Prototype, knocked this out this morning, 1.2 ounces with axles and wheels, can't wait to see how many cubes it takes, what the com is, and how it runs. I was looking at some old winners in our stable and noticed wheel rub against the bodies. So I thought I would try a projecting hub. It has thinned up the car, which will mean more weight. May need to take some from the nose and add to the rear for more weight storage.

Looks good. Are you going to run it straight or RR?

Good question 66.
Alignment and set up for rail riding are my next challenges to study, understand and work into every car from the beginning. If I am reading the posts correctly rail riding is the fastest set up. Fastest being relative to and within local pack rules.
I am interested in Shades comments about hollowed out cars being noisy. What creates the noise and vibration? Air flowing over the packing tape or 1/32 plywood?
I assume in order to weight a 5/16" plank you need enough hollowed out area to fit the needed weight, but can leave the rest of the block wood.

T as the car goes down the track vibration from the wheels & track goes in the car with car being hollow that vibration echoes around inside nothing there to absorb the vibration like the sound coming out of a guitar when you strum the strings. does this make sense

Yes it does, I'm thinking, noise, vibration, energy... bouncing around inside the cavity = not good for speed, need an insulator or dampers like honeycombs. Interesting.
Did this end your hollowing out designs?

yes all my cars now are solid body cars only weight pockets are routered out

Thanks 66 and Shade for the comments. I learn something new everytime I visit the site. I appreciate the insights.
