Grab a beer and some crisps, you have some reading to do. Don't try to take it all in in one go.

Take it to the club, let them have a look at it, join the club.
Troubleshooting is much easier to do live, less questions because they can see a lot rightaway.

What plane/make/size/type/mass?

What happens when you connect servo instead of ESC on throttle channel? Does it move with the stick you expect it to, full throw?

What is the battery type/voltage/#cells/capacity?
Charged correctly, what charger?
Same question for controller, there should be some voltage indication.
Propsize and -diameter?
(Small changes, massive effects: current drawn is proportional to pitch, voltage², Kv³, and diameter⁴.)

Current and voltage-sag when running, rpm?

Other possible causes and solutions:
Motor stuttering? Won't run?
