...and the Vivak has been put on the frame with canopy glue, and after cutting the edge, hinges, a nice fit!
Now the window must be made and the rails.

The front cover needed also a small magnet to hold the wire hook in place when the canopy is closed.
Now the fuselage can be closed up completely. I needed the two holes at the rear of the seat to get to the locking system while installing the canopy.
When the window will be in I can open and close the canopy easy enough.

The front corners of the cover have been filled with thickened 5 min epoxy to be able to grind a bit off.
This to allow the installing and taking it off again without the need to take top cowl off (a few screws on there...)

Noël,
It looks as if you draw your carburettor air in through a flexible pipe through the main firewall to the forward fuselage where you have your air filter. Thus you draw engine air from inside the fuselage.
Is that done in order to reduce air intake noise & therefore overall noise.
I know someone who was thinking of doing that with his DLE powered Titan tug.

Hi Peter,
indeed I always take the air from the inside of the fuselage!
I used the flexible tube and made a small filter, not to fine wire mess but to keep dangerous particles out of the carburetor and engine.
What is more, this helps a great deal to keep the noise level down indeed!
The other benefit I have doing this is that the high needle screw needs to be opened less than normal.
This means fuel saving and flying with Aspen this helps to reduce the cost.
The Tartan, it has been test run but not properly yet, I will know soon what that will do.
When a carburetor is popping out from the cowl or just sits in the open air, a lot of fuel is blown away. I never have found proof that I lose fuel in the fuselage...
The trumpet helps here also a lot!
That is why I put ( some ) work in the carburetor arrangement like I have shown, it pays off!

The window is made and screwed onto the canopy now.
The one I bought from Graupner was a bit small so, milling and cutting had to be done to shape a few strips of 5 mm SQ Polycarbonate plastic.
The window has springs on to keep it steady in place. These are made from sheet Silver solder that is hard enough for this job.
1 mm rivets hold the springs in place. Work fine! I used a clear round plastic rod to make a handle to open or close the window.
