Building the wings...
Like the fuselage, the first step will be to create a "kit".
The 5 first ribs are cut into 3mm plywood. All the others ribs are in 2mm balsa.
Not all the ribs are here. Around 4 are missing.
So, you have your kit, let's start ! Absolutely nothing new in the building.. No, no new technique, materials and so on. Just wood, only wood ! Even the air-breaks !
The spares are in Pin (12x4) and the ribs are simply glued following the plan. Dead easy !
Don't glue the ribs in the centre of the wing where the air-break box is going !
Oh by the way, the lower spar is not flat ! From the start of the aileron to the wing tip, the lower spar is elevated for about 12mm (cannot remember...). This give the wing a aero dynamical dihedral . The upper wing is flat, but the lower wing (if you look at the wing from the LE) have dihedral. The building is much more easier like that as you don't have to calculate the angle for the wing key !
Nothing really difficult here.
The next step, and may be the most challenging (but easy, finally...) is to create the air-breaks.
First step is to create the "box" that will support the mechanism.
The ribs are made using 2mm balsa, and the box, in Plywood (2mm). You can glue that to the wing, you will add the front and rear ribs later on.
The air-breaks are entirely made using 2mm plywood, some screws (M2) and bolt and a bit of balsa. Easy to make. But first, and to be sure, a model is made of the air breaks, using bits and pieces of wood :
Ok, it's working ! Note that they are articulated with carbon tubes. The tubes will be held on each side of the "box". But pictures will tell you more about that.
Then, it's time to put everything in the box and manually check that everything is going smoothly. Now, it's time to do some sheeting, using 1.5mm balsa (and not 1mm as I did... ok, that's light, but too fragile ! )
And you put the LE at the end !. Made with 10mm balsa.
Et voila !
