July 15, 2013Application(s): Steering in 1/10 scale Tamiya F104 F1 car
Comments: Replaced an Airtronics 94102 that was in the car when I bought it. Difference is like night and day. There was considerable lag with the Airtronics, but with the Spektrum lock-to-lock steering is nearly 1:1 with the controller. Keeps in lock-step with any steering input between the extremes perfectly.
I'm just newly getting back into the hobby, so this is my first digital servo. There is a small amount of clicking/whatever at rest (not high-pitch whine - more like a click/tick sound). I'm led to believe this is "normal", though it could be my ESC (Novak Edge), as it's a budget ESC. I don't see any issues with brown outs, though. All of this is just FYI. I don't "feel" any of this while I am driving it. Also, there is *no* observable flutter (e.g.: putting it up on a stand doesn't have the wheels twitching/oscillating). In short, other than it being annoying, I don't see any impact.
Since I've seen info on the Internet about all Spektrum digital servos having 25T splines, I also wanted to mention that this servo is actually a 23T spline. Because of this, I need to spend some time playing with the servo saver to get it aligned. I am cheating at the moment and just using trim (about 5 ticks on a Spektrum DX3S).
