My project's requirement isn't limited to a mousetrap car but that's what I've built. My car has to go up an incline of 5 degrees. I'm aiming for a distance of 14 meters. My car right now can go on a level surface but can barely pass the 1.5 m on the incline! My dad is helping me with the project and right now we're going to try to see if a thicker axel will make a difference in its power. Is there any suggestions? Thanks.
