Hey everyone,

i hate that my first post is in this direction, but i just got a slash ultimate 4 by 4 and something is wrong

i charged up the battery, followed all the manuel directions and gave it ago

the car is stuttering if i dont give it full throttle....it just shakes like crazy, fwd and back...

if i give it full throttle it sometimes works but sometimes nothing happens

i have literally only used the car for 3-4 minutes......please help
