Default Motor sizing

How do I determine the electric motor size needed for a specific airplane? I can't figure out the motors are rated.

100 watts per pound for easy flying. More watts more power.

Would help if you told us what plane you had in mind?

The size given by manufacturers in many cases is at least what's needed (some definitely describe it that way). If you wanna go a bit faster / better climbing, use more but take care not to use too much. In example +25% power will push it recognizable in many cases. Good luck.
