I am trying to control/set speed of my dc brushed motor using cytron dual channel motor driver in manual and auto mode. But no matter which parameter i change, speed never drops to zero when i bring my left stick down or max when i bring it up. When armed it starts with random speed. And when i bring the stick down to trim it slows down a bit and speed up a bit when brought to both the extremes in manual mode.
Also, in auto mode after arming motors they start running at random speed. I have tried changing cruise throttle and cruise speed but nothing changes the speed. Please help.
