Thank you gents, for your comments.
Now the second part of the update.
The fuselage is almost glued together.
The ballast is glued inside and the office is finished.
I still have to consider if attach the glazing and the cockpit roof to the nose area first or attach the nose section first.
AMT did a terrible choice making the glazing and the roof separated. Still confused.
Meanwhile I did some work on the wheels.
The -300 nose wheels are too small, so I decided to use the KC wheels, but their rims and hub are inadequate.
Not bad at all, but just different.
So I scraped away the hubs and the rims.
I placed a round plate between the wheels halves,
built a new hub and glued in the middle.
Unfortunately the tyres have no thread, so I scribed it with a "hi tech" tool.
Some Tamiya white primer and painting.
Also the 8 main tyres received the same thread treatment. Believe me: I have other 6 tyres in a box.
Tha's all.
Have a nice week.
Eugenio
