positive feedback. Hopefully it will be the same here.

Besides...the Topic is called MiG, because its Made in Germany ;)

Some Background information:

A few weeks ago, on Jetpower trade fair, I met a friend of my father and we
had a little conversatin about Jets. He told me about searching a model that
is more broad in the waistline, so that he has more space to work in inside
the aircraft. Moreover it should have a big hatch, because that would make it
easier to put in the turbine-engine and maintain it.

Speed is less important than the ability to make neat manoeuvers. The Jet
should keep stability in the air and better not pull into the wrong side while it
is doing a vertical side slip. It also would be nice, if the jet is able to take off
and land on a short taxiway.....and will fit into an Volswagen Golf after landing ;)

After a few days I started designing an aircraft that combines all his wishes
and a few more.

I designed a mid-wing aeroplane, that is completely made out of glass fiber
reinforced plastic, with a hatch that is nearly 3ft long. Furthermore I took big
aerobaticairfoils with airbrakes. All moving elevators and exchangeable fins
are also part of my idea. Finally the plane shall have an electric landing gear,
but ut should have the opportunity to fit in a mechanical one, too.

And thats what it looks like:

http://www.rc-network.de/forum/attac...p;d=1257865156

After getting all measures and thanks to my experiance in work with glass
fibre I am now able to say which weight the plane will have. Therefor I made this measure index.

The first aerodynamic measurements I made with FLZ Vortex. Secondly I built
a small model and sent it to a friend of my father, so that he can pu it into
the windtunnel. after a few days he wrote me his suggestion for improvements
and I directly improved my model.

And here the measures:

Overall length: 2150 mm (84,64 inch)
Wing span: 1750 mm (68,89 inch)
elevator span: 812 mm (31,96 inch)
aerofoil: 90,33 dm²
High from ground: 736 mm (28,97 inch)
weight with P80 and Kerosin 9825 g
area loading 108,77 g/dm²
V Max. about 97 m/s
V while landing with air brake 14,63m/s

I hope you will like it, =)
with best regards Jürgen

keep it coming would be interested to see it fly

You have my attention. Looks very interesting.

Very nice work!! Will be watching with great interest.

Hi! Jurgen; where the air intakes would be? Underside ?

Interesting plane.

ENT

Привет Юра!;)

We will attentively observe of your project!
Very interestingly!!![:-]

Aleх.

@E.N.T,
Hi! You can see the air intakes on the pic, NACA

How about a thrustpipe and the legs for the Orka? http://www.rcuniverse.com/forum/js/f...wink_smile.gif

Greetings Jurgen

thats cool looking.. kinda has the old bugatti racer lines to it.

Jury,

Pipes it is necessary? There are no problems, will make!
landing gear are necessary? There are no problems, will help your project!

Hello

Your project is really interesting espcially your tests in the wind tunnel....
Keep us informed !!

Thanks
Jean Philippe :D

Nice model....
Maybe a bigger airplane could make the diference....

sry, I did not get what you mean! could you explain your statement, pls?

Sorry i should explain.

Your project bigger and whhaaaooo.....

I think the market needs bigger planes 2.0-2.5 meters.

Bigger plane better fly...

Congratulations for your project. I know that you willl have sucess with this beauty plane.

Very nice, and interesting look to it. It look like a mix of the F-9 Cougar, F-18 Hornet, and the L39's vertical tail.
Not to mention the stealthy nose of the F-35 JSF. Best of luck with the project and hope to see it flies here soon.

