I have two different types of motors that smoke when at full throttle for 30-45 seconds. Based on my calculations, these motors are drawing about 70% amperage to their specified maximum. Is this typically a product of poor manufacturing or is this typical of brushless motors?

Not joking. What would cause smoking? You mention "decent setup". Can you be more specific? I have a properly rated discharge lipo, an ESC with enough amperage rating for the draw, and a motor.

winding errors in motors can do that, but most commonly it's too high load.
The smoke is the enamel insulation of the copper wires and/or epoxy used. - in any case - too much heat.
What motors are you using (brand, model, KV)? , what propellers (size/pitch) ? and voltage (cellcount) ?

Unless you are joking, it's very bad.
Brushless have much better efficiency than brushed motors, in decent setup, you'll not feel any heat after a flight.

does both types smoke ?
