So, I've built one of these cars before. Back in middle school as part of a shop class we build CO2 cars according to the TSA standards. I have to admit that I didn't spend the most time on it and I was surprised to find it in a box of stuff I recently picked up from my parents house. Note that the black sharpie marking on the car were added when I attempting to digitize the car using photographs. More on that in another post.
|Lame Co2 Car From Middle School|
According to TSA rules there is not minimum weight limit like in the BSA rules. So this car is much lighter than the minimum 5 ounces in the BSA rules. I inspected the crude workmanship of my old car and found several reasons why I didn't do very well in the races in middle school.
- Axels were not parallel
- Guide eyelets (on the bottom of the car) were not well aligned causing the car to go down the track a little sideways.
- The Co2 cardrige was not centered in the car.
- Poor bearings
- Not the most aerodynamic shape
