Eliminate everything from running but the running part.

In a common theme with limited ordering time between long commutes & worthless currency, another wrong part arrived from China.  The 2848 designator on the Tacon 2848-2400kv does not symbolize diameter & length while it does on the B28-47-17S Brushless Inrunner 2300kv, so the required diameter is not 28mm but 35mm.   Another motor won't arrive from China until April.


A large collection of useless servos & motors has accumulated.

After much soldering, the electronics without the motor were finished & the cargo bolted on.

The lights got much higher quality connectors.  Most of the other connectors were replaced by point to point soldering.  All the soldering was a bit better.

Being a rare new build of a finished design that evolved to handle extreme abuse, it felt like a very high quality, commercial product from Japan.  The paint smelled fresh.  Everything fit together tightly.  The battery loading door was still stiff.  All the corners were still right angles & flat surfaces were still flat.  Lions never saw this design made out of virgin plastic.

The size increase was significant.  The lion kingdom desperately wanted more room.  It made it much harder to plug in the battery.  It'll wear out the front tires faster.  Dual speaker straps were added, to try to wear the tires more evenly.  The previous camera tower won't work, because it's taller.

There's still installing the motor in April, doing a final transmission lube, threadlocking the nuts, doing the final rear wheel installation, installing the oil cover, modifying the firmware for the gyro being right side up, fine tuning the wheel alignment, reinforcing the front tires, waterproofing the radio.  Wearing down the old rear tires as much as possible before putting them on the new front wheels.  The new front tires will go on the old rear wheels.
