Fuse. The two orange tubes are antennas. -

Cramped electronics compartment. I enlarged the original OSG plans considerably, and yet I was har pressed to get all the stuff in -

Battery compartment. Those shiny plates behind the motor are ballast (140g of it) -

Bulk-head is still depron. The fuse walls are 3mm depron sheeted with 1mm balsa using UHU POR -

I got some fancy-pants push rods with a snap-on mechanism. DIdn't like it, cut it of and went for a trusty old connectors. -

Silicon hinge. They are just GREAT! The horiz stab hinge turned out a bit too thick, so I put cuts to it (5-6mm at a time) until it felt right. -

Wing in all its' glory! The outer panels are still not glued to the main (middle) panel. -

No "waves" no more! :) -

Almost perfect! :) -

Test-run with balsa. Shortened the burned parts of the EPS, replaced them with 3mm depron, and sanded Depron down as far as I could. At the thinnest position, the balsa shimmers through. -

This is NOT the TE of a S6063, but I hope it won't make much difference. -

The test segment from below. Gotta get rid of this headache before I'm ready to smell some more UHU Por! :D

As you can see, I moved the fin a bit towards the nose. That way I only had to cut into the rudder, as shown on the plans. -

This is still just a "dry fit", so I am still able to pull the whole construction out -

Here you can see how I moved that fin towards the nose of the plane - by cutting a slit into the horizontal stabilizer -

I also had to cut some foam out from tail section to accomodate for the fin, which now reaches "into" the fuse. -

Templates for my hand-held hot-wire foam cutter. Made out of 2.5mm balsa, and carefully sanded down to be as close to each other as possible. -

My 5cm Blue Foam sheet was somewhat too short, so I had to cut out a part and extend it a bit. It seems UHU Por holds like hell on this material! -

Here it is - the monoblock! I'm not quite sure whether it was really necassary to cut out such a big part in the middle, I might put some foam back, to make it more crash resistant -

Another view of the monobloc.

Child labour in Austria. ;) -

EPS block for re-enforcing the fuselage, with balsa sticked on it to act as a tunnel for the push rods -
Views: 212
The re-enforcement / push rod holder finished. If you look closely, you'll see the openings where the push rods will go. Also laminated, to make it more resistant. -

Motor mount - another view. Glued with CA, then with hot glue. Attached to EPS with UHU Por and additionally secured with carbon rods. -

The pushrod holding block you saw above, also acting as a holder for the RX. Servos located between this block and the monoblock. -

ESC in the lower compartement, for better cooling. The lipo in the final configuration sticks all the way in, to achieve the correct CG. -

A view into the fuse. The top cover is placed on two sideways depron strips (you can see them above the wing holder) and only attached by packing tape. I guess having that part removeable will help eventual repairs in this area.
