How is the tau'nar in terms of difficulty to build? Were there any surprising mold bubbling/weakness issues or anything, or was it pretty straightforward?
It's a pretty straight forward build compared to other titan models from forge world. The most difficult/nerve wracking bit is getting the 4 parts for each leg glued into position to ensure the stance you want and ensure the pelvis is level. Also some pinning done to strengthen the various leg joints.
It obviously has the usual FW fun and games.
