Remyd,
I know it's been a while since you posted this thread and the follow-ups to it, but i just wanted to take a moment to say thank you for such a well thought out and written-up review. I don't know how I missed this one as it pertains directly to me; I, too, got carried into the hype and bought a set of 10 Orbit 20-18's. The matter got more complicated because, before I had even finished the original build for which these motors were intended, the DP of the project I was building this for (which took place in Puerto Rico) expressed his concern that I should have a compete redundant setup just in the event that something should happen, so as not to delay the entire production due to a repair. Accordingly, (especially because it was part of the production budget and not out-of-pocket) I was instructed to go out and buy aither complete set of these motors for backup's sake. Now, I am the proud owner (shmuck) of nearly 20 of these beauties. I ended up recently purchasing 8 CC Ice 75's just to finally put these to use, so this thread inspires some confidence to that end.
Thqnk you again,
Jonathan
