Fokker FG-2 - Congrès 2017 Vauville

[bocorvin]

Bonjour Christian,

Merci pour les comments!
J'ai essayer de faire une tete comme Anthony Fokker et pour le passagier la tete est completement phantasie.

I tried to make a real different head (even his nose is crocked ) so every resemblence with Vincent is purely coincidence!

Salut Frédéric,

Merci beaucoup! Je fais de mon mieux et je suis retiré !
Et le Willy Farner donne moi beaucoup d'inspiration!!

Amicalement

[Philippe26]

Et oui,
Nous sommes quelques uns à nous être retirés ici après notre retraite.
Retraités retirés, retirés grâce à la retraite ?
Tant que nous pourrons poncer des bouts de bois, les coller, les peindre ou les vernir, et ensuite les faire voler...
Vivent les retraités qui se sont retirés sur Retroplane...
Et aux autres , je vous souhaite d'y arriver à votre tour.
Amicalement,
Philippe retiré lui aussi dans les landes Provençales....

Amicalement,
Vincent

[Clifton]

Bonjour a tous,

I had asked my sister, Hans, to make the clothing for the pilot and passenger and she had already promised to do that.
First I had to make the boots. I used "porienfuller" to make the balsa smooth and thin ply as soles.

, painted it with acrylics umber and burnt sienna



made it a bit darker


In between Hans had made the clothes



(the hands are already fixed, but it was very dark weather to take photo's)

I went outside when there was a bit of sun:

I was very glad with her effort!

My sister Hans put in a lot of detail!

With fitting the hands I had to cut off the arms bit by bit

and before gluing checking if it all fits

yes, I still have to change his left arm

When fitting in the plane I noticed they looked a bit "scared" and I guessed it was the position of the head(s), so I changed that.

and put 3mm carbon for strength

I couldn't find goggles, so I made them myself, the more 'basic' type, used in that period. First I had problems with cutting the glass and making the rims, till I realised I had a lathe! So from waterpipe I cut off two rims and sharpened another piece as a pons? to hammer out the glass and the leather (yes from the same purse )







and glued a 2mm elastic band to it. Also I discovered that the chairs were not correct, so I made new ones with a back of two layers of ply, used the same seat cushion.



Now I had to fit them in! First the passenger

and yes, the belts are very wide and the closure is much higher placed than nowadays

then the pilot

Its crowded in the cockpit!




Adri was so kind to make the decals, on the photo's only the number "4" is visible and we took some artistic freedom to add the "Fokker" logo as had almost all his planes on the vertical tailplane.






The Fokker is now as good as finished. It turned out to weigh 4450 grams, a bit heavier than I expected! I had to test something. I was uncertain if the rigging had weak points, so I did a static test, first with 6 kilo's and then with 15 kilo's ( its an 80 AH car battery on top of the wing)

I was very glad it passed this test without a hitch.
Now we have to wait for better weather to make decent photo's outside and make the first flights.

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

to be continued,

Vincent

Hi Vincent,

ich kann mich nur wiederholen:
Genial was Du da gebaut hast

LG Johannes

[Philippe26]

Hi,
You write its an 80 AH car battery on top of the wing)....
I have not understand yet that it was an electric glidder.......

O.K. it is not serious....
Anyway, your passenger don't seems happy to fly......
And to finish with my stupid jokes, it is a wonderfull work !!!
Wunderbar ! (i am not sure of my german....)
Congratulations !
Philippe

[VincentB]

Bravo Vincent, superbe tes pilotes on ne peut qu'encourager le "home made" ça leur donne une âme qu'aucun pilote du commerce ne peut avoir.

[bocorvin]

Danke Johannes,

Es war schon um zu bauen, viel gelernt Thanks for your comments!

Hi Philippe,
Yes the passanger didn't look happy, it was intentinally, I can imagine that, he was the first passenger in a glider ever!!
Nice jokes ! thanks for your comments!

Vincent

[bocorvin]

Merci Vincent! Your stories about making heads helped me a lot!
Also helpful for me was youtube tuto (sorry English spoken )

[bocorvin]

Merci Dominique et Clifton pour les comments!

I'am very lucky to have a sister who can make that!

Amicalement,

[Mad Doc]

Aaabsolut sprachlos bin ich!!
Was für schöne Details! Ich wär so gerne dabei wenn die Fokker fliegt...

