Please help me understand: EPA vs. Dual Rate

[B0tt0mline]

Hi,

I am wondering about the difference between EPA and Dual Rate...

Currently I do it this way:

Use EPA for motor if I want to run slower.
Do not use Dual Rate for motor.

Use EPA for steering to decrease/increse steering if needed.
Use Dual Rate for steering to have the same steering on both sides.

Is this approach correct?
Is it also correct not to use Dual Rate for motor?

Thanks!
