I haven't been on here for a while. Thought I would ask a question or two.
This is my son's last year in cub scouts so he really wanted to go out with a bang. He wants to build the fastest car he has ever made. We decided to hollow out the body leaving it thin on top. We got it down to about 8 grams.
The questions are, what to cover bottom with? The twelve cubes in the rear are glued in.He paints it . We usually aluminum tape the front weights during and after testing. Should we just take the tape up to the front axle to cover the hollow section? Tech has never said anything about the tape on the front weight pocket. I don't know what they would say about three-quarters of the car being aluminum tape. I'm afraid that much aluminum tape is going to put our weight up too high and then need to drop down to 12 or less cubes in the front.
I thought about after we get the car set up gluing in the front cubes and then vinyl the bottom of the car. I don't know.

use regular clear packing tape then. That lets them see everything that is up there for "inspection" and it is a lot lighter than the heavy aluminum tape.
 
Instead of using aluminum tape, and if you don't want to use clear tape, 3M3350 HVAC tape is thinner than aluminum tape, allows you to peel back and adjust your weights if you need to and it has no problem adhering again.

Or vinyl, but usually, it is stick one time.
