Gyros 101: Make your model fly better | Model Airplane News | Find Articles at BNET

Gyros 101: Make your model fly better | Model Airplane News | Find Articles at BNET: "What is a gyro? Quite simply, it is a device that can sense rotation. It's handy for changing aircraft and helicopter flight and response characteristics, since the model has to rotate when it's disturbed by wind gusts or maneuvering. We can use a gyro to reduce aircraft rotations and 'smooth things out.'"

AR Drone - View topic - Night Flight

AR Drone - View topic - Night Flight:

"I rigged some nice bright LEDs on my AR.Drone for night flying. It works great! Makes for a very cool 'ground effect', plus it helps the downward facing cam lock on for stabilization."

Electronics for Radio Control Models

Electronics for Radio Control Models:

Homebrew electronics, several different applications for RC.

Peak Servo Current Tests

Peak Servo Current Tests: "Measuring servo current with a multimeter or Wattmeter won't tell you how high the peaks get. For this you need an oscilloscope, which traces a graph of instantaneous voltage vs. time. To convert the servo current to a voltage, I made a current probe with a 0.1 Ohm resistor inserted in series with the servo's negative power lead. I set the 'scope input attenuator to 50mV/div, giving a display of 500mA per division. The servos were exercised with a servo tester set for slow rotation. This simulates the small movements that typically occur in flight."
