Bonjour a tous,
Now I could cover the bottom of the fuselage. I came up with a sanding tool so I could clamp the panels, otherwise my fingers would get cramped
A batten attached to my worktop with a screw clamp , a piece of aluminum angle and two large spring clamps. The sanding went a bit better now
Fuselage and panel with glue , panel in position and secured with a hot iron.
After a few days it starts to become a fuselage
Next is the nose, lots of small panels and that will take some time....

Hi Vincent,
Very great job as usual !
A little question : have you use 0.6mm plywood for the complete fuselage ? And for the nose ?
Good evening.

Hi Sed,
Thanks for yout nice words .
Yes I am using 0.6 mm ply for the fuselage. I will cover the nose cone (pif?) with 0.6 mm veneer (thin, massive wood) so I can sand it without showing the dark glue.

Hallo Vincent,
sehr saubere Arbeit und das mit der Schleifhilfe ist eine gute Idee. Danke . Das werde ich auch ausprobieren.

Hello Vincent,
Your work on the panels is top It is really valuable to spend time on building tools when we see the accurate result !

Bonjour a tous,
The nose of the fuselage is a challenging job. It's important how the fuselage looks, so I hope to do well
I had roughly sanded the nose into shape and I marked the strips on it with a pencil
At the connection to the cockpit cover they follow the round frame shape. Further forward, the strips flatten so that they can be bent towards the tip of the nose. There is no double bending
I came up with the idea to mark the strips with a small router, so you can sand some without sanding away the marking.
Strip by strip, the nose is covered. For these strips I use veneer instead of ply and I glued them with thick cyano
The result
The fuselage is now 1085 gr with 3 servo's and receiver.
Now I am starting the preparations for the wings and the fairing wing/fuselage.

Et après la teinte, on ne verra plus de différence entre le CTP et le bois de placage .
Bonne continuation.

Merci beaucoup Sed ,
You are right, there is not much difference in colour after colouring it. I might make it a bit darker.... This is my Gull
When the glider leaves the factory, its quite light, but after a year or two they become much darker.
On this Petrel there is a big difference in colour. Maybe I can give the nose a darker colour? I think about it

Danke Johannes .
Jetzt die Flugel, ich gehe weiter in English ,
The profile choice I found difficult, the real King Kite had a profile NACA 23021 which looked quite symmetrical. The profile and thickness determine the "looks" of the aircraft and so I ended up with HQ 2.5 with a thickness of 12% decreasing to 10 at the tip. With the flaps (and the ailerons, not prototypical) I can make more camber . With Devwing I drew the wing
Adri was kind enough to mill the ribs and the web plates. The root ribs in 2mm plywood and the rest in 2.5mm medium-hard balsa.
With the program “Calculdelongeron” I calculated the main spar, 24X4mm spruce on top and bottom at the root to 2x10mm at the tip. Should be able to take 10G, not including sheeting. By the way, the wing is completely sheeted with 0.6mm plywood, like the real one. I had previously made a glass / epoxy wing joiner with dihedral that fits in 20x20mm aluminum square profile. Because it has a gull wing, I made a building board with the gull angle and laminated the spars in that angle too.
building the wing
Servo holder, all 4 made in one go
All the web plates glued, left open at the root. So the space between the aluminum square and the main spar can be filled with epoxy /micro balloons.
It's starting to look like a wing!
I'm going to build the other wing now.

Danke Olli, merci Philippe et Christian, pour votre comments gentils
The assembly of the left wing went without delay
Now I could fit both wings on the fuselage. Then I discovered a huge mistake!!! In a kind of having a blind spot I had made the dihedral in the wing equal to the dihedral of the wing connector; ERROR, that had to be half of that , oops.
After some bad moments , I thought better now, than much later in construction.
So I cut out the curvature in the top spar
and with my powerfile I beveled both sides 1 in 10.
I changed the angle in the build board (extensively checked now!) and glued two 1X10mm battens under the topspar to get a stable situation .
. I made suitable pieces of 2x10 mm spruce and glued it between the spar with 24h epoxy with wood dust as filler.
At least now The King Kite looks good, just a few pictures in the garden. .

Bonjour Vincent,
Ouahhh, il est superbe tout monté avec les ailes en mouettes !
Tu travailles vite et bien , et à ce rythme, il sera bientôt prêt à voler !!
Tu as déjà choisi la teinte ?
Bonne continuation.

Bonjour Serge,
Merci pour votre comments!
There is a lot of work to be done!
I am not sure if I choose the light colour as on my Nemere and Gull, or choose for a darker "plus antique "
Time enough to consider. And I am very curiuos what the weight will be. Patience please

Hello Vincent !
always you have solutions
ça va faire un joli modèle ! Les ailes ont l'air d'être très étroites par rapport au volume du fuselage… mais j'imagine que les proportions sont respectées.
Encore bravo et au plaisir de suivre ton avance
Pourvu que ça vole, roule, flotte ! normalement j'ai tout bien fait pour…

Hello Sebastian and thanks for your words!
I was glad finding that solution
The dimensions of the wing are prototypical, in the model; wingspan 395cm, chord at the root 30cm at the tip 12cm.
Maybe its just the photo that is gives the impression.
The ailerons are next and they are rather narrow.

Merci Philippe et Lolo, J'ai bien besoin de vos mots apres le probleme avec le "V" dans les ailes.....
Now that the basic structure of the wings was ready, it was time for the ailerons and flaps. First the ailerons.
I found differences between the ribs in the drawing and the photos
In the drawing, the aileron even seems to consist of two parts, of which nothing can be found in the photo. I therefore decided not to divide the aileron in two parts. Another problem was that the aileron was “enclosed” on both sides. I therefore chose the same hinges as the horizontal stabilizer. The aileron remains removable. With the help of a curved strip you can unlock all hinges at the same time, place the aileron, and then remove
the strips.
After cutting off the aileron from the wing, I realized how long and narrow it was, 115cm long and 4.5cm wide.
The profile choice did not help either, unfortunately. The aileron was therefore only 6-7mm thick. I also became convinced that I had to control the aileron in two places and luckily was able to find place for an extra servo in the wing.
The balsa ribs in the aileron were very thin and fragile. So I replaced the balsa ribs with 2mm solid spruce, took out one, replaced it with spruce, went on to the next, so that I kept the dimensions
I wanted to make a plywood D section for the nose of the aileron. With boiling water I bent U profiles of 0.6 plywood around a 6mm tube and let them dry. I slid the aileron skeleton into this profile and clamped it to a plate with a batten. I had covered both the batten and the board with tape, in order not to get adhesion with glue. I also built in some twisting. I set the plank upright and dripped thin cyano between the rib skeleton and the plywood U profile.
. Now I had a much firmer unit. I further built up the rear frame with 0.6mm plywood and sawed, cut and sanded
the U profile and the TE into shape. Then I added capstrips and the aileron was finished roughly, still needed some sanding.
