Maxi-efficient spinning drone from DroneDJ’s favorite Mad Scientist
It’s been a spell since DroneDJ looked in on aerial DIY maestro, engineering whiz, and geek genius supremo Nicholas Rehm, who of late has been working new scientific magic developing a bodyless multi-rotor drone that uses 300% less battery power when the entire craft starts spinning like a detached helicopter blade – and remains aloft with two of its three motors shut down.
Editorial avowal right off the top: Despite Rehm’s efforts in all his videos to make his exploratory home UAV projects accessible to non-experts, even the most rudimentary theorems and calculations used in developing his spinning drone concept are beyond the ken (and descriptions) of this post. What follows, then, is an attempt at ballpark generalizations of his dervish craft – albeit a stadium the size of Alaska to allow for lurching approximations.
Rehm first went about creating a spider-like craft whose three…
