Hi, I just bought this Continuous Rotation servo and it works like a charm! However, I’m having a bit of difficulty connecting a 3-inch wheel to the thing, and when I try to remove the screw from the servo horn, the innards and servo horn itself move with a slight whirring sound. It doesn’t want to stay steady enough for me to remove the screw.
Is there an alternate way I should be approaching this? Do I have to pull it apart from the back and knock the screw out from the inside?
Hold the round servo horn from rotating and rotate the screw CCW. The screw should back out with little effort. You can connect the tire to the servo like this.
