Manager Oskar Weigl


Note: this has now been superseded by the Quadcopter v2!

Our quadrocopter is totally custom with a chassis which was printed on our RepRap Mendel. The development process was particularly quick with just 2 weeks between conception and its maiden flight! Was also exhibited at the element14 stall in the UK Maker Faire 2011.

Current Status

Broken frame - waiting for design of 3D Printed Quadrocopter V2.0

Tuning the PID loops

Getting a stable oscillation with only P gain.

Using two screws at the center of gravity to allow free rotation.

  • Note, this accelerometer has too low resolution for this type of application, and will be replaced.
