For power-hungry 3D applications and heavier scale machines, is it better to generate the required watts with more amps or with higher volts? Let’s look at some real-world examples and see what’s going on behind the curtain. JOULE’S LAW The crux of the problem for high-current power systems is that power losses increase with the [...]
“He’s out there … flying the most lethal weapon ever made: the Blue Thunder Special.” Remember this early ’80s movie that starred Roy Scheider flying a highly modified Aerospatiale Gazelle? This RC 1/4-scale version is the handiwork of French builder Eric Meaux, who created it from a Heli Factory kit. The 24kg heli is powered [...]
Here’s a nice twist on the video-equipped quad copter: Chris Geiger and his UAV are helping firefighters in Fresno avoid danger! Here’s the scoop from CBS 47, and be sure to watch the video below. Hovering above the Scottsmen Apartments the dangers become clear. Charred beams and collapsed rooftops provide a maze of obstacles that [...]
While the IRCHA Jamboree is best known for incredible 3D flying, there are also some outstanding scale models to be seen in the dedicated scale area. This year there were some big and impressive scale models on display, but my personal favorite was a truly amazing Sikorsky SH-3 Sea King that was the handiwork of [...]
To control the direction of a heli during a pirouette, pick an imaginary rference line passing through its center. Every time the helicopter’s nose come around and crosses that line, give a control input in the direction you want it to go. For example, if you’ve done a pirouette in a hover in front of [...]
With technology that brings the stuff of science fiction movies to life, scientists have been able to fly an RC quadcopter through an obstacle course using thought control! Check out the news and amazing video from the BBC: Researchers have harnessed the power of thought to guide a remote-control helicopter through an obstacle course. The demonstration joins [...]
Flying model helicopters is exciting and fun and looks very easy, that is, until you try it. Unlike model airplanes, helicopters lack stability and must constantly be controlled in all the flight axis. The pilot must develop the reflexes to control it, and this takes practice and commitment. By following these 10 steps, you will be up in the air in no time.
