I just took my brand new slash 4x4 platinum out for its first voyage today and i was having and issue with it. In order for me to get it to move i had to give it a boot to get it rolling then it would take off. I have tried reprogramming the esc to the throttle endpoints and it still needs to be rolling to get it to move, i am out of ideas on whats going on. Any input at all would be helpful
