Need Help ! Remote without ESC/VESC

hey guys

I am new to all of this so i just start with my Question.

A friend of mine has a receiver a Brushless motor and a servo connected togehter to controll the torque

so my question is, is it possible to controll the servo with a remote with arduino and a nrf with 2,4 GHZ

thank you for your answers

I would like to see how he wired these, because it sound very odd. You need some kind of electric controller between motor and battery.

ok so the motor is seperate he controlls the motor trough the servo and the pwm signal goes to the remote

the motor is a little bit special because you cant get to the software or anyithing

is it possible to pramm the servo trough the pwm to do what i want ?
