As a very wise technician told me as he reached out from inside a computer:
"Remember two thirds of all problems are operator error."
And this can happen at any point along the way from the guy measuring the original for the model, the guy translating those numbers and complex shapes into a mold, and so on all the way down to the guy at the workbench trying the assemble the kit he just got from his local hobby shop. It's a long and complex process where so many things can go wrong.
But remember if you couldn't do something but somehow someone else made it work with all other things being equal? It was you. Own your mistake and learn from it.
Wouldn't it be nice for Dragon to own their mistake and admit they messed up with Black Label and somehow retool and fix the abortions they've done? Imagine a new Special Edition Smart Kit of the M103 comes out with an all new re-tooled hull and turret.
How many times did Dragon re-do their Nashorn and Sherman VC? There was at least one complete new re-tool in there. But they tried again and eventually got it right. Or at least reasonably close.
But someone, somewhere isn't learning the lesson this time around.
But I learned my lesson. I won't buy one and if I do, I'll bite my tongue and build it out of the box just to have it and not complain. (like how I've done two Academy Sheridan kits. I built them as is and I just don't compare them to any pictures or plans of the real thing)
