Hi, has anyone else had these servos going slow.
I have about 15 of these and after a couple of years 4 have started to go slow, first it happens for the first few movements and then they are ok but after a further time of use the problem gets worse. Not experienced this with any Hitechs only the 3050's.
Any known cure?

Have you checked the grease in the gearbox, maybe going hard?
