The few times I've tested out my car on the ground, it has not performed well. First, the manual speed controller seemed quite intent on spinning the tires when it was in neutral. Small manual corrections fixed that, but did make me keen on getting ESCs for our cars, and they are just a ton better. Whenever I held the car and tested it, the tires spun quite well, and steering seemed good as well.. but on the ground, the tires just spun for a few seconds, then it quit, and the car would either jerk forward, backwards or quit, without any real indication of why. On the kitchen floor the tires stun a lot, and it shot forward for a few feet, then quit, then occasionally jumped back.. It seemed to accomplish little beside putting a ton of skid marks on the kitchen floor. With the ESC installed, I still wasn't getting any good results, so I decided to try it out on the sidewalk outside. While out there [with no results once again] Rachel spotted something. So we headed inside, and took this video.. Notice anything?
