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 !

Comme d'habitude, de beaux modèles et une belle construction. Bravo !

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.

Superbe Vincent !
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.
