Interesting sourcebook on model cars and building them even when your child is not doing a scouting project but you are interested in a design for a toy car or homemade toy. I didn't know that these cars all have to weight the same even with different designs and weights, etc. Helpful to adults who may be helping a boy scout or a model car enthusiast build one.
This book is fantastic, assuming the suggestions actually work. I'm looking forward to helping Evan put his Pinewood Derby car together this year. This should be amazing!!!
