Default brushless esc question

OK...I have a brushless esc that is rated at a min of 12.5 turns. Could I use a novak 6.5 motor on it if I were to adjust the throttle epa to equal the kv/rpm of a 13.5? Would this reduce the amp draw, or would the motor still be pulling high amps and overheat the esc? For example the kv rating of a 6.5 is 6400 so reducing throttle epa to 50% would equal 3200 which is roughly equivalent to a 13.5 kv.

thanks

The short version is no.

The speed controls are rated for a certain number of turns based on how much power the speedo can handle. Even if you turn the EPA way down it's probably going to still pull too much current when you hit the gas from a stop.

You might be able to get away with a little hotter motor than what the speedo's rated for but running half of what it's rated for isn't a good idea.
