Re: Most Competitive Science Olympiad Event

Re: Gravity Vehicle C

Also, just as important as stability, remember to design for adjustments. I've started to see way too many "bolt some fixed bearing blocks onto rigid wood/metal/carbon fiber plates" vehicle designs which probably have terrific precision and repeatability, but can not be corrected for yaw tendencies ...
