wing

I have a new idea: Why not cut each side of the fuselage above the wing, giving it the form of an airfoil, then add a few ribs under the wing?

See what i mean?

Me too. When nemoskull said, "ive got a 3d printed order on order", I though he meant, "ive got a 3d printer on order".

I was jealous, but knew I couldn't/didn't want to afford one.

actually, its not that expensive, in money. or it dont have to be. but you will pay in something, time, money, but there is some room for exchaning one for the other.

i say no to the flat airfoil. with as low thrust as you are getting, you need all the lift you can get. have you tried heat forming the wing? or even just rolling/crushing it in to an airfoil?

might be with a try.
looks great.

Just rolling camber into the airfoil should work. Wings I rolled camber into years ago still have it. I just used different diameters of pipe rolling on cut pile carpeting.

I always try to roll more camber at the root than the tip and then washout the wingtips.

The Downside to the full skin decal paper is over time it will shrink so be sure to put it on both sides of the wing, because it will flatten the wing out (and bow up the tips) if its only on the top surface.

Thanks Nemoskull and UGN for the advices. You've convinced me to use an airfoil.

I've already removed the wings from the fuselage, They both weigh 3,1g (4mm wallfoam and decals).

I don't think i can heat the wall foam to give it a peculiar shape. It works for depron or polystyrene, maybe.

I have printed the 4 ribs that MeatBomber used for his DC3, if you remember.

I'll cut some thin balsa ribs tomorrow or monday and glue the wing on them.

I'm also thinking about a way to make a slight dihedral with the wings attached to each side of the fuselage.

Dehidr would be good. Keep in mind wing sweep is like dehidral. Too much wil limit your top speed as will an underchambered airfoil. Too fast and the tAil will get Dutch roll.

I haven't done anything more with the wings, but here is some progress on the vertical stabiliser and the rear of the plane.
The piece of 2mm depron will cross the fuselage and will hold the stabiliser, and i will attach the nacelles at each side.

Here is the elevator. Nothing special to say.
I still have to make the wing's ribs and see how i can attach them to the fuselage.

I have 2 solutions:
1) Glue the wings to a central part (that will be inside the fuselage)
2) attach each wings to this central part with magnets.

The second solution allows to remove the wings for storage, but is a little more delicate to realise.
More to come soon i hope.

I've changed my mind. I have glued a light (durobatics) cylinder that will slide into the fuselage.
Also, i have glued 2 pieces of EPP that will support a rectangular piece of depron on which i will install the AR6400 brick.

Sorry, but i do not have a lot of time actually. I must say that i have an other plane to complete.
Here is the nose.

Looks like you put a lot of time into working what must be a hard to manipulate medium!!

Looks great!

It means you have done an excellent job. The thin foam is difficult to work with, and it looks like you must have taken a lot of time to get the model looking so good.

I meant everything as a compliment to your workmanship!

Hi Gene,
I just wanted to understand what you wrote. As i'm French, my english is limited, and sometimes, i 'm not sure about what i understand at reading posts!
Thanks a lot for your compliment. In fact, this foam is very easy to use, and the plan from Fiddler's green are very simple. The difficulty comes from the RC conversion, more than the build by itself.
I work slowly, because i think twice (10 times should i say), before doing something.
This is what slows me down.

Thanks again for your encouragement!
