burned 3594mAh or 335mAh/mile, so the transmission rebuild with new tires was the solution. The maximum single battery range would be 13 miles again. It had the headlights on, the speaker, & carried 5oz of food back. The wheel diameter had to be set to 110mm. It had worn down to 108mm. No obvious signs of wheel alignment error, but it's hitting right near the highest efficiency. A rain storm passed through, but the paw controller continued to work.
Desperately need a way to access the 1 bushing. It's on the end of a shaft & the shaft is pressed into plastic. It may require a teardown every 2 months or when the range is needed.
