• Drexel University MAV for caves, tunels, and forests.
  • http://www.pages.drexel.edu/~weg22/fwHovering/fixedWingHovering.html
  • Use Microstrain's 3DM-GX1 inclinometer (3 DC accelerometers, 3 gyros and magnetometer... about 1500$). On-board PIC16F? controller.
  • Mass of 600g, Thrust of 1000g.
  • Use small propeller on the wing to compensate roll during hovering.
  • Does autonomous hovering, transition from normal flight to hovering (and vice-versa) and follow the wall.

• MIT Autonomous UAV Aerobatics
  • http://aerobatics.mit.edu/ (see http://aerobatics.mit.edu/videos.html)
  • Use a 100Hz vision system to track the airplane. It then sends commands by RF...
  • Can do hovering, transition from horizontal flying to hovering (and vice-versa) can flying inside a room.
  • 
• Both used an airframe similar to the FlatOuts? series from Great Planes: http://www.electrifly.com/flatouts/gpma1111.html
  • Flatana:
    

Aerobatics Airplanes:

• MiMoYak? (video on http://www.metacafe.com/watch/241796/rc_indoor_flying_extreme/)
  • Variable pitch propeller (able to do reverse propulsion)
  • Blade in the middle of the fuselage... no danger to break it during a crash, or can "touch" the wall with the nose!
  • 95 cm long...
  • Can be ordered at http://www.lipoly.com/
