CAUDRON AIGLON-Speed 400 sized


Hi all,

As I've to redraw the cowling section of my A1 skyraider, I've started another project, the caudron Aiglon, a primary trainer of the "Aviation Populaire" in the 30's in France.

For this one, I've made the Parts cut by Fellside precision cutting.
It's my first try for such job and I've make few mistake, but nothing that can cancel the job.
Graham from Fellside made a beautiful job, the wood is top quality !!!!!! outsanding in fact.

Specs of the plane :
span is 960mm
lenght 585mm
airfoil clarkY chord at the root 146mm.
powerplant ! : speed 4006V + mpj gearbox.

A shot of a desktop model to show you what she should look like

Now lets the build begin !

Buiding the aiglon


Start with the main assembly of the fuse, then glued the two parts of the flanks, and glued the flank to the main assembly.

prepare tail group.

add a 3*3mm stringer at the top of the formers.

start the work on the tail group, hinge all moving surfaces, sand the trailing edge of elevator and rudder, and round the leading edge.

Wing components test fit


Just to have an idea of the wing structure.

Spars have to be re-work a bit as the slots are not deep engouh, I'll check with Graham that.
Any way I've enlarged them a bit and all ribs match percfectly now.

at this stage no more than 2 hour of work.

I'll appreciate any comments, and any idea for this model.

Fred,

That looks like a seriously pretty little aeroplane!

What are you using for a building board? It's a perfect match for balsa wood!

Tim,

Thanks for the comments, I'm following your work on the seafury too !

The building board is made of "latté", I don't know how to translate it; You're right it doesn't help for the pictures I might consider that for the next pictures.

Fred,
Beautiful subject and great construction. This should look fantastic winging itself through the French skies.

Hi larry,

I hope I'll complete the airframe as soon as possible, and reach the French skies with no trouble ?????
Any way I'll keep posted.

It's remarkable that the Caudron Aiglon, the Klemm L-25, the Ryan STM, the DeHavilland Moth Minor, the Fairchild PT-19, and countless other similar airplanes have a family resemblance. The general lines are very handsome, in a 1930s sort of way.

Quand j'etais plus jeune...(!)


Around '87.... hanging next to 100" glider proto, "Patrice" (one of the ABA kits I used to do)......

Well it was around 50" span (can't remember!), took off and flew sweetly around on an "Olympus" belt-drive 540 with the monster ni-cad buggy pack, standard servos etc. Those were the days of great underpower! Couldn't detail it any more, it wouldn't have got off!! ...but it was nice for about 5 mins

Unless you paid out a lot and knew a lot, electric flight was pretty hard to get right then.

Scaled the outline from your revered Eric Fillon's peanut plan which showed scale outline tail surfaces.

Yours is going to fly tres bon, Fred

Wheel pants


Some work that I've done on teh wheel pants.
On the first I forgot to bevel the rear part of teh pants . I did not make the mistake for the second one !
It's an all wood design, I hope It will be not too weak for landing, as now, it doesn't seems !!!!

Weel pants are designed around a ply main part, where are glueds some layer of balsa. quite simple in fact.

enjoy the pictures.

Wing


After gluing the spars together, test fit all ribs. should be no matter.
Pin the plan on the building board, and the 1.5mm thick trailing edge for the center section.
pin the spar on the plan.
The tail of the ribs are glued to the the trailing edge and the spar.
add a piece of 5mm balsa as false leading edge...
I've start by sheeting with 1.5mm balsa the top of the center pannel.

remove all pins and start the job for the outer pannels teh same way.

Your wing looks good enough to show that nothing like that actually happened to it

...be nice to get loads of balsa that way.... What do you have to eat though?
