Yes, I flew 8 packs on my Trex. They fly very nice. I had a bit of a problem at first when setting up, one of the servos was buzzing very bad and getting warm. So I opened it up to see if the gears were binding, while at it I took the opportunity to take some pictures, it was the gears that had a slight bind to the case, so I torqued the screws lightly to relieve it and it stopped most of the buzz and chat..

Now, I can often hear the servo seeking center, sounds a lot like the DS95's from MKS, buzzing and chattering. But when in the air all you hear is the heli. It holds the heli with authority even in windy and high g 3D maneuvers. On the bench now and at first setup, they exhibited minimal slop when powered up. But only time will tell how well they hold up.

Side note, the gears are slightly larger than 450 size gears.

Look pretty typical. Did you lube them or were they that loaded up when you opened the case?
