There is some work to do on.Firstly you have to find some balsa wood ( or another quite soft lime-tree for instace.)
The next step is to make with cutting and sanding the former of the conopy.Of course it has to be fitted to the fuselage.
The next step is to take a sheet of clear plastic ( it can be the clear top of the box for CD/DVD records for example. Also it can be a piece of thick clear foil from different boxes , wrappings etc...there is a lot of them all around.
Then the plastic or foil has to be warmed up in order to make it very flabby. And then it has to be stretched ( wrapped) on the former..
Cuting off and adding the cockpit frame is quite easy at the end.
