JJ-COPTER MK2 STABLE MODE (MEGA,Wii,GPS,Compass)
Mk2 - Frame : Alluminium-Carbonium, arms nylon stripped and glued without screws (only 4 metal screw to connect the main alluminium plate + 4 nylon screw to sustain Arduino and 2 for Wii sensor ) The stability is obtained using DCM Euler Angle and DCM Unbiased Rate in Control Routine in STABLE and ACRO Mode). It is more efficient than standard Aeroquad, the Heading Hold use Compass-DCM stabilyzed Euler angle.AeroQuad – build your own quadcopter - Hack a Day
It hurts us to look at this quadcopter, agonizingly so when we watch the video after the break. That’s because we feel the unstoppable compulsion to build one. This four-rotor helicopter has a lot to be proud of; it features Gyro stabilization, Xbee remote control for very long distance operation, and computer interface for data graphing and calibration. We like the quadcopter that we came across at CES but building one of our own is more fun than buying it ready-made.
Yann's Techno Toys Blog - Shrediquette: an Arduino-based Tri-copter
Shrediquette: an Arduino-based Tri-copter The Shrediquette is a tri-rotor helicopter built by William Thielike from Germany. William is a PhD student in biology, who seems to have many talents: micro-controller system design, control, mechanical design, flying contraption construction, as well as film making. His tricopter is built around an Arduino Pro Mini micro-controller.
This week we adjusted the control surfaces on the Raptor to get it all balanced and flew it a few times to get more experience and test the airframe's performance. I've got to say, flying wings, and the Raptor specifically, have far exceeded my expectations... it flies great! Its very, very stable, has an excellent power to weight ratio that allows it to climb indefinitely, enough control surface and authority to allow a perfect…
