H King's 1st drive


Hussled the fabrication quite a bit, in the slight chance it would actually work in time for overload week, but the 1st drive quickly showed it had a long way to go. It was clear that the lunchbox would be the weekday driver.


It was decided that there was still no way the electronics could go on the chassis, so back on the container they went. The electronics were covered in rubber from an exercise band. All the voltage regulators went on 1 side, in a power farm. There was no way to keep that from sticking out, because it would melt plastic.


The ESC went into the H King's original battery compartment. Another creative battery tray was developed. The integrated vehicle was a menagerie of duct tape, packing tape, scotch tape, & hot glue.


The tachometer detected a lot more revs to hit the same speed. Braking was ineffective at low speed, though still functional at high speeds. Steering servo didn't have as much throw as the Ruckus. The slightest downhill made it freewheel, at which point the tachometer didn't detect an RPM & it oversped. Suspension was still a bit soft. The plan is to make it rigid. It was a lot more stable than the Ruckus while carrying the shirt, phone, & heavy speaker. Motor stalled quite often when starting & when hitting bumps.

Finally, the battery died after only 5 miles. A lower KV motor with larger pinion is the leading candidate. At least, it was incredibly quiet compared to any previous vehicle.

Now the speed test:
