The plane



History

The Hansa-Brandenburg W-29 was designed by the end of 1917 by Ernst Heinkel as successor of the successfull Hansa-Brandenburg W-12.
The German navy demanded a faster aircraft with larger fire power to resist the Felixstowe flying boats. The W.29 was a two seat monoplane.
The first production series of six aircraft, numbers 2201 - 2206, was ordered in december 1917. Delivery was in spring 1918.
These six aircraft were equipped with a Benz Bz.lIIb. engine rated 185-195 hp. Remarkeable were the six exhausts, pointing upwards at port side of the plane. Also the engine cowling has air intakes.

July 4 the first fight between four W.29s and three Felixstowes occured. Alle Felixstowes were shot down and there were no Germans losses.
The W-29 was armed with two fixed forward firin, sychronized Spandau machine guns plus one movable Parabellum machien gun for the observer.
The fuselage resembled its precendent the hansa-Brandenburg W.12. Also the floats were almost the same. The wings was of a wooden constrution coveren with doped linen.



This will be my next project to start this week .
Just have to print the profiles in a plotter because my regular printer doesnt support it.
Any help on this one will be great.
Hope you like the plane, and also hope everything works fine in the end.
I'll post some photos when i start the work on the plane.

Wow , I'm looking forward to this one Ric ! I do have some info and scale drawings if that will help you out . I can scan them and send it to you .

yes any help would be great.

can anyone tell me the number of the Finescale Modeler where they explain how to paint the lozenge cam with airbrush. that would give me a great help on this one

Have a look at this thread over on the Aerodrome. It may help.

All the best of luck ricardo. Your last scratch was great, I love the beer mats and razor blades approach.

here are the begining of the work, started with the (dont know the name of this but i guess its a) floater...

I will only do one then i'll clone it with some resin to make an exact copy.

still some work to do but its a start
































i've done some planes tinier than this floater

Hey that's awesome Ric , this is going to be one huge aircraft when finished . The one 48 scale is impressive . This will out beat that ! Looking forward on seeing more .

yes i guess it will be huge here is the floater near to 2 1/48 planes

Excellent work, Ricardo. Looking forward to more.

Mark

more work done

floater done







casting silicon mold

copy made, just have to cerrect some imperfections with some putty

Very Cool!

I like it already.

Yuo might find this interesting as a reference.

thank you hugh.

always nice 2 have more references...

gona try to do my best on this one (going to be a very slow built)

Most impressive Riccardo! I really like the ideas you are showing us. The 1/32 scale will give you a monster when she is done. Wow!

well had to remake the 2 floaters.

1 because the putty shrinked and had to build a cover to give it a rounded look on top and the second one because the resin shrinked

waiting the putty to dry to see if anything else to correct before i had the bits on top.






and the real nightmare begins

the wings on this one are made in strange angles so i'm doing my best, i wish i colud have access to all the ribs drawings i only have one and i trying my luck on the others.

started building the inner struct so i can cover it giving it the strange angle look.








doing my best but its a strange bird

Hi Ricardo,
I do not understand what you are doing with the Wing Dihedral. As far as I can tell from all the drawinsg I have at hand, the dihedral is constant from Wing Mounting to Wing Tip.

Cheers,

Hugh

Hi Ric . I'm looking at the scale drawings , same ones that I sent you and Hugh is correct .
It's constant .

I really like the float next to the 48 planes , this will be huge ! Awesome !

well i had started a new one befor i saw your messages, but still i was seeing drawings again and dont know because of the wing shape on the bottom if its so constant or if what we see being constant its the edge of the wing





now its like this but i maybe have to change it again because of what i said before i'll do some drawings and post it here then

one is done

Hi Ricardo,

Although I greatly admire your tenacity and problem solving skills, I think it might be time that someone introduced you to the "Harry Woodman" Solid Core Wing Costruction Method...
I think it would be idealy suited to this aircraft.

Get your self two pices of 1mm (40 thou) Styrene sheet and cut them to the profile of the wing.
Laminate these two pieces while clamping the whole lot over the top of a curved surface in order that when the glue is dry, the Airfoil is maintained on the underside of the assembly.

Now, get some course sand paper and sand the leding and trailing edges to the required profile. You now have a solid core for your wing.

Cut a piece of 5 though styrene sheet twice the width of the wing (there are other matrials that are better for this, but they are very hard to obtain) and cut to the profile of the wing allowing about 3 mm excess anong the trailing edge. Fold this piece along the leading edge (Be careful not to fold so acutely that you crack the styrene). Now score the rib positions on the inside face of what wil and up being the Top of the wing skinning wiht a ball point pen.
This will give you your sagged fabric effect.

Now attach the skin to the underside of the wing core using double sided tape. Apply liquid styrene glue to the trailing edge.

Once this is done and hte glue is dry, sand the excess away to a knife edge and fold the top half of the skinning down over the top of the core and attach once again using double sided.
Apply glue as per the previous step along the trailing egde and again sand/cut away the excess skinning.

All that will remain now is to clean up the wng tips... and since your core and skin are of the same material, this is very easily done.

I must try this my slef one day...

Cheers,

Hugh

I know a link, or some diagrams would help, but I seem to have missplaced my favourites link to the web site that has Harrys book scannned... any one else have it?

trying a new method...just a try ( we learn from our mistakes)

One word.

WOW!

My only worry would be the fragility of the assembly when handling later on in the build.

WOW!

Cheers,

Hugh

Awesome Ric ! The wings are starting to take shape nicely .
What did you use for the covering , looks like tissue paper of some short ?

terry i did use (dont know how its called in english) vegetal paper, its a kind of transparent paper used to copy things and to harden it i used a varnish for metals (its a technic used in simple rc plane built)...it was very strong hugh but i didnt like the finish, because of some badly shaped ribs...so i'm making a new approch a solid wing, my only fear its the weight.

for now without the sanding its 120 grams so i hope i can put it in 70, 60 .


lots of sanding work approching.

the wing made of paper it was not a waste of time because now i know how the wing should look, so off we go.
