Hello to you, too, Kendalboatsman.
Sarcasm? No, not at all. I was merely trying to ascertain the connection between your title of this thread and a possible answer for you.
But it transpires that what you really want to know is the current rating of a suitable motor to match the output rating of your ESC.
Entitling the thread 'Hitec ESC' led me to think the question was of one concerning a Hitec speed controller. As you already have the specifications of said ESC, it might have been more prudent to ask if anyone could suggest a suitable motor, rather than just guessing on the '545 being a possible contender.
I have taken the liberty of searching the Web on your behalf. Google does indeed return many pages, all of which are relevent to your question. And even though I've got big t**s and a stupid face, it wasn't too difficult to find.
Like most everyone else, you probably find it easier to assume sarcasm, rather than assistance.
Sincerest regards.
