I have gotten a new kit from Paul with the new plastic parts, and I've got to say they weren't what I'expected, (in a good way of course ). Although I haven't flown with the new parts yet, the weight fells darn right the same, strengh wise, doesn't really matter your motor will snap off first anyways, but feels just as strong as the ply wood parts, and best of all, it looks so much cleaner.

I don't see anything wrong with them. In fact, I rather have the plastic parts now than the ply wood.
