I truly appreciate all of your advice! I've learned so much from this forum and you have been so helpful!!! This morning when my plumber was over, we started talking about RC cars because he's worked with them for years. He took a look and suggested exactly what alvinlwh has above. When I changed out motors, I didn't tighten the hex screw on the flat part of the pin on the motor. Once I did that it worked!!!! WHEW!!! Thank you all so much for your troubleshooting and help!!!!
