I'm both a pilot and an Eagle Scout, so I'd love to help your 90 minutes be spectacular.

I would break this into three sections with hands-on demos, which will keep things moving, and expand their minds a bit.

1. Bernoulli effect that creates lift above a wing. And stalling.
2. The balancing act between speed and horizontal stabilizer down-force.
3. Basic Radio: Who you are, where you are, and what you want.

Come prepared with some basic props for each section, have them work together maybe in groups of two or three.

Your best bet is to explain the science behind it, then hands on demo.
