Do you still have questions about how to participate in LEAF? Let us answer them for you! Here's a list of our most asked questions:

What is the LEAF STEM Challenge?

The Lindbergh Electric Aircraft Flight (LEAF) STEM Challenge a real-world design challenge geared for students in grades 6-12. In this inquiry-based project, students are challenged to design, build and fly an electric aircraft that will carry out a specific task.

The premise is the same- to successfully design, build and fly a small electric airplane- but the game changes each year. You can learn more about the LEAF STEM Challenge here and read this year's game rules here.

Who can participate?

We welcome the participation of any students- formal or informal- in middle school (grades 6-8) and high school (grades 9-12). Younger students may still participate, but will compete in the middle school grade band. Students who have already graduated high school are not eligible.

How do I get started?

Check out our Resources page! It contains all kinds of materials- most of them free- to help you get started. Sign up to stay in touch too so that you can keep up to date, attend our webinars, and learn about upcoming events like or our coaches workshop.

How much money do I need for this project?

The LEAF STEM Challenge is a low-cost way to teach aerospace and engineering design. Costs will vary since the design is up to students, but the average airplane costs around $12. The flight circle and optional curriculum can be ordered here.

Where can I find funding for this project?

Even though this project is low-cost, funding can sometimes still be a challenge. Check with local organizations for available funding and/or head over to our Get Funding page for a list of possible grant opportunities.

How can I learn more about the LEAF STEM Challenge?

First, sign up to stay in touch to be informed of upcoming webinars, workshops and more. Then, attend a coaches workshop where you can learn more about this year's game and design, build and fly your own electric aircraft! If you can't attend in person, sign up for one of our periodic webinars.

Can I register for the Coaches Workshop with a Purchase Order?

Yes! We are happy accept purchase orders for schools and organizations wanting to register 3 or more coaches for a workshop. Use our handy guide for paying with a PO or contact us to make arrangements.

Can I register teams for the Fly-Off event with a Purchase Order?

Of course! We are happy to accept purchase orders for schools and organizations wanting to register 5 or more teams. Click here for more information.

How can I register more than one team for the Fly-Off event?

Our registration system requires a unique email address for each registration/team, so in order to register more than one team, you'll need more than one email address. For the majority of us who don't have 10 emails laying around, we have a workaround. If you're still having trouble, contact us for other options.
