Re: motor and esc recommendations for 4*
As Michael says , one if the big things is how much clearance do you have ? If flying on grass a minimum of 2 to 2.5 inch clearance and if on hard pack or asphalt then you could get down to 1 inch but more is better.
As you go up in Kv you go down in cell count and vice versa. I would try for 700-800 Kv range and 4S lipo. Some brushless motor manufacturers have prop charts , Scorpion , being one of them. Take the motor max amp draw and add 1/3 to that rating for your ESC .
Always go with the higher watt motor suggestion as you will never run at that except for short 10 second bursts because motors that are rated that way ;are usually never a continuous rating.
