Here are some pix of the construction, wings fit very well, was a easy job.
Javelin wings with just one small part added , and a revell Stuka fuselage .
But the gun channel at the nose was very difficult to build , more time than the rest of the plane!
It is a rocket tube , the gun is some landing gear from nowhere … very cheap russian fighter kit , mig 31 , fleamarket crap .
Engines are made from some 1:35 bombs and rockets and sheet .
