Things that Went Well
On our trap using Meccano went well. it made it easy to attach parts and take them off. Our distance was actually pretty good we just have to make sure we set the car off at the right angle to get our maximum distance. Our car wasn't that slow either.
Recommendations
Make sure to use light weigh materials and tires that have traction. It would be a good idea to have two sets of wheels. A larger set for distance and a smaller set for speed. Try to avoid friction on the axle. When setting to the trap make sure the string to wound up tight and is a strong string so it doesn't break. Make sure to test your car out many times to know exactly how it works. If it turns to the left start it off pointing a bit to the right.
