Nemere scale 1/6

Je ne sais pas si ça ressemble au barographe qu'avait fait Eric?
regarde sa construction

Peut etre vous avez raison, quand je regarde le photo encore une fois, c'est bien possible que ce truc blanc est plus en arriere et dans une coffre.

Dear Alessandro,

Thanks for your interest, that encourages me!
The drawing I used for the Nemere scale 1 : 6 is an enlarged drawing scale 1 : 8.
I bought this ( 1: 8 ) drawing (together with a set of ribs and frames, but you can buy that seperately) from AR Flugmodele, costs €29.50 (ex postage) . The drawings were enlarged (by 33%) in a local copy shop. Beware!, these plans are made to cover the plane with 2mm balsa, so had to change a lot of things. (it is in the beginning of this article). On the pictures of making the frames, I use the original outline, but instead of 2mm balsa, (scaled op about 3mm), I put on girders and ply ( 3mm and 0.6), so the outside is about right.
If you want to know more of that, I'am happy to inform you.

Regards, Vincent

Hello Alex,

Yes the model has an detachebel elevator.
On the website of AR flugmodelle are some pictures, so you can get an idea of what you get.
If you plan to build it I can send you some pictures of building mine and if you look at "atelier reparation" you will find the repair of my 1 : 8 Nemere .

Bye,
Vincent.

To begin with, a photo of the assembled model



This was (of course also for fun) and to adjust the ribs at the root of the wing to check with the fuselage if there wasn't a gap. I had to correct a bit on one side.
I went on with the wings, made the tips and the aileron things, to close the gap between wing and aileron, it took some time...





and the result.


I slowly started with the ply covering of the wing, which I had never done First I did a lot of little things and then I made a beginning, the scarfs



Then the bending of the 0.6 mm ply, in the end I did it as you can seen on the pictures, using boiling water, when the water is that hot you feel the ply weakening instantly








I read a lot on the forum about covering the wings with ply, it is quite stressfull! I messed up some panels and came to the following method (it's almost the same as Eric Spore uses on his 1/4 Nemere) for exact location of the first side of gluing I used pins (yes it gives holes....)
Using thick cyano, glide the panel along the pins to its exact spot, after 10 seconds I remove the pins, turn the wing over (plastic under it..)



I bent it open, put glue under the ribs, leading edge and scarf joint and the upper girder, wrap the panel around the ribs and close it, I'am glad its done...




Next is putting the rest the ply on the wings and preparing the canopy mold.

[bocorvin]

I went on with the covering of the wing with ply. First the inner parts. The reinforcements on the rib at the root of the wing is to attach a hook which hold the wing in its place.





I had to incorporate the spoilers.



and check if they still worked (they did!)

Next I bent spruce around the tips and then covered them with ply.



. Now back to the fuselage, especially the wing fairing. I made it first with 0.6 mm veneer, but I didn't like the result, so I took the veneer out and started with ply.


Then there was someting wrong with the fairing on the trailing side of the wing. After a lot of thinking I hope I got it right now.

I had also used a too small radius for the fairing, so I took a bigger one and so I had to take out a strip of ply out of the fuselage Not a pleasant job hacking out ply! I prebent the wet ply

also with a bigger pipe (15mm dia) and let it dry overnight.











.
In the meantime and finished of the master for the canopy and had the canopy vacuumformed from 0.5 mm .


to be continued.

Very nice job. Congratulations for the farings, they look very beautiful.

Thank you! It was the third attempt..... :

Thanks for all the nice comments!
Merci a tous!

Un travail très joli

Merci pour votre commentaire, Miguel!

Je continue en Anglais, first I did some detailing on the wings; in the original Nemere the ailerons were actuated with wires and pully's (see the description of the "Nemere 1936"of Eric Spore on this forum). I made only a non functional pully

and put it in the wing

. Onother 4 small pully's wil come close to the ailerons, but they can't be fitted at this stage.

When the wing is covered with Oratex they are noticeble, surely against the light.
Next I went on with the canopy, put a ply strip over the middle of the frames

added partial frames

The balsa piece on top is temporary to get the girder in the correct shape. I added stringers on both sides and put 2 mm X 2 mm spruce pieces between the frames. Later I glued another ply strip on the bottom to get a rigid structure.









I checked the canopy on the fuselage



To my great relief it all fitted.

I went on with the fuselage, started with the coupling.

For safety I soldered some brass on the inside of the fuselage and glued it too with thin cyano. I made a jig for the push-pull rod of iron wire

and bended a 1 mm steel wire .

after hooking it in I could just straighten it.

Just behind the coupling servo fits the 4 cell reciever pack.

with velcro on the bottom. The receivers fits behind the backrest which is removable

I puzzled a whole day to get the seat together









The seat itself is locked with a not visible magnet.
The on- off switch is just behind the backrest on the left side.

Beautiful work! Congratulations,

Merci Dominique et Pierre pour votre commentaire!

Je continue en Anglais;
I laminated 4 layers of 4mm balsa to make the landing skid, covered it with Oratex and painted it grey. I prepositioned it with two pins with the heads snipped off.



Later I glued two 8 mm X 2 mm spruce battens on top.
After some detailing on the wings they were ready for couloring, covering with Oratex and varnishing. That was difficult, the materials used on the forum aren't sold over here, so I needed onother solution. My wife came up with Bister (dutch name) and obtaineble in art shops, which is brown, water soluable and can also be washed out. I tried a lot of different concentrations on scrap ply and choose to use a rather light colour.


Same with the Oratex colour, the yellowish one or the neutral??? I choose the neutral.

.


I put two layers of cellulose with (porenfuller in German) and one layer boatvarnish.
Put on the ailerons (you can just see the bent end of the steelwire on which it hinges)

glued the actuation segments and push/pull rods.





.
Made a fairing on the verical stabilizer

and a locking mechanism for the tailplane.






Figured out how much lead should go in the nose to get the correct CG.

I use this stuff, pour in about 20mml slow curing epoxy and pour in the "liquid lead"





The pull/ pull wires on the verical tailplane

The tailplane needs still to be sprayed in the colours of the Hungarian flag.. and the ply looks pale, but the colour is the same as the interior in the previous picture!. Made some shots of the plane , couldn't do it outside, raining and stormy and the colour of the floor is a bit distracting.





After the detailig of the canopy I glue the "glass" on .





checked if the spoilers worked OK





a suivre,

Vincent

Bravo Vincent, très belle finition
Je viens d'aller voir le plomb en bille chez eileensemporium.com c'est bien comme matériaux et c'est plus pratique et moins dangereux que d'ouvrir des cartouches de chasse

[DOMINIQUE DIOT]

bravo,tres tres beau

[DELRIEUPierre]

Joli ce Nemere avec sa belle finition

[bocorvin]

Merci Vincent,Dominique et Pierre pour les encouragements!
Quelque chose de "liquid lead" (en Anglais)
I took about 20 ml slow curing epoxy for 300 grams liquid lead. First I put in 10 ml epoxy in the nose with a syringe (keeping the fuselage verically of course) then pouring in the lead, tapping and poking a bit, just like pouring concrete. Then I put the remaining epoxy over it.
It gives a very strong result, this is a picture of my crashed Nemere (1:8 ) the nose is still intact. I tried to fracture it with a chisel and a hammer, but its very strong. Don't use PVA (white glue) it doesn't harden very well and can expand.





You can see the mark of the chisel in the lead/epoxy.

Vincent.
