            Structural Analysis
   Structure:          65g x 1 = 65g
   Motors:             93g x 2 = 186g
   Motors:            269g x 1 = 269g
   Propellers:         5.2g x 3 = 15.6g
   Servos:             43g x 3 = 129g
   Radio Gear:         46g x 1 = 46g
   Batteries:         260g x 1 = 260g
   Total Mass:            approx. 970.6g
   Payload:               approx. 729.4g

   Dimensions:
    Length: 2m    Width: 1.25m   Height: 1.5m
         Aerodynamic Analysis
   Helium Required:
      Lift=ΔρVg=17.15N
      Assuming two balloons, their radius must be
      .53m to generate the necessary lift
      Thrust must be equal to drag in steady flight
      Thrust = Drag = 2.64N
      v2=2D/ρSCD v=1.5m/s

      Total course time estimate: 60 to 70 sec.
          Control Analysis
 Yaw control is provided by two
  oppositely facing, fore and aft
  mounted small motors
 Pitch control is provided by the third,
  main drive motor, which pivots about
  a horizontal axis
 Control surfaces will be added if we
  deem them necessary after initial
  flight testing
