My first Slash 4x4,(not ultimate one) is playing up. Speed halved, still original ESC, motor and gearing (13/54). Makes a rattling noise either with driveshaft at rear or near gearing/motor. May take video if that helps? Hitting 27mph on the iPhone speed telemetry.
Tried checking gearing, slipper clutch, but nothing done there fixes it. When pulling throttle the esc flashes green, but not sure if it usually does it, not checking on ultimate version yet.
Any ideas? Thanks.
