Great series of pictures Juanfe. They do it justice and bring her to life.
I altered my power system from two fans, one 80A controller on three cells to two 80A controllers on four cells. It has gone from a flying pudding to a spritely aircraft.
Cheers,
Terry.

Its made with EPP in 3mm and 5mm. Fiberglassed witn 20/48 and 70 grs/m.
Inside with carbon fiber, some balsa, and wood in 3mm.
1,95 aprox x1,95 . Weight (without painting 3700grs) ready to fly.
2x70mm EDF from HK with 2 45amps ESCs, turnigy regulator, 5x 3kg servos, 1x1,6kgs servo for bomb bay...1 4S LIPO 4500mah.

some preliminaries...

Thanks Terry Mitchel for inspired me with his great skills with depron and his Canberra too.
Thanks Tito Johnston, a great person! a great designer...
A lot of people help me to carry on this project. Thanks everyone!

Thanks
Very nice build and it flew wonderfully. I hope mine comes out as well as yours.

Thanks Rosie and Rich!

A little more...
Building the front and rear parts of ribs in the central section

Making the formers where inlets and outlets tube, anular shape.
The front spar (wood), has 2 anular reinforcments in wood, same shape.To increase the strenght in this weak area. Weak because of the minimal material left after sanding and shaping these circles.


Begin with otuside parts of the central section...wings!
See in the pictures...the poliestirene (foam, depron...dont know the exact name of the material y used because here, in Argentina, the seller don't know exactly the name...but its expanded polyestirene)

After that i'll put 2 roads, square shape, 5mx5m fiber carbon, in the fuselage direction, joining two wood spars and the rest of fuselage...pics!

Starting to get in shape!wow..no room in my department!!!

i'll make the wings couple. 2 spars in each wing (carbon fiber circular shape)..and in the central section a bigger carbon fiber circular, just big enough to let the wing spar to enter...) The central section is fiberglassed with epoxi and thin layer of fiber glass (120 grs)
The wing fix will be done with a screw and a new spar made of wood. See th pic.

I am extremely impressed by you guys that build the big jets, also envious because I dont have a field big enough to fly one that size nor the room to "hangar" it, but looking at your work makes me smile, very cool!

Thanks Joe!
litle jets have their goodies too!

More progress...
start cuting circles for the fuselage..(the holes are for pass servos cables or other cables)

i did the bomb bay (artuculated) and inspired in the real Canberra
Just foam and balsa.


making the nose retract gear suport...wood, 3mm plywood..


Working in ailerons...no push roads to see. Everything (pushroads) will go inside.

ready for fiberglassing the beauty...
fiberglass with epoxi and 80grs, 40 grs and 20grs fiber glass cloth.
The 80grs for the intrados, the under side of the plane...lighter cloth for the tail.
