Max,
Good topic.

We've given a few presentations at the club and the more popular ones were on covering techniques, repairing crash damage, glow engine care and repair (stripped down an engine to show how), electric planes (set up, battery packs, charging and ESC's).

We had a video library for awhile. It was good but no one wanted to drag the box of videos from meeting to meeting, so that kind of died. Had crash videos, jets, some video magazines, covering techniques, Dave Patricks series on aerobatics.

Good luck with your endeavor.
