JeromeAriola:
That being said, do you think the ESC will arm as it does if I sent 1000 instead of 2000.
Not if it requires 2000 - how could it?
And will it arm so that if i send a 1000 when it is armed the motor wont spin as fast, or will it still be at full throttle?
The value you use for arming does not affect how it behaves afterwards.
Why don't you try these ideas yourself and see what happens?
I don't plan to read an Instructables Article. If you have a specific question about it I will try to help, but please minimise the need to scroll through the Instructables stuff as it is a very tedious website to navigate.
