AW designs and specifies the manufacturing process for their planes. The 1st prototype is sent back to Denver where Rocco flies the hell out of it. Engineering changes (if necessary) are submitted back to the manufacturer in China. The new prototype is sent back to Denver where Rocco flies the hell out of it. (see a pattern). This cycle continues until Rocco is satisfied with the flight characteristics and manufacturing process. Yup, they use Ultracote exclusively.

My only experience is with an older "traditional" ARF (Edge 540T 46/.60) that takes 20 or so hours to assemble. Just finished the assembly and it has a half dozen flights on it (OS91FX). Their new crop are QB's - Quick Builds. Wouldn't know one if it bit me in the arse. Not all is perfect - the covering has flaws - stretch marks (like post pregnancy stretch marks). What amazed me and prompted this thread was the wing covering. The bottom has a white base with 6" Bright Red stripes LE to TE. These were applied over the white. Absolutely fantastic job. The trim and the base are both a glossy smooth surface with no hint of bubbles. And I'm not taking medications!
