Servus

Da ich Urlaub habe und und einen netten Kumpel mit Fräse geht es recht schnell voran. Denke Ende nächster Woche fliegt der Paffi! Das Design entsteht auch langsam. Mir schwebt ein knalliges Orange mit Blockstreifen unter den Flächen zur besseren Sichtbarkeit vor. Also quasi wie ein F3B Modell

Hier mal ein paar Bilder:

Bild1 Das aufgeklebte Seitenruder. Wird an den Seiten noch mit Balsaleisten verstärkt und eventuell
verstrebt

Bild 2 SR-Servo oben im Rumpf und eines der 2 HS 645MG auf Höhe. HR mitsamt Spornrad abnehmbar

Bild 3 HR mit aufgeleimten Unterteil des Rumpfes

Bild 4 Doppelruderhorn mit Kugelkopf. Auf die Fläche kommen noch GFK Teile als Abstandhalter für
die Hörner. So haben sie immer den exakt gleichen Abstand.

Bild 5 von meinem Kumpel passend zum vorgegeben Flächenausschnitt gezeichnete und gefräste
Servorahmen. Eingeklebt mit Uhu PorMax. Geniales Zeug, welches tief in das Styro difundiert
und so eine hochfeste Verbindung schafft.

Bild 6 Schleppkupplung. Unter ihr werkelt ein HS 755 MG. Es gibt nichts Schlimmeres in einem
Schleppmodell wie unterdimensionierte Schleppkupplungsservos! (außer zu wenig Power und
senkrechthochreiss-Piloten)

Bild 7 eigens für den Paffi gezeichnete und gefräste Landeklappenscharniere. Gefertigt aus Pertinax.
Bohrung des inneren Horns 4mm, um Messinghülse einzulassen. Äußere Hörner mit 3mm
Bohrung. So bewegt sich das innere Horn aufgrund der Klemmung auf dem MEssing und nicht
das Messing auf der M3 Schraube. So wegen der Haltbarkeit ;-)

How do you mount the elevator into the fuselage? Please show some pictures of your method mounting the elevator ( höhe )

thanx..

Hi Snurre

Sorry for my late answer. I didn´t recognize that you changed your text

I just cutted it off. I left about 2cm from the cutted hole, so it will stabilize the elevator. I use two M5 screws to fix it. So I can take it off an the tail wheel aswell. I took 2 pictures of it.

Sorry for my rusty english Not much left from my english lessons. Hardly speaking english for 2 years and so much is forgotten...

best regards
Jan

Okei,, thank you.. that is okei,, my english is not so good either

I can now see what you mean. I have now finish all the rudders, just have to hinge them together. I shall now begin with the elevator. It seams like å good method to to attach the elevator to the fuselage.

Do you use long screws that goes alle the way trough the elevator inside to the fuselage attached to plywood inside?

And how is your solution using the tailweel. Will it hang free, or will you use a servo to make it turn?..

Thank you for greate helping pictures. Feel free to post more pictures from you buliding prosess

Good morning

I use long screws. M5x100 but I have to shorten it and the tail wheel is fixed by 2 M4 screws. The wheel will be fixed by 2 springs. So it can steer, if I want to turn, but goes back to middle alone. I used it this way at my Trainer 230 before and it worked well. If it doesn´t work the way I hope a small Servo will be attached for the tail wheel

best regards
Jan

Okei I see. I bet it will turn, if not the solution is easy. Well, post a picture of it when its done, and more details if you want And again, thank you.

Hello,

I have now done some building .. Last night, I was awake to 0500 AM building this thing :P

Well, the wings are nearly done, just have to glue the hinges. That will take place when the covering process is done i think.

I am working on the elevator right now, I hope I get it right with the screws ..

some pictures

Hi Snurre (is this your Name or a Nick?)

Looks godd, but I would change the landing flaps. Because with a Distance between Flap and Wings it works muchs better. Look at this picture. That´s the reason why I constructed new hinges expecially for the PAF Trainer. At my 2,3m Version I used buyable Version in plastik but I don´t trust them for such a big plane.

correct Flaps

I hope next weekend will be maiden flight! Color will be Oracover Fluo red-Orange!! On wings donwside I will attache black or dark blue blocks like it is often done at F3B-planes. Because a special plane needs ab special design

best regards
Jan

Hello, thank you. Snurre is just a nick of course

Wow, I have never seen enything like that before. Where can I get these? Baybe I sall change my flaps then.

Maiden flight allready? That is good! I hope my trainer will be finish before the snow says "hello" :P

The color combination sounds nice! Like to see it when its finish! I don`t know what color I shall give my plane yet

I would change it. Look at the real planes with flaps like Pilatus Porter or Wilga. They all have Flaps like I did it as far as I know. There are a lot of shops having flap hinges. But don´t use these ones made of PVC. For a smal plane ok, but for the PAF I would take hinges made of GFK

Best regards
Jan

Okei.. I will se what I can find, and where . Tnx!

Der Rupmf ist bespannt. Die Fluo-Farbe kommt auf den Bildern nicht so ganz rüber, aber glaubt mir: ist so hässlich, dass es schon wieder schön ist

MfG Jan

hehe.. no problem to see this from a loooong distance up in the air =D

what is the status on your plane? I hope I can get the angle for the firewall in right position..

Hi

I hope it will have maiden next weekend. I ordered not enough Oracover and I´m waiting for it. Also it seems I have to change tank, because the wing fixing screws tough it.

best regards
Jan

Okei, I see. Looking farward to see it What about the CG for this plane?

I have one 1,2 liter tank I itend to use. Hope it will be enough. How big weels do you have? I also need a pair of Canisters for my 3w 150.....

Hi
