This are the pictures of the first flights of our Corsair AU-1.
It has a 3D-printed engine cowl and 3d-printed Engine mount
After we had finished the model plane in early spring, we found that center of gravity was way to far back.
We decided to move engine 40mm forward make a redesign of the cowl and saved 600 grams lead in the front.
It is flying very good now and we are so happy.
The shape of the cowl is not perfect, because of that I want to print a second one with slightly different shape.
...of course the final cowl will get a beautiful painting....
The diameter of the cowl is 260mm the height is 230mm, made of 8 pieces
The plane has a 60cc four stroke Radial engine.
Its wingspan is 215cm, it's weight is 12.5kg.