@JM-PORTUGAL:

Thank you! I'm glad you like my plane, but it will have a length of 2.0 - 2.5 metres..... rather 2.15 metres http://www.rcuniverse.com/forum/js/f...wink_smile.gif

@yf222000:

Honestly it is a hybrid of this:

....and a fantasy of mine.http://www.rcuniverse.com/forum/js/f...ular_smile.gif

Next step:
I found a paperwork about building an I-16 Rata....
http://www.rc-network.de/forum/attac...p;d=1258144640

Wooden planks encase the body in an angle of 45°. I used an 2,2mm styrofoam-fibre glass sandwitch to
do the same with my model. It was done fast an after fixing it with fast-drying epoxy it will be ready in a few hours.
Unfortunately I can not use these technique for the whole body, so i will take balsa 3mm balsa straps to plank the
nose, tomorrow.
http://www.rc-network.de/forum/attac...p;d=1258144640

From your blueprints, seems like it is very roomy in the main fuse compartment. Gotta love that,
especially when dealing with installing the engine and other supporting equipment. I lost counts
as to how many cuts i got on my hands from installing the engine in my Rafale, although it has some room in it.
Over all, it is an eye catching jet. All the best to you sir.

@yf222000:
There will be more than enough room http://www.rcuniverse.com/forum/js/f...wink_smile.gif
I wonder how you managed to cut your handshttp://www.rcuniverse.com/forum/js/f...eeth_smile.gif

The next target is to finish the body.
As I said I used 3mm balsa straps for the nose
http://www.rc-network.de/forum/attac...p;d=1258233955
http://www.rc-network.de/forum/attac...p;d=1258233955

After the glue dried I used glass fiber to seal the upside.

http://www.rc-network.de/forum/attac...p;d=1258316319

while it was drying I had time to concentrate on constructing the elevators

Hi Jurgen.

I would love to be the first one to fly this plane.... I would like to make the first order!

I have one Booster 80 ready for it!!

@ JM-Portugal
I am very glad about your order! How about having one below your christmas tree http://www.rcuniverse.com/forum/js/f...wink_smile.gif
I promise you will be the very first one!

Back 2 business:
Body was spackled and grinded

It was from twisting and turning my hands inside the hatch bay trying to get the engine's tubing and cables to run underneath the bypass. :)
The opening for the hatch has some really sharp edges. I had sanded it down a bit, but still pretty sharp. I lost sense of getting cuts when
i was so focus on getting things to where i wanted them to be. Only later after sitting down, only then i realized how many cuts i had received
on the top of the hands, and or forearm from reaching inside sometime. :)

This model making thing is becoming more and more dangerous http://www.rcuniverse.com/forum/js/f...eeth_smile.gif

Today I cut out the templates for the wings and prepared the styrofoam.
http://www.rc-network.de/forum/attac...p;d=1258574886

Good evening,

today I spent some time to cut out the sideparts

http://www.rc-network.de/forum/attac...p;d=1258664084
http://www.rc-network.de/forum/attac...p;d=1258664084

After that I filled the passages and grinded them, untill they had the right profile

http://www.rc-network.de/forum/attac...p;d=1258664084

greetings Jürgen

Hey Folks =)

Last weekend I spent a little bit of time again to work on my plane.

At first I put 2 layers of 160g/m² fiber glass and 1 layer of 80g/m² fiber glass on the side parts.
The 80g/m² layer was put dry on the side parts to absorb the superfluous resin. So grinding
will be easier later.
http://www.rc-network.de/forum/attac...p;d=1258818851

Now the elevators:
Of course it was possible to make them out of styrofoam and encase them with fiber glass, but then it would have been
necessary to make them two-parts and they had to be adjusted, too. So I used ribs and a 0,8 mm balsa-fiber glass
sandwitch to construct my elevators. The balsa-fiber glass sandwitch was made in vakuum and after 3 hours of drying
I cut it into the right form. After that I glued the Sandwitch with the glass side on the ribs and put sandbags on it, so that
tha sandwitch could embrace the ribs. Then I put it into the oven and heated it to 60°C (140°F). To plank the other side
without distortion I cut out styrofoam profiles. After that I removed the pedestal of the ribs, put the elevators in the profiles
and planked the bottom.

http://www.rc-network.de/forum/attac...p;d=1258818851

After they dryed I put 2 layers of 80g/m² fiber glass on them and fit the hull for the pipe into the rear.

http://www.rc-network.de/forum/attac...p;d=1258818873

Finally I built the side parts for the elevators

Really cool! Kinda resembles the Russian Yak-130
