Default Brushless motor timing

I have been looking into what adjusting the timing does to the motor. This is what it seems to be. When you increase the timing you get higher rpms, less torque, more power drawn from the battery and the motor runs less efficiently thus shortening run times. And I assume the opposite is true for descreasing timing? Less rpms, higher torque, less power drawn from the battery and the motor runs more efficiently thus increasing run times? is this right or do I have bad information? I would think that if you are increasing the power drawn from the battery that you would increase rpms AND torque at the same time? Or no?
Thanks

You're basically right, but the heat increases exponentially too (in the motor and the ESC). Since I'm aware you're doing speed runs, I can simply say for what you're doing, DON'T DO IT!!! lol.

and lower run times dont necessarily mean lower efficiency. you'd have to look at power in vs power out.

So should I just set it for 0 degrees? I think the default setting for it is 15 degrees.

If you are having heat issues, yes.

OK thanks. At least I now know there is one more way to help control the heat issue. I have tried it with all the different timing settings and didn't really notice much if any difference in performance.
