What material is your vehicle made out of? my vehicle was really slow, so we had to take it apart and substitute the heavier parts with lighter versions.
I have mine made out of wood. It's not a solid block though, it is just a frame. A few of the materials I may be able to substitute would be the pull arm, or maybe take 2 of the CDs off (I doubled up the front wheels). Speaking of which, do you know if having a double-wheel in the front or back effects how straight the vehicle might go? I thought it might help to make it go straighter but it might just be a little extra weight I could take off.
Events I've been on: Elevated Bridge (1 yr.), Ornithology (2 yr.), Battery Buggy (2 yr.), Optics (2 yr.), Mousetrap Vehicle (1 yr.), Awesome Aquifers (1 yr.)
