This is the preliminary model that allowed us to learn the basics of engineering miniature cars, including aerodynamics and the importance of weight. This prototype was made in 2025, we made two of these cars, as at the start of the year there was 4 members in our team and we worked on each car as partners/duos. These cars were made from cardboard cut into special shapes and was considered our team's first test vehicle. Paper Falcon 1 was precisely made by the group consisting of Federico (Car designer and manufacturer) and Alexandre (Team manager). Which beat Paper Falcon 2 by 0.169 seconds with a time of 1.160, averaging a time of 1.180 in 3 races.

This is the first car we have modeled, built, and 3D printed under the STEM Racing regulations. The car was manufactured on March 4th, 2026. The material used for 3D printing was ABS (acrylonitrile-butadiene-styrene copolymer), a common engineering thermoplastic. The entire miniature car was modeled by Federico using Autodesk Fusion, the car fits the STEM Racing requirements for the T3 category. This vehicle employs a lightweight design and a low drag, featuring a rear wing, front wing and sidepods. We had many problems with this prototype but it will help our development of our future cars. These problems consisted of having support materials that were too strong and the holes for the axles and gas canister not being the correct size.

This is our second prototype that has been modeled and manufactured, according to STEM racing rules. It was completed on March 18, 2026. This time, we used ABS (acrylonitrile-butadiene-styrene copolymer) again. However we changed the strength of the support materials for them to be easier to remove. The body was improved to reduce drag. We encountered many challenges during the construction but found solutions for it. The holes for the wheel axles were too small but we used a drill to increase the size to perfectly fit the axles. Another challenge we are now dealing with is excessive weight, and a bit of turbulence caused by an excessively thick and large rear wing. The weight of our car is 105g.

This is our third prototype for our miniature racing car. It was completed on March 23, 2026. This time we also used ABS (acrylonitrile-butadiene-styrene copolymer), and engineering plastic with excellent overall perfomance. Compared to Falcon Prototype #2, we further optimized the aerodynamic shape of the nose to improve the aerodynamics, we did this by smoothing and softening the front nose by making it more curved. We still encountered some challenges during the manufacturing, such as excessive weight and wobbling of the wheels due to imprecise assemble. The rear wing is overly thick, large and high which creates turbulence.
