Fokker FG-2 - Congrès 2017 Vauville

[Mad Doc]

Just Beautiful! Maybe it´s good you found out where the weak parts are before you go to Retroplane 2017... Would have been even more annoying.

Surely it will look marvelous in the sky!

Greetings,
Christian

I just remember a Airco D.H.2 I had built. It was a really beautiful thing, unfortunately on the maiden flifght I had to find out that my wires were not tight enough, too... They got into the Propeller and the Propeller ripped out the controll wires from thre rudder... THAT was sad....

Hello Johannes, Christian, Phillippe,

Sorry for your plane Christian its sad to see it happening.

Thanks all for your caring remarks!! I think the bungee thing is a very good option to make first flight attempts, it good to dose. Slopes and towing is a bit more frightening for me
Luckily there is not much damage and easy to repair. I never built a biplane with functional rigging, so I had a lot to learn. Specially the shockloads are so much higher with rigging because the whole thing is so stiff. I will replace the rigging and I already changed the servo arm of the wing warping to give greater travel, its now 7.5 degrees up and 7.5 degrees down.
Don't worry, it will be OK, at least I know its quite robust

Hallo Vincent,
kannst Du mal schreiben wieviel Spannweite und Gewicht Dein Modell hat?

Gruß Johannes

[bocorvin]

Hallo Johannes,

Das sind die daten;

Some facts of the model;
span 2m 22cm
lenght 1m 45cm
wing surface 132 dm2
weight 4450 gr
wingload 33.7 gr/dm2

Im anfang hatte Ich gedacht dass die Spannweite des Originals 12 meter war, 2.40m als Model. Spater habe Ich dan entdeckt dass das Original eine Spannweite von 11.20 hatte, im Model 2.22m.

Gruss, Vincent.

[Johannes]

Danke Vincent

Und jetzt schnell wieder alles reparieren

Bonjour a tous,

The first thing I had to tackle was the rigging. I ordered wire for 90 kg, but it was to thick, not good for the looks . The insufficient clamping in the bushes with the 40 kg wire was the problem, the wire just slipped out. I think this was a mistake of mine. I am familiar with sailing and on sailing rigging the clamping is 100% free of slipping, so I just clamped the bushes. Now I learned to make an extra loop in the wire to get it slip free.


I replaced all the rigging, except for the rudder controls, because the loads are so much less.
Next was a new skid and I decided, (because its an vulnarable and essential part) to make a spare one.

laminating with thin CA, the thermos bottle is to keep the water for bending nice hot.

coloured with bister and merisier from "Liberon"

On top, bottom and sides I put glass roving with epoxy.

Connected with 3 M2 bolts to the fuselage




Finally I repaired the wing






So the Fokker is ready to fly again, we are going to tow it, hopefully coming weekend, the forecast is good and Rob is getting his Piper ready.

Congratulations !

Dear Vincent,

Nice repair. This plane is so beautiful.

Concerning first flights I am working as follow:
On the slope, with some nice Wind, I am running with the glider in my hands and I am "feeling" the movement. Up or down? It give you already good informations.

See you next time.
Regards.
Harold

Hello Phillipe and Harold,

Thanks a lot for your encouraging comments.
A slope is certainly a good place for a first flight. Regretfully, the only slope in our region has a very nasty landing terrain, very, very small, with barbed wire around it and a lots of turbulence, with a modern glider with brakes is still tricky.
So we are going to tow it, nice flat field and I have adapted some controls, less elevator and more wing warping, so I hope for the best.

I have had the honour of witnessing the first flights of the Fokker yesterday. It was beautiful!

I't up to Vincent to tell his story, but here are the pictures and movie:

The plane had a lot of attention.





Some adjustments




Ready for takeoff



















The sunlight throught the ribs is beautiful.













Vincent was a happy man!




Celebration with some eclair-like cakes.




And a special car-sticker was made.




Movie of the first flying day.

I have not been able to fully enjoy the view of this magnificent plane, because I've been looking at it only through my various cameras, but the resulting photos and video make up a lot for that.

[bocorvin]

Hello Raymond,

Thanks very much for making this wunderful film and the also the pictures
I am very glad the FG-2 flew, still some work on it, we think th c.g. is too for in front ( it flew with about 10 degrees elevator up)
But it flew! and the anemometer really turns

Bravo Vincent, superbe vol, belle vidéo
Ce n'est pas évident votre piste, atterrissage de l'autre côté du canal, faut pas aller dans l'eau
On a hâte de le voir évoluer à hauteur des yeux cet été à Vauville surtout ne l'abîme pas avant Retroplane!

Vincent, les photos, la vidéo ,un régal

[bocorvin]

Merci a tous pour les comments!

To start; the FG-2 had a lot of things unknown to me, so I am very glad it worked out well!!

About the canal; this flight terrain is an former military airfield, which is now demolished. Sometimes ditches and small humps appear, but we are very glad to have a place to fly in this crowded piece of the world!!
Yesterday we had all things together; the tow plane, the photographer and good weather, only the wind came from an unusual direction. This stretch of tarmac was the only place for take off, and the other side of the canal was grass and the only place to land without damage.
Surely I try not to damage it before Vauville!!
Now I can do the finishing touches!

Vincent

[Clifton]

Absolutely marvelous Congratulations. So beautiful is it ! And the video very nice too !

[Sed]

Vraiment superbe Vincent (le modèle, la construction, le vol, les images,...) !
Je suis très heureux pour toi de cette réussite après les petits soucis des premiers essais .
Mais si je comprends bien, tu es passé directement du lancer-main au remorquage !?
Je te souhaite plein de beaux vols à Vauville .

[bocorvin]

Merci Phillippe et Sed pour les comments!

Yes I went directly from handlaunch to towing. I have very little experience with "le sandow", thats why.

On the pictures is the nice transfer from Adri and Rob, this is how it looks;



I don't think a lot of people recognise it
