While I have seen some of the centering issues with the 605, I have a more substatial problem with mine. My 605 seems to oscillate for a second after abrupt steering inputs. Not just a single correction or for a fraction of a second, but a large number of vibrations. Almost like a radio 'glitch' can look like, only this seems to be an issue with the servo. I run an M8 radio with Airtronics recievers, and I have tried replacing the reciever, crystals, and even tried a different transmitter with no changes. Suprisingly, the condition is much less severe when I attempt to use my ancient Airtronics CS2P transmitter. If I replace the 605 with another servo, the problem dissappears and the new servo operates smoothly without any vibrations..

Any ideas on the source of the problem??
