Welcome to the Forums Nezih! Glad to have you with us!
I have built lots of 1/72 planes but as I am now 75 years old with failing eyesight and shaking hands I am changing over to 1/48 as they are a little easier for me. I started building when I was 6 years old so I've been at it for a long time. Whatever I see that I like, I build. My stash will keep me building for the next 250 years (if I don't buy any more). Enjoy.
Jim
