Hello all. I have a mini project on hand which is to create a remote controlled motor which in turns control the throttle cable of a dyno machine. I have a plan on hand which is to use an RC motor connected with a pulley. however to control the speed of the motor, i know that a transmitter and receiver is required. hence, is there any other ways to control the speed? Also, how do you connect a pulley and an RC motor together? Thanks!
