Thanks for the help, Dave!
Yes, I do mean a potentiometer. Couldn't remember what it was called when I posted. I only say that it is for adjusting servo position because that is what the included directions say it is for. Worst instructions & customer service I have ever experienced (Hobby King) - and I've been around long enough to have lots of substandard service! I guess I could buy a servo just for testing purposes, but maybe I should just buy something more foolproof, as I only intend to turn motor on & off & have 1 speed setting in between. No remote control wanted.
