Sorry guys, this is the fastest car ever. It's a time machine. It went back in time and won the day before the race.

Here's our entry for the pinewood derby 2021 made by my son who is an Aol. The rules this year said no power tools. The theme for this year was most creative and most funny. My son decided to go with the Among us theme. Our car won 1st place in the AOL race and won 2nd place for most funny.

Blue lightning

My son; car. Blue lightning. It won every heat, except for one second place finish, and was third over all, first in his age group. He is headed to the district races!

The kids put their first coats of color on last night. Tonight we’ll wet sand them with 400 grit and then put a second coat.

Pit area for set-up.

What are you guys thoughts on weight placement?

Weight in front or behind rear axle?

From what I remember friction was ten times more important than weight or aerodynamics. The kids with the polished axles, smallest grain graphite and thinnest wheels always won against the flat cars with standard tire assembly. Weight placement was next with it needing to be as far back (making it as high off the ground as you could) as possible without making the car tip backwards so that you got maximum potential energy. The shape of the car really wasn't that big of a deal as the kids with the pencil or other blocky designs didn't do too bad against the fancy designs all else being equal.
