Sorry, Dave- I wasn't clear; the gray-anodized stuff is the Sonix brand parts. I don't recall seeing anything there bling-wise except Sonix and MicroHelil.

The MT out of the box is a great bird- there's no reason at all to run down the street for aluminum parts if you're not having a problem and haven't broken anything. I have a metal head and tail on mine because I wanted to run it over 3200 RPM, and you just shouldn't do that with plastic parts. But I flew it the first month I had it with the stock head, and I still have all the original parts preserved so I can go back to it.

BTW, I meant a very small amount of CA .
