I need to work a bit more in the central part. Must add the screws to fix the wing to the fuselaje. The uper servo in the picture will controll the ailerons, and the other servo will controll flaps.

The wing is now 131g. And everything is 374g without the electronics, not as heavy as i thougth.

Looks great!
Where are the servos for the flaps and ailerons going to be?

Take a look to this. Both servos are goin to be on the bottom of the central wing section, so they will be hidden inside de fuselaje once the wing is attached.

Wow! How does that work? What is connecting the servos to the flaps and ailerons?

Look the small blue tubes on the wing, I'm using a steel guitar string passed through these to control the ailerons and flaps. Take a look at this https://www.rcgroups.com/forums/showthread.php?1741454-1-servo-2-ailerons
This other image i found on internet (it is not mine) is better to understand what i did.

Are those just 9 gram servos?

Yes!!! it was a bit complicate to achive because i couldn;t find long tubes with the correct inner diameter so i had to use those:
what a pain.... to place those toguether.... one by one 
But this way i can control aileron and flaps only using 2 servos, instead using 4 servos. (i am really short of that)

Yes, regular cheap 9g servos. It would be better to use 9g metal gear servos, but i use what i have
.

I used a single 9g servo to controll both ailerons in my Biloute and it works pretty well. No issues reported and was same 1200mm wingspan.

Also, what thickness of guitar string? What note?

I am definitely going to build this airplane! It's too cool!

I am using a "E" (the thickest
). can u see it in the picture???
This is not the best way to do this because the coiled guitar strings improves friction against the tube, forcing the servo to work harder. There are several comercial items for this

But again.... i use what i can find here

I can't wait neither
. I'm stuck with the installation of the lights. Until I finish the circuit I can't finish covering the fuselage, and therefore... no maiden flight.

What's the trouble with the lights?
I put lights in my bushwhacker, so maybe I can help!
