my mini revo was fine a couple days ago now all of a sudden it starts to jerk when i lightly touch the throttle i readjusted the slipper and remeshed the motor so it's not to tight on the spur but it still does it any thoughts

hear any clicking or grinding from your front or rear diff?

no there is no clicking

Disconnect the steering servo and try it ,
When the steering servo goes bad in these cars it will cause irradic operations

i'll try that but i hope it's not since i just got the car 2 weeks ago but i'll repost and let u know the out come

Yeah I'm nearing ya, you need to set end points so the steering doesn't bind on full lock this puts stress on your servo motor and burn it out n cause glitching
