EG Wing Gundam.
All I did was paint the shading, camera eye, head sensor, shield nose and distinctive sphere on the chest with a Gundam marker.
I can't help but be impressed by how easy it was to build and the form at such an affordable price.
And as for the transformation into bird mode... what, there's been no official announcement?
So, so what happens is that there's a slit on the back and a protrusion on the shield that fits into the slit, and there's a hole in the shield for the buster rifle to fit into, and when you fold the thighs the thrusters are exposed and the shoulder parts can be smoothly fitted along the arms.
