Pat may have some data to back this up, as I am just assuming based on the 1509 specs.

When you guys say "~400-450 watts continuous", what does that mean?

a) You can run them with enough load so that they are putting out 400-450 watts for "X" minutes [fill in "X"]

b) You can run them with enough load so that they are putting out 400-450 watts until you dump the typical 5000-6000 mAHr 2S LiPo battery that fits in a 1/10th scale RC car at which point the motor is almost toasted

c) If you had a 6 ounce miniature nuclear reactor that fit in an RC car and put out 8.4V at 65 amps and would run 2 years between refueling, you could run it at the max load of the reactor (figuring 85% efficiency on the motor), stopping only to lubricate the bearings if/when needed, until the reactor needed refueling 2 years from the date you started the test (anyone remember the IB Infineon PDF sheet (joke) from a few years ago?)

d) [you fill in this alternative]

I'm just trying to get a feel for how long "continuous" is supposed to mean and under what conditions of temperature and cooling/heat sinking.

Also, how long can it run at the "surge" rating?
