Default BL25 Outrunner Motor

I acquired an EFLITE EFLM 7300--BL25 Brushless Outrunner motor (1000KV) and would like recommendations as to Size of Plane to put it in. Weight, Wingspan Etc.
Any and all suggestions would be helpful.
Thanks for your input.
Sincerely - Darryl

Plane type and mass are leading when selecting power (in watt) Darryl. In your case, motor is a given, you use the information in the links below the other way around.
Note that Kv (in rpm/volt) says absolutely nothing, nada, niks, niente, zero about a motor's max.power, max.current, max. torque, max. rpm or efficiency.
Kv does effect current and power drawn hugely though, both are proportional to Kv cubed!!!
Kv only depends on desired (no_load)rpm and battery_voltage, Kv matches the two.Prettig weekend Name:  wink.gif
