Bonjour everyone,
Sorry about the language.
My name is Gustavo, I'm writing from south Brasil.
Enjoy a lot the theme old planeurs.
I'm planning to make a Doppelraab.

Hi Gustavo, welcome to the forum Very Happy

Vincent and friends,

Still waiting for some woods, but need a help:
I have 2 prints: one is the plann itself and the other is probably the draws for the laser cut, which shows the "Q" piece in two segments.
Maybe it´s because the laser cut machines can´t cut big pieces?
I will not use laser cut, so is it better to use the Q piece in one single piece, confirm?
Other question is about the need (or not) to build the air brakes (in the wings). They are not in the plann, and I read that Vincent didn´t do it in his Doppel. But if you are doing your model now, will you buid them? If so, where can I find a good scketch?

You can cut the Q part on the middle of the wheel, and glue a plywood inside to boost and have a strong part.
You don't have the drawing of the airbrakes on your plan? [humm]

I'm having trouble to take pictures with max 600x600 pixels. The lowest resolution of my camera is 640x480 pixels, with 95Kb.
Any tips?

Dear Gustavo,

You have to change the weight of the pic with a software ( usualy , they propose a coneversion for Web ) as Microsoft office picture manager. and then upload on the forum.

I started to cut the plywood parts with a blade, but it's too heavy for my elbow. I will borrow a jigsaw tool from a friend of mine. Regret to not use the laser cut... at least for the ply parts.

Vincent, you were right. The air brakes draws are on the plan. Perhaps I was without glasses...
Pat, thanks for the tips with the pictures sizing.
Until now, I have cutted all CTP parts of the fuselage, but 3 of them I will have to repeat cause they broked. Not easy to cut some parts.

A stubbord N1 requires a high skill to shape.

Next will be N2.
