Have checked the potentiometer at tb3 and it was flawless. Moving from 3.8V depressed to 0.5V fully actuated. Tried to catch the potentiometer in a faulty reading but on the 100s actuation it was good. But what can I say, for me the speed control was working fine at the verification. But the fact with the settings is that truck was ok in the past and I know for sure that nobody had acces to a handset except me so I'm kinda set this option away. I more thinking of a bad component but when it is not always its harder to find... Can the current sensor be the source. In other word, there is a ramp you can adjust to set the acceleration rate and when it reach close to 95% of maximum speed, 1A will close. The fact that it will sometimes close with throttle half depressed and the speed ramp that seems to works ok make me think. How the logic card knows that the truck has reach the necessary speed to close the 1A?? There is no speed sensor on the motor.... So it is the current?
