help with getting correct components

[jongam0]

not sure where to put this but,

i have had no luck from asking people or finding info (what is needed) on how to figure out how much power is needed to power a heli. 250,450,500,600,700E, all need a certain amount of power but, what is the minimum? what is overpower? how do you know how to pick the motor kV,batts.,headspeed for the heli? is there some place to find this info?

thanks for looking

Are you trying to get into helis? Or are you a physics buff or something who wants to do test/calculations/whatever....

I know that if you give us a specific question, we'll have the answer. But I don't know that anyone is going to want to look that all up. Help us help you

maybe i was unclear. so example, say 700e. how do you know what headspeed to start with? then how do you figure how much power is required for this heli?

is there a ratio to figure these thins out?

thanks
