Slingsby King Kite 1/4

Bonjour a tous,

After that tricky first piece of sheeting, I went on with the top of the fuselage, which was still temporarily attached to the building jig. Scarfing the thin plywood is a time-consuming job, especially if the panels are not straight. I made up a few sanding tools in the hope that I would make fewer mistakes



By the way, the self-adhesive sandpaper “easy-touch” is really great
A little more about this glue technique, I found info on Retroplane and also on SSUK.
After sanding and fitting, apply glue to



and let it dry until it is no longer white. After drying I have repeated the process to get more glue thickness. The fit with the scarfed joints, which are also curved, is critical and I don't know if I can work accurately enough. Another problem was that the horizontal (longitudinal) seam was difficult to straighten, I found it difficult to get each panel exactly in place. I temporarily fixed with it clamps

and glued it with a iron (middle position, 150gr). I decided to make the remaining panels a bit too long and later sand them to the correct length, with another sanding tool





On the same picture the connection horizontal stabiler / fin is done . A picture of the top of the fuselage,




The fuselage is now stiff enough to remove it from the building jig.

Bonjour Vincent,

Superbe ce fuselage, du très beau travail !
Je ferai peut-être un essai avec cette méthode de collage au fer, ça a l'air de bien fonctionner .

Bonne continuation.

Bonjour Sed,

Thanks for your nice comments
About the glueing technique; I find it hard to believe that it is as strong as thick cyano, but hopefully I am wrong!
After the panels are fixed, I put thick cyano on the inside, just to be sure. The glueing itself is much less hectic and that a big plus!

Hi Pat'

Hi Texier,

I used an English tutorial, very informative.

and Pierre Delrieu used it on his Vizzola in 2016;

Hope you have enough info

Hi Texier,

about the glue; I use ordinary PVA, I think that is the cheap white woodglue, indeed vinelique. In the tutorial he says at a certain moment that the heat activates the glue, so don't let it dry completely.


Bonjour a tous,


After the fuselage was detached from the construction setup, I decided to do the rc part first. It's tempting to continue building, but now everything is much more accessible. I had already more or less made the servo tray and the battery box. To be able to get the latter one out easily I made a kind of clip from 2 layers of 0.6 plywood and a short piece of spruce, which you can unlock with one finger

. Next to the switch I placed the shottky diode, made two plugs for both receiver batteries and plugs for the lead to the receiver placed more to the rear of the fuselage.

. I ran this wire between the inner and (not yet in place) outer skin

. Behind the backrest of the pilot I made an “holder” for the receiver, antennas and space for the vario



I had already made the servo tray, I had to glue 2mm extra strips under the rudder servo to make enough vertical space between the actuation cables and rods.
The elevator actuation works with a 1mm steel wire pull / push rod, in a double plastic guide



To be able to mount and dismount the horizontal stabiler, I made the last 70mm of this rod hinged. I bent a very small eye in the 1mm rod, in which the pin of the quicklink fitted tightly. Just bend a slightly too big eye and carefully make it smaller with pliers until it fits exactly.



I can lift that moveble part and then attach the other quicklink to the rudderhorn of the elevator. Then the whole stabiler can be lowered in place and the moveble part of the actuation rod comes “in line” and operates without any slop.
The rudder is operated with two pull / pull cables (20kg strong). They are attached to the rudderhorns of the rudder with self-locking steel wire hooks, so that the rudder can easily be disassembled for transport





The controls are moving nicely, now I can go on sheeting the fuselage

Dear Vincent,

Congratulations for your "every day" new construction solution.
This time the connection with your horizontal stabiliser. Simple and easy!

Congratulation for your idea to hidden, in the cockpit, the electrical wiring between 2 panels. They are defintively glued?

I am waiting for your next building solution.

Best regards.
Harold

Dear Harold,

Glad you liked the idea of the horizontal stabilizer:D .
I had no intention glueing the wire between the in and outside of the nose of the fuselage. I can put the surplus of wire just in that space, always nice when a connector is broken or someting like that.

Best regards,

Vincent

Hello Vincent,
always you have interesting solutions
a question : where do you find this so longers parts ?



I coud do it by myself… but if it's not too expensive…
you have an address ?

Hi Sebastian,

Here is the link to the shop, in the Netherlands,
https://hobbyin.nl/

I try to find these items, put I couldn't find them. Its M2.
Tomorrow I have to order some things, I can ask if he still has them.

Vincent (DB)

[sebastian92]

I don't find it too… perhaps out of sale ?
But I don't think they post to France… and they have no PayPal.

Don't bother with that, I'll make it with threaded rod, or turning it…

Many thanks !

[bocorvin]

I bought these for my FG-2, thats 4 years ago....
Maybe you can silver solder an eyelet to een piece of M2...

I'll ask hem tomorrow.

Ca va très vite à fabriquer, je me les fait, tige filetée de 3mm, quelques coups de marteau sur le bout pour aplanir, et perçage... voir par exemple bas de page www.retroplane.net/bydgoszczanka/page1.htm

[ThomasF]

Ich habe für den gleichen Zweck gekauft.
