The quality of the 2012 kits is no different from the previous year kits, same factory, same processes, same beautiful results.
Not sure what issues you are referring to? Typically if you receive any defective part from Avant RC, a simple email will get you taken care of, and a new part sent in the mail in a few days.
Parts availability within Europe is equal to that of it is here in the U.S. If worst comes to worst, you can always place your order with CarbonXtreme or A Main Hobbies, both have the ability to ship internationally if your local distributor is out of something.
CarbonXtreme will always have parts in stock incase no other vendors do, making it convenient for any customers needing parts for a rebuild, maintenance, or spares.
If you have any questions, feel free to post, or shoot me a PM.
