To discuss the procedure and final selection of Drag Queen structure
To provide analysis regarding the components and method of functioning of the final design
To accurately analyze the aerodynamics of the final design
To present a final design that will work based upon correct calculations

The speed of each motor’s propeller is independent of one another
Thus, differential steering is possible
Motor 2 is on a swivel: when pointed straight ahead its range is 90 degrees to the left or 90 degrees to the right
To add to the idea of differential steering, this will provide greater torque in direction of steering
Used to provide lift and keep LTA stable in case of uneven air conditions

3. Rotation of Motor 2
DRAG QUEEN Features
Our LTA is capable of differential steering and thrusting and also makes use of a rotating motor.
With only 4 controls on the transmitter, we are effectively and efficiently using all controls to create a working LTA.

Alice Fan, 2004
By analyzing various designs and assessing the strength and weaknesses of each, we were able to select a design that provides optimal reliability and efficiency. The incorporation of two large motors allows for better maneuverability and maximum thrust, while the small motor underneath the vehicle allows for stability and lift control. The lightweight design contributes to the improved aerodynamics of the vehicle and provides greater support to the frame of the dirigible. Thus, these features of our team's LTA make it highly competitive and give us the leading edge.
