"I was very excited to build this set, having finished the 1989 Batmobile in the summer. The start of the build is the same, where a framework is made to build upon. The problem was the second bag created the underside, which has about five larger slabs to stick underneath as part of the framework. They simply did not work, each part keeps popping out or falling off regardless of the amount of pressure used. I carried on building with the hope that subsequent parts will compensate but that just didn't happen. All the way through building the Batwing the underside just kept falling off.
I can only assume this is a defective set I bought as nobody else has mentioned this, which boggles my mind. My only option now is to resort to using glue, which in my mind is very anti-Lego!"
