Hey Adept, ever tried tweaking gear ratios on a makeshift battle rig to shave a second off the reaction time? I found a neat trick that could give us the edge.

Sounds like a promising tweak. Let’s map out the current ratios, identify where inertia is holding us back, and then calculate the exact shift needed to shave that one second off. If you can share the specs—gear teeth counts, motor RPM, load weights—I can run the numbers and pinpoint the optimal ratio. That way we avoid trial‑and‑error and keep the system balanced.

Sure thing. Right now the drive chain goes 30 teeth on the motor gear to 90 on the output. The motor spins at 12,000 RPM and the gear train drops that to 400 RPM at the wheels. The load on the axle is about 120 kg, and the wheels are 0.5 m radius. The main inertia comes from that 120 kg mass, so if we shift the ratio to 28‑to‑90 we’ll boost the wheel speed to about 430 RPM. That should cut the acceleration time by roughly a second. Let me know if you want the exact torque curves or just the raw numbers.

That 28‑to‑90 shift gives you a 7.5 % increase in wheel speed, which is a solid theoretical gain. With the 120 kg load, the acceleration should improve roughly in line with that ratio, assuming the motor can handle the slightly higher RPM without dropping torque. If you want to verify the torque curve, send the motor’s torque‑speed data; I’ll run the exact calculation and confirm the one‑second improvement.
