Really a huge gap, which is very surprising for an official model.
But I don't understand one thing : is the connexion between the tail and the body already forcing right after the finshed build with the ball joints and clip connexions ? They are for sure angles which are out of the Lego system. If it does, how could it be validated in the production process ?
Ball joints offer many possibilities, but can they be considered as usable when linked to heavy elements, such as the tail here ? I never used these kind of parts.
And last but not least, was this gap really noticed during the design process ? If yes, what were the solutions you could offer to solve it ? I'm pretty sure that with the variety of tests and TLC expectations you were praising, you could have anticipated it.
And it shouldn't be taken as a sad fact. To me, it means that TLC doesn't care about quality, and sells unfinished, botched products.
The worse is that it's not the only model to suffer from design problems, and we can only hope to encounter as many exceptions as already seen in the past in the future. And I didn't even mentioned the #10221, made by the guy who designed the #10215 and #10240, which are both excellent sets. So where does the responsability in a design process of both TLC and the designer begins or ends ?
Nevertheless, there are still very good, well thought, simple and clever models. I'm only looking forward to seeing these kinds of sets to be still produced :) .
