I would slightly touch my steering controller and the servo would rapidly jitter moving about a millimeter both ways, but when I'm on track its smooth as butter. My friend commented that it is a trait digital servos have. Any others experienced these results?
I have a pm-3401 low profile servo that does the exact same thing, in regards to not operating when the receiver/radio are turned on. When they are switched off then back on it will work. I was curious if it was an actual issue or just some normal thing. It is an excellent servo, works great and once it operates I never have any issues! Just sometimes the initial turn on, no operate until you turn off and back on! Curious as to the cause of this as well, hoping it never goes any further and becomes an issue to get it to operate!
