Lately I have posted a lot of questions but I find the info invaluable before I spend the money.Bare with me a little.

One of the models I've looked into is the century RAVEN 50.
On the helicopter world site it is advertised as ECCPM which I know it means electronically mixed but to be honest
I have never really paid attention too much on these terms as I have taken them for granted so far. I figured I will get into the differences later in the hobby.

But now I am thinking, should I worry about it from now ?

For a beginner, is it important if it's mechanical mixing or electronic.?
Could someone explain to me the actual I guess you would call it difference or importance of them and how it affects me as a beginner for now.?
If I were to get the raven with ECCPM would it make a difference or my life harder in the beginning as I don't yet know that much ?

Thanks.
