Michael, Carbon plane does not crash ever.
Carbon takes all the blows without injury.
Such aircraft best for learning.

Hello metrorcflying,

you can order mylar from Woodhouse, UK. http://www.freeflightsupplies.co.uk/

Glad to hear it!

Thanks for pointing me to Post #6 for the joint details. When I looked closer at the one close-up photo, I could see the wrapping thread.

I'm surprised that this works for you with CA. My attempts of repairing Vapor landing gear where it meets the fuselage tube and for repairing the motor/gearbox mounts has not worked out well for me with CA. I think the CA somehow stiffens the thread so much that it breaks on impact. Actually, my first attempts were using carbon TOW. Later I tried cotton sewing thread with similar disappointing results. Perhaps I used the wrong CA or something. I eventually settled on using 30 minute epoxy over sewing thread. That's strong, and more foregiving. Probably heavier, too.

Anyway, thanks for sharing all you have on this technique, your plane design, and the terrific videos.

My real interest is in something small and extremely light and slow-flying, like a Vapor, but with ailerons. Not sure how I'll proceed on that. I don't really care about fuselage side area for knife edge flight.

Jim,

Here's a link to a thread about an aileron vapor made by Gordon Johnson.

Go to European competition is very desirable.

I think you forgot to add Lithuania my friend We book date for our third open F3A championship for 2011 03 05-06, you same as Evgenij are invited. Soon we will launch competition website with all information, this year event will be registered at FAI calendar.

It would be very nice to see your new plane.

My friend Anatoly Morozov made carbon aircraft "MORANA.
Weight: 40 grams.
Wingspan 650 mm.

Donatas, thank you for inviting me to your competition in Lithuania.
For me it is very interesting.

Alexey,

That is the most amazing indoor plane I have ever seen! After seeing the video I just have to build one.

Do you have a top and side view drawing that you would like to share? Also, I see that you have used an aluminum tube (?) "back bone" in the fuse.

I can see that you have a lot of time invested in the assembly of the airframe and would like to know some of the assembly tricks or problems you had to invent or solve to build the airframe.

What was the bare airframe weight shown in the picture?

Thanks,

George

Hi George .
Central tube of 6 mm, wall thickness 0.1 mm made of carbon-coated metallized Mylar 3 microns.
Weight of the aircraft without the Mylar 31 grams, with Mylar and painting 36 grams.
I'll be glad if my technology will help many people.

Alexey,

Thanks for getting back so fast.

Here are few more questions:

Did you build the top and bottom parts of the fuse seperately and then fasten to the CF tube "back bone"?

Same question for the wing, two seperate halves and then attached to the CF tube?

Any close up pictures of the motor mount and tail section?


Thanks again,

George

Look post 682 http://forum.rcdesign.ru/f86/thread129147-18.html

Hi Alexey,

What size carbon fibre rods do you use?

Andy

Andy .
I use a 1-mm and 0.6 mm

Alexey,

More Questions:

What was your source for the "backbone" CF tube? What did it weigh?

What CF weigh and number of layers did you layup the prop with? Any pictures?

Thanks,

George

Carbon tube made of a single layer of fabric 0,1 mm.
Is it handmade
Weight 2 grams.
