Im putting together a E-flite Carbon Z cub SS 2m and would like to know if any one has upgraded the motor to a E-flite Power 60 400KV or something else. My question is will stock controller hold up , Choice of battery size and prop. Thanks Dan

Welcome Dan
I can't give you a direect answer, but keep in mind that ...
Current drawn is proportional to Kv cubed (and proportional to pitch¹, voltage squared , diameter⁴ ).

It is a good practice to have some headroom built in. About derating motors, controllers, batteries, electronics in general:

• Motorcurrent is proportional to voltage squared, and proportional to Kv cubed.
  A 10% change in battery voltage will give a 20% change in current, a 10% change in Kv will give a 30% increase. Not quite, because battery voltage will sag more due to higher current, but you'll get the idea.
• extra current with one or two cells added, simple table

People upgrade all the time with that motor. But you will need to go get a bigger esc.

Anyone else seeing/getting huge smiley's in my replies above, instead of normal size?

Edit:
Smiley problem solved.

Thanks for the info. I was hoping that some one already did it. Dan

What I’ve read so far is to upgrade to the eflite power 60 470kv, not the 400. Also upgrade to the castle creation talon 90.

I did the power 60 upgrade in my first Carbon Cub, and will be putting the Motor/ESC combo in my new orange Cub...it could use the extra boost in power...
