📐 How We Calculate
  • Speed: Based on motor power, prop efficiency (~55-65%), hull drag, and rider weight using simplified propulsion physics
  • Range: Runtime × average speed, accounting for duty cycle (tow boggies don't run continuously — you tow, release, reposition)
  • Runtime: Battery capacity ÷ average power draw, adjusted for riding style duty cycle and ESC/motor efficiency (~85%)
  • Cost/session: Electricity cost (~$0.15/kWh) + estimated wear (~$0.50/session for prop, bearings, rope)

⚠️ Real-world results vary based on prop pitch, current, wind, rider skill, and battery health. These are educated estimates based on 100+ community builds.
