It doesn't matter, switch two of the wires. Believe me, I have been building and selling quads for years.
They are also called engines by definition, being a machine that converts energy into motion. I'm sure all, including you, had no question what the OP meant by use of the word.
Actually, as we teach students in physics, engine convert heat into mechanical energy (as in internal combustion or steam engine) and motors convert electrical energy to mechanical. But, yes, we did all know towhich part on his phantom he was referring
Yes, no doubt we had the word engine in common parlance before the first electric motor came into existence. I understand the distinction, and you got my point. I shouldn't have bothered commenting earlier however I find it frustrating when people correct others unnecessarily- especially when they are wrong. I'm pretty sure it was the same person who tried to tell me that a falling object will hit the ground at 32fps no matter what height it falls from.
