I think I'm having a problem with the drop pins lately. It seems when the pins release one make take slightly longer to drop than the other. So the car in lane 1 has a little jump on the car in lane 2. When I switch lanes it does the same thing. Has anyone had this problem or something similar, and can anything be done to fix it other than replacing it with something else. Hopefully sooner than later I plan on buying the 2 lane start and finish from 3DBotMaker but I'd like to get this fixed in the meantime. I haven't taken anything apart but I'm also wondering if the solenoid can be replaced.
