This seems like it would either trip a breaker or smoke the 0673.
Are you sure of your numbers?

I was pretty certain until you put it that way.

It doesn't appear to run very hot so far. I can certainly check the current today by measuring the voltage drop across a high wattage, low resistance power resistor in series.
I have seen plenty of shooters on CD this year with the same kind of setup - AM gearbox, FP motor, aiming for about 3 to 5,000 RPMs. If your concern is correct aren't we all in the same boat? If not, any idea where my assumptions have gone wrong?
Thanks!
