I think about the construction of the wing and the profile.
This airfoil and wing are too big.
If you have a good idea, write that or upload
the picture or the plan here.
The picture is from the e-book
"Самолёт ЛИ-2" (1946 г.).

This drawing helped me a lot to draw the engine nicalle.

This drawing would have helped me a lot when I drew the fuselage of the plane.
Unfortunately, I just found it now.
I found the drawing here: https://rcopen.com/forum/f131/topic427220/27

Do you have any suggestions for moving the flaps on the center wing?

Here is my e-mail address if you would like to help me with photos and drawings to draw the wing of the model: [email protected]

You can download this book from here: Библиотека

To move the central flap. The one underneath the fuselage you can make a tongue (an straight extension) from the wing flaps (2 sides) and these lower the fuselage flap. Otherwise make a servo inside the fuselage centre section pushing a horn down. Of course all the three flaps have to be synchronized so that they all go down together. There is no short of walkaround photos of the DC-3 on the net so you should not have any problem locating what you really want.

Thanks Reuben.
In what scale do you draw and build your own model?

My first idea is 2-2 servos to move the flaps in the middle part of the wing, since the surface of the flaps are large.

The second idea that I like is the movement of the flaps Strula Snorrason's M1:8 DC-3 model.

I will ask for his opinion and suggestion

I wrote an e-mail to Strula.
I haven't received an answer so far from Strula.
The picture is from the e-book "Самолёт ЛИ-2" (1951 г.).

Nice work Jozsef! It is coming out nice. I use Winghelper and Compufoil to make the wings. What material will you be using to cover the wings and elevator stabs? BTW what google drive are you talking about?

Thanks Reuben!

See post 21: https://drive.google.com/drive/folde...6G?usp=sharing
I plan the fin and the horizontal stabilizer will be covering 2mm balsa and the wing 3mm balsa and 1mm plywood.

My friend cut out a wing profile rib.
When I designed the profile of the model in Solid Edge, I needed a sample to check its construction to see if it was strong enough, as the computer does not return the dimensions.

The structure of the middle part of the wing according to my plan.
Do you have any suggestions about this plan?

- What are the pipe diameters (red tubes)?
- How long are the two tubes inside the center section and how long will these tubes be inside the outer wing?
- Which engines do you plan to use so that you can allocate the firewall position according to the engine. I suppose whoever will be building this aircraft would appreciate to have a firewall position that will fit their engine. My suggestion is to allocate the firewall position with reference to a number of popular engines currently available.

Reuben-Thanks for your advice.

The diameter of the engine cowl of the LI-2 model is Ш282mm.
I choose a Hungarian model engine MOKI/MARK M360 RC,
You can see the parameters here:
https://mokiengine.com/
I think this engine will be strong enough for this model.
We tested this engine.

Jozsef, Definetely a nice engine and a quality engine. However since the engine is a twin inline one do check about your cooling system especially to the rear cylinder as it will have a tendency to get hotter than the front cylinder. Proper ducting should be made to force the incoming air to go through both cylinders. Do check how you intend cooling the rear cylinder as it is very important!
