Question about matching esc to motor
I i have a question concerning matching an esc to a motor. do you match as closely as possible the same amperage's, or do you get an esc that is slightly stronger?
I am getting a monster 32:
Max Burst Current:
I was thinking of getting the Volcano 40 amp: continuous 40, burst 55
would i be better off with their suggestion that they add to the shopping cart? volcano 60amp:continuous 60, burst 80

Theres is two ways of doing it.
#1 you go based on what the actual PROP and motor will draw
#2 you go based on motor max.
The second is kinda better as this will allow you to use it in different application is it could handle more.
Example of #1 - motor max amps 50 but the prop and motor will only pull 20A so you could get away with using a 25-30A esc.
Example of #2 - motor max is 50A and you get a 60A or higher esc regardless of the amp draw the current setup uses.
SO now you have a 60A that you could use in a bigger setup or a more amp demanding setup...
This is my esc to motor selection for Dummies..

I always err on the side of caution and go one size higher than the peak amps... I like 10-20% safety margin. I would recommend the 60A, and don't forget the programming card!
The ExceedRC Volcano series are re-branded Hobbywing Pentium's. Also sold as Turnigy Plush from HK. They are pretty decent ESC's.
Note: The 40A and higher (excluding the opto versions) have 3A switchmode BEC's. There are my favorite for larger planes as I can safely run 4 servo's off them.

So using the 3w/g rule, no more than 630W.
3S = 56.7A
4S = 42.6A
I would suggest even those numbers may be optimistic.
If you really want to see some grossly overinflated specs... look at what XYH publishes for these motors:
7S lipo & ~1100W!
BTW, I have no experience with this motor. Others may have some better first hand experience.
