my mm and mmm problem

[q8-maxx]

hey bl-is-future I'm sorry I did not explain my problem very clear. it was fine before update because the batteries was full charged

What happens to me is: I gently pull the trigger. The truck starts to move, but then it acts like it goes by itself for a second or two no matter what the trigger is set to

BrianG same here lol but I broke my front bumper its not problem I have new one
