Thanks Joe  
Yep, and it's pretty light, so, I'm more and more confident for the first flight..
We'll see anyway ! But fingers crossed !

Hi there,
Here we go again, this time with the fixed rudders. First, cut the parts. The plywood is used for the aluminium tubes brackets (not sure of that word..) :

Then, nothing really difficult. Just a puzzle to assemble :



Just to have a look at the beast, and have an idea of what the finalize project is going to look like, I've setup the elevator/rudder on the booms. we can see a close up of the rudder / aluminium tube junction. Easy and simple ! :



And a general view :



Well, so far, I'm happy, and the machine is looking really good. I even start to like it !
The glider seems to be light so far, and that's good as not a lot is left to be done (sheeting, and all the moving things (rudder, elevator , ailerons..).
Almost there !

Fred

Hey Alan,

Little by little !
I'm only working 1 or 2 hours a day on the machine. But you can do a lot in 1 hour already !
And Thanks to the Irish television who shows only rubbish stuff, I spend more time in my garage !  :wink:  :wink:

Hello there,
Back to the building, and this time with the elevator section.
Not a lot of pieces for the fixed part :

And we glue everything together ! The central rib id made in 3mm plywood and will received a mini servo for the elevator :


Then, the stab TE is closed with 1.5mm balsa, and the LE made as usual with 10mm balsa. A balsa block is cut for the stab ends, and will later receive the rudders. Et voila :


Tonight, rudder or elevator.. We'll see !  :rolleyes:

Bet your glad you built that cnc machine!

Me ? Noooooooo  :lol:
And I'm still using 1 or 2 hand tools ! Ok, that hurt a lot my delicate fingers, but that remind me the good old time !  :lol:

Hi there,
After a Saturday at the slope, a bit of work has been done sunday on the Opel, starting with the fuselage. The pieces :



Not a lot ! So, that goes really quickly to assemble :


After that, not a lot of work need to be done on it. Plywood sheeting, and space for the pilot, batteries and receiver.. Yep, no servos on the fuselage, they are all in the wings and tail !
First look at the fuselage with the wings :

Well, looks like the picture... Always a good sign !
Back to the wings for a while, and it's time to glue the LE (10mm balsa) and the TE (1.5mm plywood) :


Then, we do the same on the 2 external wing panels, and we can do a final setup and have a look back on the beast :



Well.. Not bad at all ! And the more I look at it, the more I think that can have a decent flight !

This week, it's time to work on the tail (elevator and rudders) section ! More ribs !

Well, not that much really.. Only 2 spars glued yesterday, and the tubes for the wings keys... That's all.
But thanks to the CNC anyway, as without the machine, I'll still drilling holes on the ribs ! (around 200 for the wings...)

Not a lot of work done yesterday, but things are still moving !




Plan for this week end : TE and LE for the wings and I start building the fuselage or the tail section, we'll see.

Hey Alan,
Yep, that's the plan  
Only for meetings, for the scale touch !
But I hope that this glider is going to ...glide correctly without the rockets (and going in flames after that !  :lol: )

Well, we'll see... That's going to be interresting anyway !

Secret.. Well, let's say not known yet !    

So, here we go with the external wing panels :
So, at least 1 and a half panel is done ! I had a shortage of pine for the spars ! used 10 mtrs, and I need 2 mtrs more...

One panel :


Junction central wing / external panel :


Tonight, I'll try to finish the remaining wing panel, and the central wing section.