Liebe Grüße,

Christian

[Fotor]

Today Vincent and I assembled the FG-2 to make photos.
We also made some hand tosses. Exciting! But the result was not yet optimal.

Vincent will share the whole story tomorrow, but here some teaser photos.

[patte de loup]

Wonderfull work.

[Mad Doc]

Wow!!! Mehr Bilder!!!
Grüße,
Christian

[bocorvin]

Thanks Pat, Christian and Raymond!

We had an eventful day, yesterday! After a long period of dull weather we had sun, so it was an excellent opportunity to do a fotoshoot. Raymond knew a nice location, so we started;


The building up takes a lot of time, I am thinking of improving that...






Wires all over the place....

And securing pins..

All those ribs...

Last wing slides on its place..













It had the nice transparancy where I was looking for





It was difficult to hold it!

Finally completed!

Because it was nice weather we decided to make some hand tosses.
Some problems became apparent.
First its difficult to get an hold on the fuselage?? so it was difficult to toss.
This is a link to a video of the bulding up and first tosses.
https://www.youtube.com/watch?v=nnVJrVO_WWs
As you can see, it needed some improvement!
The rigging appeared to be to weak, a lot of wire was not good clamped


The strain on the wires is pretty high with the kind of "landings" I made .
I also have some doubts about the wing warping, I am lokking to improve that.
Ther was also some damage at the wooden parts, a bit on the root of the wing and the skid.


I'll make the next changes; replace the rigging with heavier wire (90 kg) and improve the clamping, also securing the clevices and testing if it is strong enough.
Looking if it is possible to enhance the warping. I have some doubts about the control off the rolling, horizontal tailplane gives ample control!
Repair the skid and wing. When that is OK the FG can be towed, it is good that this weak points of the plane are discovered with little damage.

Thanks Raymond for the mental support!

To be continued,
Vincent

[VincentB]

Hooo, Vincent, you are crazy to do hand launch with this model at the field not enough speed to have good reactions, use a bungee or go to the slope or towing, please stop hand launch before destroy it

[bocorvin]

Hi Vincent,

Yes, I am going to tow!! it and yes I am a bit crazy . Luckily the model appeared to be quite strong
We don't have something like a slope but you are right, no hand launches. (with the Nemere it went OK, that's why we tried it)

Thanks Vincent, I'll listen to you

Vincent

[sebastian92]

Yes, marvelous !
keep cool, you have time to secure all

[michel]

le lancer à la main comme ça sans vitesse quel risque dommage!
Tu as de la chance Vincent il n'y ait pas trop de bobos.

Michel

[Sed]

Bonsoir Vincent.
Ton Fokker est vraiment splendide et je suis soulagé de voir qu'il n'a pas subi de dégâts trop importants !
Je m'excuse par avance si je "pollue" un peu ton post, mais cette petite mésaventure m'inquiète quelque peu car à dire vrai, je pensais procéder un peu de la même façon le moment venu pour faire voler le Tenax... Et au vu des différentes réactions des pilotes expérimentés du forum, cela ne semble pas du tout raisonnable ! Pourtant, je ne suis vraiment pas très chaud pour le lancer directement dans la pente sans avoir pu effectuer auparavant quelques réglages. Alors je me permets de m'adresser à eux à travers ton post pour savoir comment ils procèdent pour le tout premier vol...
Bons futurs tests .

[bocorvin]

Thanks a lot Michel, Sebastian and Sed for all your comments and advices!

I am very glad there is little damage and in this way I learned about the weak spots of this plane! Fokker himself made also a lot of changes on this plane!
Sadly I could not do as Fokker on this picture



I knew the risks of hand launches, but there are also risks with towing or bungee.
I learned a lot of it, I'll make some changes in the wing warping and rigging and I have got the confidence now to tow it!

Vincent.

[Johannes]

Nicht kaputt machen, Vincent
Sie ist viel zu schade!
Ich mache solche Erstversuche immer mit Flitschengummi:
Erst nur mal rutschen lassen, dann immer etwas mehr vom Boden weg
steigen steigen lassen, so kann man sich drauf einstellen ohne zu viel Schaden zu verursachen (meist )

Gruß und viel Erfolg beim erneuten Erstflug
Johannes
