Default RE: What a difference a prop makes!

i know
im fine for the batt 20c (3's) lipo (might be 15 not sure/doesnt matter, im still fine never use 15c)
i usually fly on like 4-5 clicks of the throttle thats how overpowered i am

my motor is rated to 30 amps
but i only have a 25 amp ecs
so in theory i shouldnt be able to fry my motor? (granted, surge current, ect)

35-30-1250 specs

btw i have a bunch of gws 10x4.7e props from a old motor would those give me more torque?
this is getting way to complex.
i just need to know if a 11x4 or 12.25x3.25 will load a engine more or less then a 10x7
