Gearing & speed

Everything between the motor and the tire: ratios, rollout, and what the car should theoretically do.

Gearing & speed

Gearing & theoretical speedMotor RPM, wheel RPM, FDR, and rollout in one setup.
FDR & rolloutCompare gearing without motor or battery inputs.
Target pinionFind required FDR and candidate tooth counts for a target speed.
Tire size & gearingCompare tire diameters and preserve rollout with corrected gearing.

Measured passes

GPS speed comparisonCompare measured speed and save each pass with its setup snapshot.
Compare A & BSee changed inputs, speed, gearing, and rollout against a baseline.
