I have a slash 4x4 VXL (1:10) and it has started to "stutter" when I push the throttle at standstill with a little resistance on the car.(sorry for my english, Im norwegian)
Its not the usual stuttering when using little throttle. Now the rear wheels kinda shakes when the stuttering is going on. And its only with some load on the car, like if I press it gently against the ground and give a small amount of throttle, it just stutters until I give alot of gas, then it takes off. I have checked the rear diff, the front diff, the center drive shaft, taken apart the motor but everything looks good. Can it be the ESC? The ESC is fairly new, got a new one on warranty few weeks ago.
A friend has the same car so well try his ESc on sunday but I wanted to ask if anyone here knows what it can be. When at speed with little load I havent noticed anything. Mostly at lower speeds with load for the engine, like when driving on grass etc.
