Thank you Doug.
The "hood" is glued together as well as the fins of the radiator and the radiator. Joints between airframe and hood were repainted.
Adjustment is very rough. However this type of circular hood is common on the planes of WW2 ( isn't it?). This one does not pose so much problems( on the plane of WW2).
Eduard will seriously have to think about question next time....
The hood is a bit brought forward towards right and the fins of the radiator are not therefore wholly vertical.
The gate is correctly put in the ring. However the stem under the radiator is not in the centre and I should have put the hood even more towards right......
So many splendid pieces of plastic which gather so badly, it is so sad...
