Odecom5 gets my vote for Dad of the Year. It sounds like he was able to 'help' his son with this school project and end up with their relationship intact after this complicated build; not a small feat. His son even had a broken arm during the project which may have worked out better for both of them.
I would have been proud of this section alone.
You and I both know that Dad did have all the fun, but the father-son bonding project had to be well worth a few days of frenzied parental competitiveness.
Go to Instructables for the entire project and just look how proud Jr. is with Dad's project. Sweet.
