Thanks a lot guys.
From the pictures it was difficult for me to imagine how it will look like in the end, so i used the images posted above as background in my CAD software and by carefully matching the camera angles and field of view, i managed to add the computer generated cowl, canopy and landing gear.
The camera lens distorts the proportions quite a bit so in real life the front end is not so large compared to the tail. The sweep in the vertical tail is also an effect of the camera lens perspective, in reality the trailing edge of the rudder is perfectly vertical. The CAD images from the first post in this thread should give a much better impression of the shapes and proportions because the camera lens has a much lower field of view (less perspective distortion).

Unfortunately this is as far as i could get with the Vortex project before moving, so it will take a while before i can get back to it but i will continue to post the rest of the building instructions using CAD images.
