Oliver Garrow, President of Garrow Aircraft, LLC in Mountain View, California, has been developing the Verticopter® concept for the last several years, and made a dinner presentation on his design at last year’s Electric Aircraft Symposium. Garrow’s Verticopter uses pivoting motors to provide vertical and horizontal thrust, with tip and tail thrusters fine tuning low-speed maneuvering capabilities. Verticopters will come in all sizes, with a single-seater ultralight as an entry-level machine and an inexpensive way to test the concept, especially when one uses a low-cost model aircraft motor unit from Turnigy (distributed by HobbyKing in Hong-Kong, P/N CA120-70), and a SPIN 300 Optically-isolated electronic speed controller (ESC) from Jeti for power – at least for the wing-tip thrusters. The motor shown costs a mere $299 for its promised 20 horsepower, while similar German and American units run over $1,000, with similarly high prices for controllers. Testing shown in the video was carried out with lithium-polymer battery packs arranged in a 16S2P configuration …
