Wingspan: 23"
Lenght: 21,1"

On my Site http://www.balsamodels.eu I will be publish
Pictures from Progression (in 3D Rhinoceros).

But Day have only 24 H

Been watching the CAD work with interest.

I'm thinking that 23" span is going to make the engine nacelles pretty darn small. Plus the added weight of the four nacelles with that small amount of wing area will tend to make a small version come out with a heavier wing loading. What about more like 30 inch wingspan? Not a whole lot larger but the wing area goes up by a lot and making the nacelles should be a little easier to do neatly.

With PROPS on each motor? ....

If I were to try doing a four motor RC airliner it would likely be more like a 5 or 6 foot span model or even larger. I want something that big in real life to still be fairly large as a model. Just doesn't seem right otherwise for me.

Wow! This is interesting to see how a model is made with 3D CAD drafting. Your final model will be very nice, Ronny. I am looking forward to seeing pictures of the building too.

I agree. It's really neat. Especially the "in cabin" view looking down the row at the formers where in a full size aircraft we'd be looking at passenger seats....

Ronny, I think that if the nose block ahead of W1 is going to be the spinner for the prop I would make W1 with some down and right thrust built in so you don't need to add too much to the nose block that plugs into W1

Hello.

My Idea is Trust down and right according to section A in Picture.
You think, that according section B it is better?

On second thought it really does not matter. Either is fine and gives you the thrust offset you want.

There is a saying in English "six of one, half a dozen of the other". And it applies here

Oh wait! If you were to make the nose as you show partly as a spinner so the prop hub is hidden and just the blades stick out THEN it would be better if the first former was angled. But if you will just use a regular prop with no spinner on the nose then either option is fine.

A spinner nose would sure look nice in the air. The prop hub is always clear and easy to see but when turning the blades just a short way out from the hub become just about invisible. So if you were to hide the hub and first part of the blades in a spinner..... Hmmmm?
