One of our members gave us a presentation on electric flight a few months back. It was very informative. He posted his presentation on our club's website:

We have recently had some guest presenters as well. One was from a local model rocketry club, and another was a woman from a local photography club who specializes in military aviation photography. I missed the rocketry meeting, but the photography presentation was very interesting.
