Here's Dan Shapiro's geeky, fun, and inspiring five-minute Ignite talk about becoming a remote control hobbyist for under $100. He writes:
I've done a number of Ignite talks (5 minutes on a geek-friendly topics) but this was by far my favorite. Topics covered:Geeking out aero-style for a hundred bucks
* Helicopter aerodynamics
* Battery technology
* The scourge of GDS, Glue Deficiency Syndrome
* Moore's law as applied to RC aircraft and most importantly
* A detailed buying guide that will get you airborne for under a hectobuck.
Also a few shout-outs to little known aspects of the hobby world, like flying boats and 150 mph+ gliders. If this doesn't make you spend a few bucks on getting cheap chinese electronics airborne (and then suddenly and unexpectedly groundborne again), nothing will.
