Went 10.75 miles at 386mAh/mile with dual batteries & the gopro tower, but it cost tire rubber.  A CA glue coating wore off or fell off.

It was time for some other materials.

After 8.6 miles, a common shoelace adhered by E6000 did better than any other material.  Although the adhesive itself ground off & the fabric was quickly grinding off, it was the 1st sign a protective coating could definitively stick to the tires.  The solution was now just a matter of sticking a denser rubber on.

Sadly, the paw controller died on this drive.  After switching to phone control, the screen locked up & it drove into the middle of the street.  Must remember not to use phone control near traffic.
