We've got a 5/8 COM with just under 30 grams on the front dominant wheel. Aside from the rolling resistance against the center rail, what's the best way to minimize body/wheel hub friction? I did apply multiple coats of CA and polish both surfaces that make contact with each other, but I'm not sure if there's a better way out there.
CA glue is fine, 30 grams seems a little high on the DFW? I have my kids shoot for closer to 15-18 grams. Do what you can do with the design your scout picks out though.
