need some help
 

i just traded for a mini latemodel with brushless motor and spektrum 3.0 radio when i went to run car lastnight in parking lot and check it out it would jerk when it first took off then would go and when you let off and gave it throttle again it would go in reverse and go about full throttle and you would have no control over it any ideals what would be wrong?

Make sure there are no cuts in your receiver antenna. Also, make sure this is not wrapped around anything.

also sounds like a cogging issue..recalibrate ur esc to the radio.and if running a senor cable..it also might be bad..try calibrating first though.

Yea! +1 on the radio
 

You need to check out your radio. :nod: Somethings a miss there!

Did you get all this together? Was it working before you traded, or were some changes made with the radio or rcvr before you got it? It sounds like the radio needs to be calibrated to the esc. Whenever there's been a change in the radio, rcvr, or esc, radio needs to be re-calibrated to the esc.

Probably a radio to reciever problem or possibly check all esc wiring for any exposed wires.

thanks guys i changed receivers and it is working fine now
