Got a question for y'all...

Personally, I think that 185mAh in 1.4 sec IS burst for the most part.

That power calc page is meant to calculate average draw over a much longer run (statistics work better with a larger sample). Using it in that 1.4 sec duration will result in pretty skewed results.

Note that 5275 Watts is the input power, you must mulplicate it by the efficiency of the system to get the real output, and during bursts, efficiency drops, doesn't it ?
Lets say 70% efficiency, that gives how many output HP ?

I think so too (skewed). I just wanted a ballpark number for the peak current in that 1.4 seconds. My conservative guesstimate is 950A like I posted above, even for a milisecond or two.

Have you tried this calculator? This one is more specific to a given set up but will still only average out the power per run.

By the time your finger gets to full throttle, the motor is already building up revs. So my guess is the peak draw on the system is in the first 0.2-0.5 seconds. Data loggers sample every 0.2 sec don't they?

Just realized the data logger thing I said ><
