XRAY - Model racing cars

Hi i am new to this hobby i have a xray xb8ec and struggling with the steering
if i turn right it has a long turn radius but if i turn left it turns sharp i did have the servo on centre and the radio on zero it's a spectrum dx3.0 any help please

Sounds like it could be the end points to me. I run a different radio so i can't help you find them, sorry.

Turn the transmitter on and pres the scroll button 1 time.It will say EPA on the left side of your screen.press the channel button untill ST(steer) is on the upper right side of the screen.turn your car electronics on and steer full to left or richt.Now you can increase/decrease your endpoint.Dont set them to high cause that will kill your servo's.
