sciencetoymaker | Eco-Empirical Dragonfly Helicopter Build @sciencetoymaker | Uploaded December 2016 | Updated October 2024, 3 hours ago.
IMPORTANT UPDATE: Since making this video, I made another video for a design that is a bit simpler and uses more"off the shelf" parts (except the rubber band--school/office rubber bands just don't work well). It is not variable-pitch like this EE design, but for most people the newer version is better. So I no longer have the Eco-Empirical kit listed on the Dragonfly Helicopter store page. If you really need to make a variable-pitch helicopter, contact me. I still have some parts that I'll be happy to part with.
The newer video of the simpler, fixed-prop design is here youtu.be/O77Y2dEvi0s
