3. EE/CS 481 Spring 2008 3Founder’s Day, 2008 University of Portland School of Engineering Background Features of this project -Takes off/lands like a helicopter, flies like an airplane -Controlled by software -Feedback through software -RC Perspective Change

4. EE/CS 481 Spring 2008 4Founder’s Day, 2008 University of Portland School of Engineering Background Design objectives -Physically demonstrate control responses -Display telemetry sensor data on computer in meaningful way

5. EE/CS 481 Spring 2008 5Founder’s Day, 2008 University of Portland School of Engineering Methods How we achieved our goals -Much of the control/display processes are in software --Easier to make changes without modifying the hardware --Custom code and assistance from Eagle Tree Systems and Control Anything -Hardware is off-the-shelf products --Easy to replace --System-wide compatibility
