This is G-Core plane from Gundam RX-78. I would like to use as less parts as possible to build this plane with "limit" transforming feature. I used around 90 parts to build it.
The main challenge is coming form the "double hinge" transforming structure at the middle part. Unfortunately the plane's head and middle wing still need removed after transformed to core mode.
BTW, If have good response, next phase will build a Gundam RX-78 upper body to fit this in!
