I get that the numbers like 2206 (fictional number , not from anywhere) is the size of the can or the size of the stator or shaft?
There is not set standard. Some company measure the can, others measure the stator. You need to look at the amperage, weight and wattage.
Secondly, the K/V rating is rpms per volt, and as I think I understand this, the lower the kv the more torque but slower the motor bigger prop is needed. which is better for a slow flyer. The higher the kv, the faster the motor but less torque so a smaller prop is needed but the motor will be better suited for a faster application.
Sorta but not really. The lower Kv will not a bigger battery (more cells) to turn a higher RPM. You can have a 700 kv and 1400 kv motors turn the same rpm with a 6 cell and 3 cell battery. Your prop and battery size will determine the Kv you need.
So my question is do I look for an esc that will match the max constain amp draw or the max burst draw of the motor or do I calculate what power I am using with what prop I will be applying to the airplane I choose to fly.
Go 20% above the MAX Amp your motor will pull. It (ESC) will run cooler if its not being taxed out all the time.
