Working on my third battery, went to the skateboard park the next town over and ran on some of the jumps. There was a large one that I tried and it went about 15 feet in the air and came down right on its nose and just stopped. I checked it and the connection came loose. I plugged it back in and the ESC wouldn't go through its cycle and made funny noises when I pulled the trigger. The steering worked OK just the grinding sound from the motor. When I got home I noticed one of the leads from the motor came loose as well, I connected it back up and we're off to the races again...I can't jump worth Sh!t, when the car goes up in the air, it's like I'm hypnotised and fascinated just watching it in the air and don't pull the trigger to try to straighten it out, I know what I'm supposed to do, I just don't do it. practice, practice, practice...
