This was made from different bits of Kinder suprise toys. The ammo belts are from cut down tank tracks, the window, a corner from a musik cassete box, "pilot" from and old Airfix jet.
Not the best scratch build, but my first attempt

I would of been well happy if that was an actual toy in them when i was a kid...
instead of the rubbish that was usually in them.

Practice makes perfect.

Looks like the arms swivel too! Everything is in good balance. Nice work. Keep working on these...I want to see more.
