Inspired by a dad’s comment about the high cost of RC hobbies, this experiment tests an eBay-purchased RC truck’s brushed motor to reach 40 MPH on a budget, using a GoPro Hero 7 on a custom 3D-printed mount to record speeds across 4-6 laps in a parking lot with NiMH (~18 MPH), 2S LiPO (~25 MPH), and 3S LiPO (~25 MPH) batteries; while LiPO offered consistent performance, the GoPro’s weight caused understeer, and a potentially worn-out motor limited results, suggesting future tests with a GPS module and new motor to balance cost and performance.
