These builds are stunning! Watching the implementation of different theories and techniques to achieve the same goal is great to observe. I will be watching this proxy in awe. I will need to address my weakness of brass chassis, tuning, truing, general assembly and precise measurements in 2018 so that I to may compete one day.

@ DRW21 - gorgeous chassis builds for Tony and yourself, but please clarify the rims being used. From the outward face, they don't seem to resemble the provided RS Slot Racing RSW002 rims. Have they been modified?

Better to clarify things now.

Hello all, the rims used on the 2 builds I have done are the same rims as received along with the motor and body.
When reading about them being a little bit loose on the axle I purchased Slotting Plus axles as they were a tad bigger than the Slot-it axles I normally use.
When it came time to start building the cars the rims were still loose and quite wobbly, way too wobbly for my liking even with the bigger 3/32 axles.
What I have done to eliminate the wobble was to peen the boss of the rims to tighten them so that they fitted the axle better, that gave me rims that fitted the axle snug but still with some wobble.
I then turned them down in a lathe to true them so that they spun true.
The the end result is these are the correct rims, just tidied up.
Hopefully this is OK. if not please let me know.
Cheers Guys - Dave

OK, I want to open up my motor to "tidy it up" too! :lol:

After doing some weight tuning, it seemed my chassis worked better with weight added to both the front and rear, so I beefed up the front plate and added some plates to the rear. The total weight is now 67g. I also did my usual mediocre and simplistic body preparation, and switched to a plastic spur gear, which is much quieter and smoother than the alloy one.

The co-organizers have conferred and are in agreement that in the spirit and intent of the proxy for "period appropriateness in the modeling and performance of the day", we'll rule out DRW21's wheel modifications. That applies as well to the modification of the other hand out parts including the motor, tires and body unless otherwise stated in the rules and guidelines.

We apologize for not stating this at the beginning but hope this is clear now before tech.

This is a good time to remind everyone that the postmarked deadline for arrival is January 19, 2018, really not that far off.

I'll provide the mailing address via email as I've got everyone's except Austin and Tusco Todd. I can inform them via PM on this forum.

Duke - I’m fascinated by your minimal chassis. I look forward to driving it in person.

Adding the brass plates was definitely an improvement, stiffening the rear of the chassis and increasing the stability. It shaved about 0.3 s off my lap times on Luf's track. The car will still sometimes tip when pushed to the limit, but it's pretty well balanced. I still have my doubts that an anglewinder is the best configuration for a car of this size and motor - we'll see how it does against the in-lines.
