Problem VS4-10 Ultra

[mlcepeda]

My Kit runs great except when I steer it right or left. The motor does not run smoothly. It’s jerky. Goes fast then slow then fast. It only happens when I steer it. What is my problem? I have a Tekin 3100kv and RX4 esc installed.

Welcome to the sight!

You are going to get more questions than answers dude. Post more info if you can. You'll get better answers.

What servo are you using? Batteries? Is your electronics brand new? Are the leads attached correctly? Using a BEC by any chance?

Sounds like you are binding the CVDs in the front axle. Might need to back the EPAs off a little to keep them from binding.

What does EPA stand for? Sorry, I guess I’m a newbie.

End point adjustment, which is set in the transmitter. It limits the servo travel so you don’t bind the cvds as Almighty Malach says. What transmitter do you have?

Have you checked your center driveshafts to make sure they are phased correctly? Check to see if both “U shape” joints are inserted in the slider at the same angle so they mirror each other.

On my rock jock I had to put shims between the mip driveshaft I bought and the pinion

Could be a brown out
