Transforming a signal from a servo motor to ESD arduino

[Symbolls]

So i have a esd motor thati wana put on an RC car that was working with gas and i wanted to trasle the signal from a servo that acted like a gas pedal for the old motor into an esd signal si i can make it work with a bldc motor here is the code i have made so far

 

the signal coming from the rc recever is for servos so that way can only get input like that

 

my signal is from -255 to 255 i need to make a pwm signal betwin 1 ms(stop) to 2 ms(full throtle) and i dont now how to translate the signla

 

At first i was making this whit a DC motor whith a h bridged

 

thx for your time btw
