My buddy T made up another set of custom, dual flange, front wheel hubs. These hubs are for my Tsunami Electrathon America racer.

Got a reply on the last video, "Somethings you can't scrimp on. You need strength where stress is the most." from (@GaryFeltman) ...so, lets discuss & expand on this concept, a bit more.

I've been working on some new ideas. Like maybe using a mini-hub to add a brake rotor (or sprocket) to a 6" x 3" Azusalite composite wheel.

Found an issue with the rear axle so, we are probably done for this season. Also discuss some drag concerns of the motor & driveline.

Seems like we have most of the "bugs" worked out so, let's try another test run.

While re-torquing the lug nuts, I came across a bearing issue.

More track clean up & tried another endurance test run ...but, it looks like we are still "working out the bugs"

I found a spot that we might be able to set up a practice track. So, my daughter Sierra & I did a bit of clean up (removed weeds, glass rocks & other misc debris) & then, did a couple of quick runs around the track. It's still a "work in progress".

Attempted an endurance test ...but, (stuff happens) it didn't turn out as planned

Mounted a cell phone with a speedometer app to get some speed readings.

Installed a 48V system & addressed or removed some of the "obstacles" that doomed the first test run.

Discussing some of the issues that may have contributed to the motor failure.

After double checking...just about...everything, I figured it was time for a test run but, it didn't turn out so well.

I designed & built another race car in compliance with the Electrathon America rulebook. It has 3 wheels, 3 wheel suspension & a 3 wheel hydraulic brake system. It has a 60VDC operating system that is powered by a 16S 60V Lithium battery pack, protected by a 50A circuit breaker & motivated by a 60V 2,000W brushless motor.
