I'm seeing a lot of reference to "HT motors". I searched the meaning and came up with "Happy Time motor". But I can find out if this is a nickname for our fun little hobbie power plants or if it is the name of a particular motor out of the multitudes. And this leads me to another question... All of these China motors look alike (does that make me a racist?). But I hear that they are all but the same. So how do I tell which company makes a particular motor and how do I tell a China from a U.S.A.?
