Now I've had this MOC on my desk since my birthday in November, and I still haven't posted it here... Figured that had to change!
From the back -
The gear mechanism holds, because the main gear is connected to one of those 1x3 pins with an axle hole, so it's got 2 pin connection's worth of friction.
From the side
I thought I'd show off the changes I made to Tahu has well, so here they are together.
While Tahu has ''gear armor'' on his shoulders, Kopaka has it on his knees, kind of as a nod to the piston armor placement in 2015.
and that's all she wrote!
