Waterloo EV May Race
Introduction
After the October race, we rebuilt the drivetrain from the ground up for the 2026 Waterloo EV Challenge. The goal was more power and better reliability — so we designed and fabricated a custom dual-motor gearbox housing two Kraken X60 brushless motors, competed in Heat Race #2 as kart #839, and walked away with 4 awards including 3rd Place and Top Rookie Team.
