alternativley make some small (~2cm) cuts in the hinge so that there's less resistance for the servo

These are very light and quick, but fragile. Housing is about 1/2 the thickness of an HS-55, so gears are *tiny* and strip easily. Torque is adequate for shockflyers etc. Resolution is not as good as HS-55. However, after the winter storage, I found they had become quite jittery probably due to potentiometer corrosion. Reports of problems with the 3.6g ones are common. Out of 6 of these I had 1 defective, it was the pin on the plug.

I bought three of these for my shockflyer. Out of the three one had centering issues, the other two are working well. They are powerfull and fast for their size but quality control seems to be a bit lacking.
