Alturn 750MG Servo. Noisy & stiff.

[V6Jim]

I have a new Alturn 750MG servo which I think may be faulty. It works OK, but it sounds laboured and feels slower than it should be. The worst thing thought is that it's poor at self centering. This then involves me in constantly trimming the steering for straight ahead.

The steering mechanism itself is totally free, so it's the servo that's possibly dodgy. It was cheap (£18 from Motorsport) but it does feel odd.

Anybody else out there with experience of these servos?
