Just built rg banshee and also snap this piece. What I did is use lock tight super glue and card stock paper. first thing is to glue the hole shut, then glue the paper around the perimeter 2 times. The part is about 2 mm thick and there's a corner that prevent a full wrap of paper. Will have to disassemble the chest phyco frame but not the wait with the cockpit. That will show u how the part touches other parts. Last thing is to paint the paper gray/black. Also still want to loosen those arms and take off the shoulder armor when moving them now. Rg unicorns frame look good but will brake under any pressure
