Double checking wheel alignment
I centered the racer on a big piece of cardboard
...using a straight line on both the rear wheel
...& the front of the chassis
Next, I used a couple of boards (placed along the outside edge of the front wheels)
...to help align the front wheels (with the chassis)
...& then, to adjust the "Toe" of the front wheels (inwards just a bit)

I did up a video kinda summarizing most of the modifications that I've made recently
...& even did a test ride/run
* Spoiler alert...I didn't have ta push 'er home...this time

Drum brakes don’t have drag.

The wheel assemblies run nice and true! Thats nice to see.
Would putting stronger springs in the calipers help them to retract?

There are no springs in calipers.

Hey T,
Yup, your hubs work fantastic
There is a huge size & weight difference between the (2) different Calipers
Hydraulic caliper on left & a mechanical caliper on the right
Hey Denny,
Well, these hydraulic calipers don't have any type of retraction springs, on the piston side
...but, they do have a couple of small springs, that keep the outer pad "in place"

I did another quick test run 
...& also, got some speed data
...plus, throwed in some direct drive vs. freewheel analysis

The Buckinghams said it best, “Kind Of A Drag”. Maybe you’re next hub could incorporate a sprag?

Those are self adjusting spacers.

The racer has been doing so well, I figured it was time to take 'er out for an endurance run
...start off with a 15 min run
&
Then, "if" everything seems "good", maybe keep going for a whole 1/2 hour
...but, nope, today was NOT the day
* This is why test running a racer is so important, BEFORE a race

At least it was not a catastrophic failure!

I've been looking for a test track site, to be able to test run my racers 
Here are the requirements, as per the EA Rulebook
* I highlighted most of the important stuff
COURSE REQUIREMENTS
Events are typically held on parking lots, paved race tracks or velodromes where access onto the track can be safely controlled. EA strongly encourages events to be held on actual race courses when possible. This is to alleviate hazards inherent in street courses. Where road or parking lot courses cannot be avoided, extra care should be taken to identify possible hazards and have them barricaded or flagged to prevent collisions. Such hazards shall be identified and strategies for avoidance discussed at the drivers meeting Courses must be closed to all other vehicular traffic. Adequate precautions must be taken to prevent access onto the track. This may include, but not be limited to, signs, barricades, banner tape, and traffic cones.
Courses should be free of obstructions such as chuck holes, speed bumps or protrusions that would create a hazard to the competitors. The entire course surface should be the same material and texture. Dips or bumps which may damage the vehicles must be corrected or sanction will not be possible. Barricades must be provided to define the course and may include traffic cones, saw horses and police tape and/or hay bales, etc. Courses should be clearly marked to identify all corners, boundaries, start/finish and any obstacle that could pose a safety problem. There must be a positive physical barrier between spectators and the course. The barriers surrounding the course must be sufficient to stop Electrathon vehicles. Street curbs are not an effective barrier. Hay bales, tire walls, or suitable barriers must be provided to separate the course from spectators. Spectators must not be allowed near the course. Specified spectator areas should be designated with signs, barriers, or at minimum marking tape. There must be enough personnel/security provided for crowd control. Road Course layouts should be designed to offer a variety of turns and straights unique to the location. Courses from 1/4 to 2 mile lengths are used. Courses should alternate from clockwise to counterclockwise from event to event, to reduce tire wear, vehicle stress and offer variety. However some race tracks are specifically designed for vehicles to travel only in one direction. Do not run in a reverse direction if it compromises safety in any way.
Courses should be of adequate width and length to safely accommodate all competitors and allow safe opportunities to pass and maneuver. If a course cannot handle the number of vehicles present then separate heats should be run with a safe number of vehicles in each heat.
LENGTH MINIMUM COURSE LENGTH FOR A SANCTIONED EVENT:
Flat Course: 1/4 Mile (1320 feet, 402.34 m) Banked Course: 1/4 Km (820.21 feet, 250 m) Courses should be long enough to permit vehicles to attain their top speed at some point on the course. A 500-700 foot straight is desirable. Course length must be measured with a measuring wheel. On an oval track the distance is measured as the minimum distance a vehicle's inside tire could travel. On a track with reverse turns, the distances are measured with tangents from inside turn to inside turn.
The distance covered by a vehicle in one hour may be determined by an alternative method if that method can be shown to be more accurate than the current method, and has prior approval from the board of directors. An alternative method may be used to determine an official record of distance/time, but may only be used to determine the finishing order of a race if every competitor uses the same method.
WIDTH RECOMMENDED MINIMUM COURSE WIDTH: 25 feet
Course width must be free of obstructions such as cones, barriers and channels.
Surface must be same across entire width.
There may be no obstacles in the entire course width which would limit the free movement of any vehicle from side to side.
RADIUS MINIMUM CORNER CENTERLINE RADIUS : 25 feet
So, basically we need a good sized, close-able course, that's paved
...& I have some potential future ideas, like in some of our local college university parking lots &/or large Church parking lots
...but, probably gotta "drum up" some interest/support in the program, first
So, check this out:
The old Champion Spark Plug site is only ~1 mile from my house
...it was the main factory & world headquarters for years
...but, it's all gone (they are probably Made in China now)
It's mostly just a big 'ol weedy fenced in parking lot now, surrounded with No Trespassing signs
But, I found a couple of over-flow employee parking lots
...across the street from the main factory site
...that are not fenced in
...or have any signage whatsoever
So, I'm gonna do a little bit of clean up like
...broken glass, rocks & bricks & garbage
Also, remove some of the "natural speed bumps" grass/weeds growing thru the cracks
...& then, "run" Sequoia around a bit
...like this (my daughter Sierra helped & got in on the fun too)

Hey WTR,
Its a ways back
...but, info about the steering wheel is in post #346 - #371
Here is a pic of the "flip up" steering wheel mount
