There is no fee to students or parents participating in our program. 88CHARLIES Mentors volunteer their time to promote the efforts of the organization. That said, 88CHARLIES is supported solely by volunteers and generous donors. Make an impact on tomorrow's youth by making a charitable donation. Monetary donations are used to purchase parts, tools, and materials to build aircraft, as well as to cover building and utility expenses. 100% of your donation goes directly to the cause.
