Learn to Fly 3d RC Helicopters

Predicting which propellers are best to use for your rc quad copter project can be difficult. Computer programs such as MotoCalc can work, but in many cases efficiency predictions can be off by a large amount. Propeller design is an extremely complicated problem, and the best approach is often to test a large set of propellers on a static thrust stand and measure their performance experimentally.

Finding a unified source for this data is also difficult. A group from the University of Illinois have done static testing on small propellers (less than 5...
[​IMG]Are you into RC planes? Many RC helicopter pilots are former airplane pilots, or now fly both. There are many similarities between airplane and helicopter flight, but there are also some major differences that people new to helis should be aware of.

Similarities between RC Helicopter and RC Airplane Flight

  • Both RC helicopters and RC airplanes behave in similar ways when flying forward. Left and right bank will still cause you to turn your heli in the expected direction,...
[​IMG]Draganfly Innovations has made another UAV helicopter. The new Draganflyer X8 follows the same general layout of the smaller X6, but they’ve added an extra arm and two more rotor blades. The Draganflyer X8 UAV will be flying inside a 10×10 foot octagonal cage, inside the conference hall at the AUVSI 2010 international conference. You can see the Draganflyer X8 UAV in action at booth # 2025 from August 24 to 27 2010. The...
The association for unmanned vehicle systems international is the world’s largest non-profit organization devoted exclusively to advancing the unmanned systems community. [​IMG]Ever year AUVSI hosts a major trade show where leaders in both unmanned aerial vehicles (UAV), and unmanned ground and marine vehicles display their latest innovations. This year Draganfly Innovations released the...
