My revo 1/16 model is only 4 months old. I have only used twice and it has sat for only a month. Charged battery for the required amount of time and went to us it on 1st setting and it went 5 ft. then stopped. Still had power was able to steer just no throttle. Does the same thing on the second setting. Tried the 3rd setting (training mode) and it works fine. I tried the speed control re calibration but it still does the same thing. When it stops the red light blinks but the battery is fully charged. Any ideas of what is going on?
