well something is wrong with my truck now.. i have 2 batteries for it the stock 3000 mah and i have a 5000 mah nimh as well. i ran the truck first with the stock one ran great everything worked properly. then i took about a 10 min break and ran the truck with the other battery. i noticed the reverse wasnt working.. i picked it up and went forward a bit and noticed when the tires came to a stop they started spinning backwards by themselves ? i then looked at the esc and noticed theres no red light on it, i couldnt get it to shutoff unless i pulled the battery pack out. i then put the stock battery pack in thinking it may be the battery since it just happened when i swapped them. it still didnt work and the esc kept flashing green? im new to this stuff.. thanks in advance
